BIOLOGY i. oni-^e^o, B^n By F. S. EARLE. V /A , : ,, I ; O K ; K; In planning a botanical collecting trip to Southwestern Colorado our objects were first, to secure sets of plants rep- resentative of the flora of this interesting region ; and, second, to study in the field the effect of altitude and exposure on the variability and the distribution of species. It was at first hoped that we might be able to examine some- what critically the La Plata Mountains in the extreme South- western part of the State, and also considerable portions of the larger neighboring range of the San Juan. Lack of time prevented carrying out the latter plan, the work being confined exclusively to the La Plata Range, and the neighboring lower levels. The region proved ad- mirably adapted to the purposes of the expedition. The Range is isolated, and though small in area is of consider- able altitude, the central peak, Mt. Hesperus, holding its rugged snow-streaked crest at the height of 13,300 feet. As seen from the west this mountain presents a peculiar and fantastic appearance. The portion above timber line is a regularly outlined rock pyramid formed of nearly horizontal strata of various colors giving a curious banded effect ; while numerous gulches filled with snow mark it with vertical lines of white. Mt. Hesperus is flanked and supported on the North by Shark's Tooth, a pinnacle of rock well deserv- ing its name ; on the South by the jagged double peak of Mt. Moss, or Mt. Hayden as it is locally called, and on the East by Snowstorm Peak, which justified its cognomen dur- ing our stay in its neighborhood by covering itself with a fresh coat of white in the middle of July. None of these 2 PLANTS BAKERIAN.E. outlying peaks rival the central mass of Mt. Hesperus, but all reach nearly or quite 13,000 feet, and their sheltered gulches hold .buadaut snow far into the summer to feed the mountain, brocks, and furnish moisture for the luxuri- &i it plpirie vegetation that springs up like magic as the snow line retreats. From the basins between these peaks arise many streams. The La Plata River rises to the east- ward of Hesperus and flows nearly due South ; East, Middle, and West Mancos creeks flow from its western flanks, all uniting above the town of the same name to form the Mancos River, which flows in a southwesterly direction. Bear Creek rising North of Hesperus, between that peak and Shark's Tooth, flows to the northwestward, while the drainage from the eastern side of Shark's Tooth and Snowstorm Peak and is tributary to the Las Animas. Two of our party reached the little town of Mancos on the Rio Grande Southern railway on Tuesday, June 21, 1898, and went into camp near the river to await the com- ing of the third member who had been detained at his home in Mississippi by a suddenly-imposed yellow fever quarantine. The valley at Mancos is from one to two miles wide. For- merly a sage plain, it is now, thanks to irrigation, mostly covered with green wheat and alfalfa fields. Owing to its elevation. 7,000 feet, corn and the more tender vegetables can not be grown on the Mancos. To the North and East the valley is bounded by the foot hills and lower ridges of the La Plata Range, the snow-streaked top of Hesperus being plainly visible. The hills bounding the valley to the South are strikingly different from these in conforma- tion, being flat-topped with precipitous sides, evidently belonging to the great mesa formation of the Southwest. The steep northern slopes of these mesas facing the valley NARRATIVE. 3 are covered by a dense growth of chaparral, giving them in the distance a deep blue or almost black effect. This cha- parral consists largely of scrub oak Quercus undulata inter- spersed or sometimes almost replaced by clumps of Ame- lanchier, Peraphyllum, Rhus, Fendlera, and Cercocar- pus. The summits of the lower foot hills on either side of the valley support a scattered growth of nut pine and red cedar, Pinus edulis and Juniperus monosperma. Looking west- ward the eye wanders over great stretches of undulating sage plains and pinon-covered ridges to the Blue Mountains of Utah a hundred miles away. Southwestward the view is limited by the less elevated Ute Mountain Range, lying distant some thirty miles. The five days of a necessary detention at Mancos were devoted to the flora of the valley; and these proved quite as instructive as any equal portion of time spent at higher altitudes. Three well-defined floral belts were reached from this riverside camp. First, the flood plain of the Mancos, a narrow bottom, varying from a few yards to a quarter of a mile in width. Some parts of it are grassy and meadow- like ; others occupied by swampy thicket. The largest trees are those of the narrow-leaved poplar, Populus angustifolia ; and this was the only member of its genus seen here, except the aspen. The buffalo berry, Lepargyrea argentea, conspicuous by its silver-gray foliage, is abundant, forming large clumps, and reaching the height of fifteen and even twenty feet. The thickets are composed of various willows, interspersed with some choke-cherry trees, Cerasus demissa, and dogwoods, Cornus stolonifera ; these supplemented by dense masses of Distegia involucrata reminding one of the hedges of so-called "buckbrush," Cephalanthus, bordering the banks of swampy lakes in Mississippi River bottoms. At this elevation the Distegia (the Lonicera involucrata of 4 PLANT.E BAKERIAN.E. some authors) attains the height of eight or ten feet; but up near the timber-line it is a dwarf of sometimes not more than one or two feet. The more conspicuous herbaceous plants of these thickets are Mertensia ciliata, Geranium Rich- ardsonii, a new species of buttercup, Ranunculus Earlei (Greene), and Polemonium filicinum, a species originally from southern New Mexico, and which here it may be assumed, reaches its northern limit of distribution. Among such as these were also gathered a few herbaceous plants, notably Carex aurea and Collomia lanceolata, and several more, which are more properly subalpine and alpine. And as we after- wards grew familiar with the whole region, including the higher elevations about the headwaters of this stream less than twenty miles away, the wonder constantly grew, not that only a few alpine or subalpine plants should occur in the. valley below, but that so few of these species had been able to adapt themselves to the condition of the lower levels even where the cool thickets furnished such excellent shade with abundant moisture, and the rapidly flowing stream offered such abundant facilities for the downward distribution of seeds. As a rule the Mancos specimens of species having a considerable altitudinal distribution' were taller and more slender than those subsequently taken in mountain mea- dows ; which variation seems attributable partly, at least, to their having grown in the shade. But in other cases, such as the Collomia and Carex aurea, the low elevation seemed to have had the opposite effect of dwarfing the plants ; speci- mens from about Mancos being much smaller than those taken at elevations greater by a thousand feet. Separated from the flood-plain by a steep bank five to fif- teen or even twemty feet high, and constituting a more elevated secondary bottom, the sage plain stretches away for a mile or more on either side of the valley to the foot- NARRATIVE. 5 hills. This tract, as I have said, has in part been reclaimed and brought under cultivation. Originally it was covered with low-growing gray-green chenopodiaceous and composite shrubs, such as constitute what is commonly called sage brush. Those portions not under cultivation exhibit these growths, intermixed with clumps of bushy Amelanchier and Peraphyllum representing the family of the Pomacese; and it also supports a peculiar and most interesting herbaceous flora, made up of Lupinus argenteus and other lupines, numerous species of Astragalus and other papilionacese, several Pentstemons and Castilleias, Allium acuminatum and Calochortus Gunnisonii representing the lily family. The pinon belt occupies the low foothills from 1 00 to 400 or 500 feet above the valley. Here Pinus edulis and Juni- perus monosperma combine in not unequal proportions to form a low scraggy woodland growth. Neither species often exceeds twenty feet in height, and each is frequently adorned by its own species of parasitic Razoumoffskia and Phoradendron. Herbage is scanty in this belt, and the her- baceous species quite characteristic, like Lescuriella Palmeri, Pentstemon linarioides, Astragalus scopulorum and Picradenia Richardsonii. Our belated Mississippian, Professor Tracy, arrived in the morning of June 26 and we started at once for the western flank of Mt. Hesperus, our wagon piled high with boxes of paper, presses, bundles of driers and camp equipage. Our plan was to make a somewhat permanent camp as near timber line as we could go with a wagon, and then to take time to thoroughly explore the country both above and below. Our road started due north from Mancos but soon bore northeast and followed up a rather narrow ridge or divide between the deep rocky canon of the West Mancos on the right, and Chicken Creek, a smaller tributary of the 6 PLANTS BAKERIAN^E. Mancos, on the left. About four miles from town, and at an elevation of some 7,500 feet, we left the piiions and the chaparral-covered hillsides through which we had been traveling, and came suddenly into magnificent open pine woods. Our driver told us that the lumbermen distin- guished two kinds of pine, but all seemed to be Pinus sco- pulorum the difference in the timber being probably due to differences in the age and condition of the trees. Many of the pines are of large size and the ground between them, while mostly clear of brushwood, yields a sufficient growth of grass and herbage to give it an attractive park-like effect. Though the collecting in this lower part of the pine belt was not specially interesting, it furnished a few charac- teristic plants, such as Lotus Wrightii and Lithospermum multiflorum. Advancing toward higher ground, the winding road brought us to an elevation of about 9,000 feet, where the pines give place to aspen thickets. At this point we ob- tained our first impression of the riches of vegetation belonging to the higher mountains; for the aspen thickets of limited extent were found to alternate with considerable stretches of native meadow brilliant with a great diversity of flowers blooming among the abundant grasses. Fields of the large sunflower-like Wyethia Arizonica, clumps of purple lupine bordering these, red Castilleias and white Polygonum bistbrtoides, Potentillas of several sorts along with other things as showy combined to form a beautiful and most inviting botanical landscape. Still continuing the gradual ascent, spruces (Picea Engel- mannii) began to intersperse themselves in groups among the aspen clumps, becoming gradually more and more pre- ponderant, until finally the aspens cease altogether at 11.000 eet, where the spruces thenceforward hold undisputed sway NARRATIVE. 7 up to the timber-line which, in this latitude, is at about 11,500 feet. Having made a late start, on this first day of the ascent, we covered only about fifteen miles, camping for the night near the head of Chicken Creek. A little beyond this point our road descended abruptly into the West Mancos Canon, thence following that stream up to Jackson's stamp mill, at the very base of Mt. Hesperus. The difficulty of getting our heavy outfit back out of this deep canon seemed so great that we decided to keep on up the ridge, following some old cattle and pack trails as far as it should prove practicable to take the wagon. We succeeded in getting three or four miles further, and made our second camp on the headwaters of a little tributary of the West Mancos locally known as Bob Creek. We had reached an elevation of 10,500 feet and were about two and a half miles due west of the main peak of Mt. Hesperus, but with the deep and rugged valley of Slide Rock Creek lying between. The laborious climb out of this valley with a heavy load of plants, after a day's collecting on Hesperus convinced us that we had made a mistake in not taking the lower road and so pitching our camp in the canon, when the home- ward trip would always have been down hill. The region above timber was reached in three different places from this Bob Creek camp, on the southwest face of the ridge between West Mancos and Slide Rock Creeks, which constitutes the westernmost spur of Mt. Hesperus, on the north face of the same ridge farther east near the head of Slide Rock Creek, and on the Bear Creek divide north- east of camp. In all these places the ground was rather dry and exposed. Many interesting plants were taken, but the full glory of the alpine vegetation was not seen till we 8 PLANTS BAKERIASLE. reached the moister basins at the head of the La Plata River on the eastern side of the range. One of the most interesting features of this western flank of the range was the great reaches of verdant mountain meadow stretching away in every direction between the scattered clumps of spruces and aspens. The grass, con- sisting largely of Poas and Festucas, was exceedingly luxuriant and was everywhere sprinkled or crowded by showy species of Mertensia, Polemonium, Valerianella, Frasera, Veratrum, Aconitum, Delphinium and numberless other smaller flowering plants. The morning of July 6 found us breaking camp and starting on the return trip to Mancos. The season was now at its height, and it was marvelous to see how rapidly vege- tation was developing at these high altitudes. Had time permitted we should gladly have lingered longer at this camp, for each day brought new species into bloom, and it seemed to our regretful eyes that we were leaving more still undeveloped species behind us than we had found in con- dition to collect. The trip back to Mancos occupied two days, as much time was consumed in collecting on the way the things that had opened during our brief absence. A further stop of two days in Mancos enabled us to pack and ship the dried plants that had accumulated, and to take a short side trip over the sage plains to the south west ward along the road toward Cortez, in the direction of the Ute Moun- tain. This day's collecting proved to be the richest in the number of specimens taken and in the number of new species of flowering plants discovered of any on the entire trip, thus showing that in planning future work in this region the lower levels should receive careful attention. The afternoon of July 9 found us again under way for a trip up the La Plata Valley on the east side of Mt. NARRATIVE. 9 Hesperus. Our route lay over some low divides through a rather uninteresting country, part of the time in oak chaparral, and at times getting up into the open pine belt. During the afternoon of July 10 we passed Dix P. 0. and reached the old mining camp of Parrott City at the foot of the mountains, just at the entrance to the canon of the La Plata River. Continuing a few miles further, we made camp in the bottom of the canon about two miles south of La Plata City. This was one of the richest spots visited. The bottom of the valley is only a few hundred yards wide, and it is walled in on either side by the pre- cipitous slopes of the mountains. It is very moist, and is filled with a luxuriant tangle of vegetation. Rubus Nutkanus here grows to perfection, and the ground is fairly carpeted with the showy Eyigeron coulteri and Penstemon glaucus stenosepalus. The gravel banks in the stream also furnished conspicuous and abundant species, including Epilobium latifolium and Senecio atratus. The elevation here was about 9,000 feet. On July 12 we again moved camp going toward the head of the valley. Above the town of La Plata the canon grows much narrower and the grade is much steeper. The road is soon forced to leave the stream and is cut into the hillside. For a considerable distance no suitable place for a camp could be found, but finally just below the mouth of Basin Creek, at about 10,000 feet elevation, a projecting ledge of rock gave us just room to put up the tent and get the wagon out of the road. Stakes being out of the question tent ropes were made fast to boulders, and our quarters, though re- stricted, proved sufficiently comfortable. Wagon roads have been constructed several miles farther to reach various stamp mills, but they were so rough and steep that we did not attempt to take our heavy outfit, beyond this 10 PLANTS BAKERIAN.E. point but made daily trips above timber line in various directions. The basins of the small streams far above timber line were here all veritable alpine gardens well stocked with Mertensias, Polemoniums, Trifoliums, Erigerons, Castilleias and many other showy alpine genera. Even the most rugged slopes exhibited a great diversity of species ; for every nook and crevice among the rocks where any soil had found a lodgment was filled with plants. On the very summit of Mt. Hayden at 13,000 feet we gathered excel- lent specimens of Trifolium nanum, Chionophila Jamcsii, Ligusticum Eastwoodix and Pentstemon Harbourii. It is to be noted that about three-fourths of the plants collected here were of species not represented at any of the lower altitudes. It was with much regret that on July 16 we took leave of this interesting locality and made our way to Durango. Each little sheltered slope and basin that we visited fur- nished some plant not seen elsewhere, and, had time per- mitted a thorough exploration of the region our list of species would have received many additions. Furthermore, the flowering season had not yet reached its fullness. Very many species were not yet beginning to bloom, and it was manifest that a month's sojourn would have enabled us to nearly double our collections. This Alpine research was disappointing in respect to only two groups of plants. Of ferns we took but two species, Cystopteris fragilis and Cryptogramme acrostichoides ; and the number of lichens was much smaller than had been antici- pated. The bare rocks supported a fair number of crusta- ceous species, which, owing to the early loss of our chisel, we were unable to collect; and terrestrial and arboreal species were very scarce. NARRATIVE. 11 Durango is a thriving town located in the valley of the Las Animas river at an elevation of 6,500 feet. South of the town the hills rise 1,000 or 1,500 feet higher. They are mostly composed of beds of shale with a few coal-bearing strata and so give but few plants of interest during the hot midsummer months, even along the narrow ravines and arroyas. The Grindelias, Mentzelias and Eriogonums found within the city limits proved fully as interesting as the plants of these nearby hills. In some places they sup- port a considerable growth of Juniperus monosperma with scattered trees of pinon. Near the eastern edge of the town one small hill was noticed that had been covered by a rather dense growth of this juniper, but now only a few of the trees were living, the others having apparently been killed by Gymnosporangium speciosum Peck, which had left the swollen and distorted trunks marked with its peculiar plicate tumors. North of town toward Trimble Springs the Animas valley is somewhat broader, though bounded on each side by pre- cipitous mountain walls which rise from 2,000 to 2,500 feet above the stream. Every acre of irrigable land is in a high state of cultivation, hay or green fields and orchards filling all the valley from Durango to where the Hermosa River joins the Animas. Here we noted similar willows to those found at Mancos and at the base of the cliffs were box elders and Eibes cereum. Through the kindness of Col. Thomas Hamor, of Durango, we were enabled to make a somewhat hasty trip to Colum- bine, twenty-five miles north of Durango, on the old Silverton trail, and only a few miles to the eastward of our Upper La Plata camp. The place is near the head of the valley, and Hamor's Lake, a picturesquely beautiful sheet of water, is one of the sources of the Las Animas river. The lake 12 PLANTS BAKERIAN.E. seems to have been formed by the sudden closing in of the canon wall so that though not large it is of great depth. It is as clear as crystal and even after our visit it still contains some magnificent trout. The elevation here is about 9,000 feet and the hills and wet meadows near the lake yielded a greater number of species than any other equal area that we visited. In the water of the lake itself was an abun- dance of Chara Hippuris and Potamogeton while on its borders were Thalidrum alpinum, Gentiana heterosepala,Swertia scopulina, Agastache wrticsefolia, Lilium montanum and many other species not taken elsewhere. Mr. Tracy, who was the last to arrive, remained in the neighborhood of Durango until July 28. Messrs. Earle and Baker departed on the 18th and 19th respectively, making about an even month in the field for each of the three members of the expedition. Perhaps the most striking impression gained by the trip, aside from that produced by the abundance and beauty of the high alpine flora, is that of the distinctness with which the different altitudinal floral zones are marked out and limited. It is true a few species were found all the way from the Mancos River bottoms at 7,000 feet to timber line at 11,500 feet, but these instances are rare. In the great majority of cases each species observed had an altitudinal range of not to exceed 1,000 feet, even with similar con- ditions of soil and moisture. In a general way these life zones seemed to be the same here as in the not far distant San Francisco Mountains of Arizona, where they have been so carefully studied by Dr. Merriam, of the U. S. Biological Survey. We could easily distinguish the pinon-cedar belt, the pine belt, the aspen-spruce belt and the timber line belt as designated by him, and we found this division a very useful one in the prosecution of our work. NARRATIVE. 13 While we endeavored to make our work as thorough as possible for the very limited region actually explored, we realize fully that it is only a beginning. The number of plants collected serves to illustrate the great floral richness of the region, and our experience suggests that for future work the higher mountains should be visited during the period from July 15 to September 1, when an almost entirely new set of plants would be in bloom; and that work in the lower levels, especially in the canon and mesa region south and west of Mancos is greatly needed earlier in the season, say from May 1 to June 15. It is hoped that at least some of our party may be able to continue the work another season. t I CATALOGUE. FUNGI. By S. M. TRACY and F. S. Among the more striking features of the fungus flora of the region which the collection represents may be men- tioned the great abundance of the Uredinales and Sphseriales. The Erysibacese would have been abundant later in the season, though only two species were found in condition to collect. Perisporacese were entirely lacking, as were also the Hysteriales, though the latter were persistently sought for everywhere. The Pezizales are represented by only two species. The Helvellales do not appear in the list, but fine specimens of Morchella and Gyromitra were observed in the high spruce woods. The Agaricacese are very scantily rep- resented in the list, but they were really quite abundant in moist locations at the higher altitudes. Lack of time and of facilities for properly drying the specimens prevented collecting them. Among the Sphssriales which constitute nearly a third of all the species collected, and of which con- siderably over one-half proved to be undescribed, the almost entire absence of such common eastern genera as Hypoxylon and Valsa is to be noted, as well as the great abundance of Lophiostomatdcese, a family rarely found by eastern col- lectors. The Dothideales and Hypocreales are each repre- sented by a single species only. It is interesting to note that of the entire collection only the following five species were taken above timber line: Schizonella melogramma, Puccinia acrophila, P. Claytoniatum, P. Pimpinelldz and Patinella Crandallii. . The smallness of this list is to be accounted for in great part by the fact that our BAKERIAN^;, Vol. I. Pages 1-53, Feb. 22, 1901. 92102 (15) 16 PLANTS BAKERIAN.E. time above timber line was always limited and that the beauty and abundance of the flowering plants claimed our attention, to the neglect of the Fungi. In the following list the sequence of families is that of Engler & Prantl. In the few cases in which the generic name used by us is another than that employed by Saccardo in the Sylloge Fungorum, the latter is added in parenthesis. PERONOSPORACE^E.

HERPOTRICHIA NIGRA Hartig Hedw. xxvii. 13. On living leaves of Picea Engelmannii, Bear Creek Divide, 11,000 feet, June 29, n. 232. This has not before been reported from America. The asci soon vanish, and at full maturity the ascospores are fuliginous. In our specimens the perithecia often reach 5mm. In other respects it closely agrees with the descrip- tion given by Hartig. It was also observed on Mt. Hes- perus near timber line, but was not seen below H',000 feet. This was previously collected by C. F. Baker on spruce in northern Colorado, July 13, 1896, at Cameron Pass, 10,000 feet, and distributed by him under the name of Lasiosphdsria Coulteri, Peck. It closely resembles that pine-inhabiting species externally, but the spores are entirely different. ROSELLINIA PARASITICA Ell. & Ev. Proc. Phil. Acad. 28 PLANTS BAKERIAN.E. 1890, p. 227.

Our specimens agree so closely with published descriptions, especially with that in Winter ii, that we so name them, but we have not seen European specimens. ZIGNOELLA POTENTILL.E n. sp. Perithecia scattered, erumpent becoming superficial, black, depressed globose, roughened, Jmm in diameter; ostiolum conical; asci cylin- drical or fusiform, short stipitate, 8 spored, 45-50xlO-12/x; paraphyses filaforrn, longer than the asci ; ascospores hyaline, oval or elliptical, faintly f -septate, ll-12x4-5//,.

On dead twigs of SymphoricarpuSj Bob Creek, 10,500 feet, June 27, n. 173, with Rosellinia parasitica and Strickeria Sym- phoricarpi. The true generic position of this species is somewhat doubtful. Its scanty imperfect stroma suggests that it should be placed in the Cucurbitariacege rather than in Mellogramma, but the vestiture of the perithecia would exclude it from Gibberidia, as that genus is now denned. Since perithecial hairs are present in the nearly related Gibbera, from which our species is excluded by the spore characters, we prefer to widen the definition of Gibberidia rather than to propose a new genus based only on the pres- ence of perithecial hairs. OTTHIA DISTEGI^E n. sp.

VOLUME II. FASCICLE I. KTJNGI TO Price, Forty Cents. INTRODUCTORY. Mr. Baker's ample and most interesting collection of the year 1899 was made, as his own brief and pointed Itinerary will indicate, along the borders of southwestern Colorado and adjacent New Mexico. The field was one wisely selected, as the large proportion of new plants obtained suf- ficiently declares; while the great extent of the collection shows how vast an amount of travelling and of other physi- cal labor the zeal and industry of one strong and vigorous young man can accomplish in a single season, and as it were single handed. Our report upon this rich and beautiful collection will constitute Volume II of the PLANTS BAKERIAN^E. The material has, at this date, for the most part been quite care- fully studied, and it is hoped that at intervals not widely separated the succeeding instalments of the volume may reach the hands of the subscribers to the sets. Inasmuch as this second volume will inevitably catalogue many species that were reported in the first volume, the names of such as are, as it were, duplicated in the collection of 1899, will be printed in italics here, only such being ex- cepted as were published as new in the first volume. The names of these will be given in the usual small capital type. EDW. L. GREENE. Catholic University of America, Washington, D. 0., 11 March, 1901. 94151 ITINERARY. By CARI, F. BAKER. The first camp of 1899 was established early in March at Hermosa, Colorado, at about 6,700 feet altitude, in the upper Animas Valley and on the west slope of the Needle Moun- tains. At this time, alder and the first willows were in bloom, and a few days later the first Cymopterus appeared. A few unopened flower buds of Townsendia sericea were also seen. During this month special attention was given to mosses, lichens and fungi, with good results. By April 1 Pulsatilla began to bloom. On April 10 the second camp was made on the banks of the San Juan River, just below the town of Aztec, New Mexico, at an altitude of about 5,500 feet. This region is characterized by sand hills and gravelly mesas, sparingly covered with pinon pine and cedars, the whole very, very dry. The hills along the extreme southern border of Colo- rado do not differ essentially in many places from the Aztec hills, and the distance is not great. Undoubtedly most of the plants found at Aztec will also be found in Colorado. Many things were coming into bloom when camp was made at Aztec. During the month it was found that a very re- markable and evanescent flora existed among these hills. This flora appears during the very earliest warm days of spring. The plants arise from perennial bases, flower and fruit very rapidly, and have passed before hardly any of the plants usually considered so characteristic of the region are in their prime. Of most things, specimens were few and scattering. Miles and miles of the interminable pinon hills were tramped over to secure enough for issuance. On many of the days, the cold northwest winds were extremely bitter. IV PLANTS BAKERIAN^E. The statement that all plants in the '99 sets from this locality were taken during April or the first few days in May has seemed surprising, even to those best acquainted with collecting in the southwest. Summer and fail collect- ing in this locality would unquestionably give very inter- esting results. During the early days of May camp was moved far up the valley of the Rio de los Pinos to the lower end of Gra- ham's Park at an altitude of 7,800 feet. Here the results of a cold, dry spring were very evident, and collecting was poor. On the 15th of the month camp was moved down the valley to Los Pinos P. 0. (also known as Bayfield) on the same river, at about 7,000 feet altitude. This place is just north of the Ute Reservation line, and on the zonal division between Pinus edulis (pinon) and Pinus ponderosa. Here were still further signs of drought. Collecting was n ecessarily largely confined to the river bottoms and ground moistened by seepage from irrigating ditches. On June 1 camp was moved to Arboles, in the river bot- tom at the junction of the Rio San Juan and Rio Piedra, only a few miles above the New Mexican border. Collections were made here and also at Rosa, New Mexico. Numerous large flocks of sheep were rapidly devastating the narrow bottoms. The destruction could scarcely have been more complete had the work been done by fire. A number of very interesting plants were found among the very dry sandy hills and along the stony mesa banks, among them a new Coleosanthus, two new Astragali, and a new Carduus. As at Aztec, these hills are covered sparsely with pinon, pine and cedar, though otherwise the two localities are very distinct. The next move made was up the Rio Piedra to Piedra ITINERARY. V P. 0., at about 7,000 feet altitude and well within the Pinus ponder osa zone. As will be seen from the Colorado Forestry Commission map, this zone curves strongly to the southeast, east of Durango, following the trend of the San Juan range. The road up the Piedra valley is new and extremely rough. An entire lack of bridges necessitated fording the river many times. Frequently the wagon wheels became wedged among the boulders of the river bed, com- pelling the carrying out of the entire load through the ice cold waters, by hand. Habenaria hyperborea was unex- pectedly found about a cool spring in a dark shady gulch near Piedra and a new Cypripedium at the same place. During the last of July a move was made to Pagosa Springs (at about 7,100 feet) over a good road passing through magnificent forests of Pinus ponderosa. The end of these forests is in sight, their destruction being actively under way now. The desolation caused by the lumberman and the fires which follow in his wake, is an evidence of an appalling lack of foresight, not possible in the more scienti- fically enlightened countries. In a favorable year Pagosa Springs would unquestionably be the most promising head- quarters in southwestern Colorado for mountain botanizing. It is the center of a wonderful region, man} r distinct topo- graphical areas being readily accessible. The unusually fine hot springs at this place attract many tourists through the season. Above this point are some of the finest natural meadows in the State. Under ordinary circumstances, at this season of the year there is still much snow on the sur- rounding mountains. But in 1899 none could be seen and the terrible drought was at its height. Sheep and cattle were hurried up from the lower levels, though many died of hunger and thirst. The most striking plant at this point was Rhamnus Smithii. VI PLANTS BAKERIAN^E. About August 1 another move was made over a road just built for mining purposes to Camp Loraine, in a narrow basin between Pagosa Peak and Saddle Mountain, at an altitude of about 9,000 feet. This whole basin is richly watered by small streams, but sheep and drought together had, during 1899, devastated the above-timber country. From this basin as a base, expeditions by foot were made for many miles about, over the surrounding mountains, an elevation of 12,500 feet being reached at several points. The results from above timber were very disappointing, though as full advantage as possible was taken of the richer vegetation below. Below timber line these mountains are richly clothed with magnificent forests of spruce principally Picea Engelmannii. Deer and bear were abundant here and mountain lion frequent. Black grouse could also be had at any time. At this time should be acknowledged many kindnesses received from a very affable and whole-hearted gentleman, Mr. W. R. Black, of Pagosa Springs, part owner of the promising Baritone Wonder and Omaha mines near Camp Loraine. He gave freely all the needed information as to trails, topography, meteorology, and all similar matters. Camp at this point was regretfully broken up on August 30. A ten days' stop at Chama, New Mexico, completed the season's work. During this ten days a trip was made up on Cumbres Pass, where an elevation of 10,000 feet was reached. But the sheep had been there first. The collecting was done throughout by one person. It would have been entirely possible to have accomplished far more had the season and other conditions been more favor- able. Whatever success was attained was due in no small measure to the faithful services of the camp-hand, an Ala- bama negro from Prof. Earle's station force. This man's ITINERARY. Vll very unusual value lay not so much in his great strength and endurance, as in the fact that he would do exactly as told. Throughout the field work constant reference was made to the very useful and minutely exact topographical maps lately issued by the Geological Survey, as well as to those of the Hay den Survey. Mention should also be made of the very interesting and valuable though not wholly cor- rect map in the Biennial Report of the Forest Commissioner of the State of Colorado for the years 1887 and 1888. CATALOGUE. FUNGI. By F. S. EARI,E. By the subjoined enumeration it will be seen that Mr- Baker's collection of 1899 is rich in new species of Ascomy" cetes, in this regard surpassing the collection made by Baker, Earle and Tracy in the same general region in the year 1898. The present list of species would have been more extensive had not much of the material collected on dead stems of herbaceous plants in early spring proven im- mature and thereby indeterminable. Those of the same habitat gathered in August, and even in July, were for the most part in good condition. This is especiall}< true of species belonging to the Mycospserellacese, and the Pleo- sporaceae. Specimens belonging to those families in which the perithecia on hard-carbonaceous, such as the Amphi- sphseracise and Lophiostomatacese, usually contained recog- nizable asci and spores which had been found the year before, but were not in satisfactory condition. Thanks are due to Dr. J. C. Arthur for aid in connection with the Uredinales ; to Dr. L. M. Underwood for determin- ing the species of Polyporus, and to Mr. David Griffiths for careful cultural studies of the Sordariacese. USTILAGINACE^:. USTILAGO CARICIS, Fckl. Symb. 39.

Ascocarps thickly scattered, at first buried, becoming erumpent or subfree, closely sessile, dark brown, almost black, coriaceous, cup shaped, about J-lmm., the epithecium at first covered by a membrane that soon splits stellately into about 20 marginal teeth that are erect, exposing the epithecium when moist but closed down over it when dry; epithecium dark brown; asci 50-60x5/>t, cylindric-clavate, embedded in the numerous paraphyses that unite above in a well marked epithecium; ascospores distichous or inordinate, spindle shaped, hyaline, somewhat unequally uniseptate, 8-10x2-3/x. On dead weather-worn twigs of Fendlera rupicola, Her- mosa, Colo., April 4, (no number given. E. L. G.). TRYBLIDIOPSIS OCCIDENTALIS, n. sp. Ascocarps scattered, at first buried, then prominently emergent and almost free, sessile, black, dull, somewhat rugose, long closed, at length irregularly or stellately dehiscent exposing the dark brown disc, from \ 1mm. in diameter; asci broadly oval, thick walled, about 100x25-30/w.; paraphyses greenish, much ex- ceeding the asci, branched and interwoven above into a dense epithecium ; tips scarcely swollen ; ascospores broadly oval, ends rounded, uniseptate, at first hyaline and sur- rounded by a gelatinous envelope that is thickest at the septum, finally loosing this coating and becoming dark brown and somewhat constricted, about 30xl8/A. On the smooth bark of dead twigs of Junip&rus, Hermosa, Colo., April 3. This is the first species of this well marked genus to be detected in this country. TRYBLIDIUM OCCIDENTALE, n. sp. Gregarious, often crowded; ascocarps Patellaria-like, at first somewhat sunken in the matrix, then free, black, subrugose, about Jmm. 94152 10 PLANTS BAKERIAXJS. wide, flat, sessile, long closed but finally exposing the orbi- cular, rugose, dull black disc, margin inconspicuous; asci 80-100x20/x, thick walled; paraphyses numerous, thread like, united above in a thick epithecium; ascospores dis- tichous, ovoid, ends obtuse, about 5 septate, somewhat con- stricted, part or all of the cells longitudinally divided, hya- line or probably at length brownish, about 30xlO/x. Common on decorticated twigs of Amelancliier, Cercocarpus, Qaercus (n. 14), Rhus, and Salix (n. 15), Hermosa, Colo. March and April, 1899. Often associated with Lophium leptothecum and Melaspilea emergens. Issued as Blitridium rhois n. sp. HYSTERIACE.E. HYSTEROGRAPHIUM BAKERI, n. sp.

FUNGI. 1 1 LOPHIUM LEPTOTHECUM, ii. sp. Scattered or gregarious: ascocarps erect, elongate, compressed, the base sunken in the wood fibers, black, brittle, carbonaceous, roughened by transverse striations, black and shining within, lips thin, closely compressed, l-ljmm. high, about Jmm. broad with the sides nearly parallel or slightly tapering upward, about Jmm thick ; asei numerous, very long, 400-500x6/x; para- physes abundant, threadlike, very slender, less than 1/a thick, not conspicuously branched ; ascospores dark-brown equalling the ascus, about 2/x, thick, conspicuously and closely septate, the cells 2-3/* long, when freed from the ascus usually breaking into pieces, 12-16 feet long. On barkless dead twigs of Amelanchier (n. 83), and Quer- cus and Rhus (n. 84) at Hermosa, Colo., March. Ellis records doubtfully three species of this genus as occurring in North America. The first seems to have been a case of mistaken identification ; and of the twoSchweinitzian species he is un- able to give any account of the asci and spores. JThis new one seems therefore to be the first fully authentic member of this genus to be found in America. ERYSIPHACE^E. ERYSIPHE POLYGONI, DC. Fl. Fr. ii. 273.

Specimens in the main at agreement with other western ones that have FUNGI. 13 been referred here; but the asci are only 60-80x6/*, and the ascospores 8-10x4-5//, which is smaller than the measure- ments usually given. In Durango specimens on oak, and others from Hermosa, the perithecia are superficial, or nearly so, but seem partially buried by the fine fibrous shreds of the weather-worn wood. ROSELLINIA SUBCOMPRESSA, Ell. & Ev.? Bull. Torr. Club, xxiv. 177. On barkless wood of poplar, at Hermosa, 1 April; n. 65. In the absence of authentic specimens for comparison these are so named with some doubt, though they agree with the short description given. CUCURBITARIACE.E. CUCURBITARIA BERBERiDis, S. F. Gray, Nat. Arr. i. 519. Durango, 19 March, on dead twigs of Berberis Fendleri. OTTHIA CLEMATITIS, n. sp. Perithecia crowded or occa- sionally scattered, dull-black, carbonaceous, rugulose, about J mm. in diameter, ostiole perforate, slightly sunken, seated on a thin crust-like black stroma that remains after the breaking down of the perithecia, developing under the cuti- cle but exposed by its rupturing and breaking away, by con- fluence sometimes forming linear masses several cm. in length; asci paraphysate, subcylindric, 90-1 20x1 6-20/x; ascospores inordinate, oval, ends subacute, slightly con- stricted, often somewhat curved, about equally uniseptate, light brown, about 40x8/*. On dead and decaying bark of Clematis ligusticifolia, Du- rango, 19 March; n. 41. Most of this material is too old The species should be collected in autumn. On some stems the perithecia are mostly scattered so that it might be taken for a Didymosphseria. In other cases they are densely cespi- tose and seated on an evident stroma. 14 PLANTS BAKERIAN.E. OTTHIA FENDLERAECOLA, n. sp. Perithecia buried, then partially erumpent, densely crowded in one or two rows and bursting through the bark in long linear masses, 6 or 8 to 20 or more together, often flattened by mutual pressure, dark brownish black, conspicuously rugose, large, J-f mm., ostioles, perforate, depressed; asci cylindric, about 100xl8/x; paraphyses thread like; ascospores monostichous or partly distichous, light brown, fusiform, ends acutish, uniseptate, not constricted, about 25x6/x. On dead and dry but not barkless twigs of Fendlera, at Hermosa, 4 April; n. 42. OTTHIA DISTEGLE, Tracy & Earle, PI. Baker, i. 29.

Perithecia. scattered or somewhat gregarious, black, smooth, thin walled, strongly collapsing, about J mm, ostioles indistinctly perforate, not prominent; asci clavate-cylindric, about 100xl6/x; paraphyses thread like, abundant; ascospores subdistichous, irregularly oval, often curved, 5-7-septate, one or more of the medial cells once vertically divided, constricted at the middle septum and often slightly so at the others, somewhat flat- tened, about 30-35x10x7^. On decorticated twigs of Amelanchier, Hermosa, Colo., 30 March; n. 69. This is much like S. Fendlerse externally, but it has very different spores. STRICKERIA CERCOCARPI, n. sp. Blackening the wood ; perithecia with the base sunk in the matrix, scattered or cespitose in clusters of 3 or 4, black, rugose, not shining, a FUNGI. 15 length slightly collapsing above, about Jmm., ostiole mi- nutely papillate, rather inconspicuous; asci cylindric, short stiped, about lOOxlO/*; paraph yses very numerous, thread like, exceeding the asci; ascospores monostichous, oval to ovate, dark brown, at length 7-septate, with most of the cells once or twice vertically divided, constricted at the middle septum, ends often somewhat unequal, obtuse or subacute, 20-25x8/4. On old decorticated branches of Cercocarpus, at Hermosa 28 March. STRICKERIA FENDLER^E, n. sp. Perithecia scattered or gregarious, black, shining, thin walled, collapsing to patel- loid, 200-300/t; asci cylindric, thick walled, 80-100x20/1 ; paraphyses thread like, abundant; ascospores distichous, oblong, ends obtusely rounded, 4 septate, one or more medial cells vertically divided, hyaline, at length very light brown, 25-30x10^. On barkless weather-worn twigs of Fendlera rupicola, Hermosa, 4 April. This species is well marked by the strongly collapsed perithecia that look like a minute saucer-shaped Patellaria and by the nearly hyaline spores. STRICKERIA POPULI, n.sp. Perithecia scattered, black, shin- ing, the largest Jmm. in diameter, subglobose, at length slightly collapsed or indented above, ostioles simply perforate; asci about 80xl6/x,; ascospores monostichous, at first yellowish and uniseptate, becoming brown and 3-septate, constricted at each septum, one or both medial cells vertically divided, ends obtuse, about 18-20x8-10. On decorticated, weathered twigs of Populus angustifolia, Durango, 21 March ; n. 68. This is near S. insecura, but differs in the shining, par- 16 PLANTS BAKERIAN.E. tially collapsing perithecia and in the smaller asci and spores. The spores do not seem in any case to be more than 3-septate while in the latter species they are often 5- and even 7-septate as seen in N. A. F. n. 882 and in Baker, Earle & Tracy, n. 1059. STRICKERIA RHOINA, n. sp. Perithecia thickly scattered, bases deeply buried, dull black, J-f mm., at length collapsing, ostioles minutely papillate, often obscure ; asci cylindric, short-stipitate, about 100-120xl(V ; paraphyses numerous, thread-like, exceeding the asci ; ascospores strictly mono- stichous, ovate, yellow or light-brown, at first 3-4-septate, becoming 5-7 -septate, one or more medial cells once verti- cally divided, slightly constricted at the middle septum, about 20x8ft. On decorticated wood of Rhus trilobata, Hermosa, March 29. The asci and spores are much as in Teichospora rhy- podes on Rhus from Michigan, but the perithecia are twice the diameter, strongly collapsing, and lack the " conic-papil- liform " ostiolum of that species. STRICKERIA, sp. On decorticated Salix, Hermosa, March 28. The specimens are too old for satisfactory identifica- tion. The spores are 7-septate, 35xl5/x. STRICKERIA, sp. On Quercus.

Perithecia scat- tered or somewhat closely gregarious in small groups, black, shining, carbonaceous, nearly spherical but the top slightly flattened, not collapsing, about Jmm., ostiole minutely papillate ; asci clavate, 70-80x8-10^ ; paraphyses numer- ous, filiform, yellowish ; ascospores distichous, light-brown, somewhat fusiform, often curved, 2-4-septate, somewhat constricted at the septa, 16-20x4-5/x. FUNGI. 17 On decorticated stems of some Chrysothamnus, Hermosa, 4 April; n. 70. TREMATOSPH.ERIA FENDLERJS, n. sp. Scattered or grega- rious on more or less blackened areas; perithecia prominent, conic-mammellate, dark brownish black, roughened toward the base, carbonaceous, not collapsing, Jmm. or more in both height and diameter; asci subcylindric, thin- walled, about 60-80xl8/u ; paraphyses abundant, filiform ; ascospores normally distichous but often obliquely monostichous or inordinate, narrowly oval, somewhat curved, dark-brown, 3-septate, scarcely constricted, about 20-25x6/4. On decorticated twigs of Fendlera; same place and date as the last. TREMATOSPH.ERIA LUPINI, n. sp. Perithecia scattered, black, carbonaceous, free, with base slightly sunken, spheri- cal or somewhat vertically elongated, about -Jmm., ostiole scarcely papillate, perforate, the top of the perithecium finally breaking in but not collapsing; asci numerous, clavate-cylindric, short-stipitate, about 80x8/4 ; paraphyses filiform, abundant; ascospores distichous or inordinate, slender, pointed, light brown, 5-7-septate, 30-40x4/4.

Perithecia scattered, elongate, about Ixjmm., rough, dull-black, the base often clothed by clinging wood fibres, ostioles inconspicuous, at length opening by a crack or chink; asci cylindric, short- stipitate, 100-1 40x1 2/z; paraphyses filiform, abundant; ascospores ovoid, 3-septate, constricted at middle septum, ends somewhat unequal, one or both medial cells once ver- tically divided, light-brown, becoming dark-brown and opaque at full maturity, about 20x10^. On decorticated Amelanchier, Hermosa, 30 March; n. 75; also on Fendlera, Hermosa, 4 April. PLATYSTOMUM SALICUM, n. sp. Perithecia scattered, at first buried then emergent, black, shining, elongate, f-lmin. long by about half as wide, ostioles perforate, usually slightly sunken, longer than wide; asci clavate,, thick- walled, 80-100xl6/>t; paraphyses abundant, filiform; ascospores subdistichous, 5- or occasionally 7-septate, slightly con- stricted at middle septum, ends subacute, often curved, one or two cells vertically divided, the divided cells usually somewhat enlarged, light-brown, at length dark and opaque, 30-35x7-8 p. On dead barkless willow twigs at Hermosa, 30 March. SCHIZOSTOMA CERCOCARPI, n. sp. Developing under the bark which falls away, exposing extensive black crust-like areas; perithecia oval, about Jxjmm., black, scarcely shining, densely crowded, often a little confluent, seated on a thin black stromatic crust, ostioles inconspicuous consist- ing of an obscure compressed ridge extending for three- fourths the length of the perithecium; asci linear-cylindric, abundantly paraphysate, about 80x6/*; ascospores mono- FUNGI. 19 stichous, fusiform, uniseptate, constricted, light olivaceous brown, about 16-18x4/4.

Perithecia aggre- gated on irregular blackened spots, nearly spherical, black, 100-150, ostioles inconspicuous, seated on irregularly anas- tainosing mycelial threads beneath the epidermis and coming away with it; asci aparaphysate, clavate, clustered, 40-60x6-8/4; ascospores distichous, narrowly oval, ends acutish, hyaline, uniseptate, not constricted, about 12x3/4. On dead stems of Delphinium, near Pagosa Peak, 10,000 feet, 29 Aug.; n. 37. MYCOSPHYERELLA PENTSTEMONis, n. sp. Perithecia rather densely aggregated on irregular blackened areas, black, nearly spherical, of coarse cellular structure, about 150-200/4 in diameter, seated on a brown, much branched, frequently septate mycelium of very large brown threads 10-12/4 thick, the branches slenderer; asci aparaphysate, clustered, clav- ate, about 60x12/4; ascospores distichous or inordinate, ovate, hyaline, often guttate, unequally uniseptate, con- stricted, about 25x6/4.

On dead lupine stems, Hermosa, 4 April ; n. 82. This seems to be sufficiently distinct from any of the many species attributed to papilionaceous hosts. LEPTOSPH^RIA TYPH^E Karst. (?) Myc. Fenn. ii. 99. On dead stems of Typha, at Hermosa, 30 March ; n. 33. This differs materially from all other specimens of Lepto- sphseria found on Typha in this country in the decidedly smaller spores and narrower asci. Our specimens have the asci about 60xl2/x and the spores only 20x5/-t, while in specimens of L. typharum (Desm.) Karst. the asci are 60-80x20/4, and the spores 25-30x7-8/4. Our measurements of perithecia asci and spores agree closely with those pub- lished for L. Typhse, but in our specimens the perithecia are often densely cespitose in clusters of 6 or 8 to 20 forming double or single lines and not "scattered" as described for the European specimens.

On dead twigs of Chrysothamnus, at Durango, 21 March; n. 34. This striking fungus can hardly belong in the genus Macrosporium. Its compact growth suggests the Tubercu- lariacise rather than the Dematiacese. The only recognized genus of the former family with muriform spores is Spegaz- zinia, but our fungus differs widely from that genus in habit and in that the corridia are not borne on sterigmata but on the ends of the sporophores.

This is easily distinguished from T. Sambucina by the larger softer sporodoche, the larger thicker conidiophores and the much larger conidia. In specimens of the latter species examined from Europe and from Wisconsin the conidia are only 5-6x1 J/^. TUBERCULARIA, sp. ? On dead branches of oak, Hermosa' 30 March; n. 74. This is a very peculiar fungus. The large 2-3mm. sporo- doches swarm with motile bacteria-like bodies. The coni- diophores seem to be only 8-12xl/n and variously branched or united. The conidia are about 2-3xl/u. It is externally brown, but vermilion-red within, and crumbling to a red powder. It suggests the red stroma of some Endothia-like fungus rather than a Tubercularia, but no perithecia could be detected. LICHENES. By T. A. WIWJAMS. Cladonia fimbriata, Fr.

There is perhaps no section of the Middle West which presents more interesting or important agrostological prob- lems than does this field of our 1899 explorations and researches. The pasturage is almost everywhere here most excellent ; and even the alpine grassy slopes of vast extent far above the limit of trees are converted into a sheep pas- ture. And the still richer Piedra Meadows are famed throughout the whole southern Rocky Mountain region. The less elevated and more arid parts of the country have also their own grass flora of much importance, and this sec- tion in particular calls for careful investigation and experi- mentation in relation to the preservation and propagation of its forage plants. In the determination of the species of the following list, invaluable service has been rendered by Mr. F. L. Scribner, to whom a set of specimens was sent for identification, and by the late Mr. T. A. Williams. Later Mr. C. L. Shear furn- ished some important additions and corrections. The bibliographic citations and one or more alterations in nomenclature have been supplied by Dr. Greene. The somewhat extensive field notes are my own. CARL F. BAKER. PANICUM CAPILLARE, Linn. Sp. 58. In stony dry river bed at Piedra, Colo., 14 July. GRAMINE.E. 35 HIEROCHLOE ODORATA, Wahlenb. Fl.

My botanical field work in the Rocky Mountain region, begun nine years since, will be continued in 1901 and 1902, with better facilities and under conditions otherwise more promising than heretofore. The speci- mens will be of better quality. The determinations will be made by those botanists who are most competent to deal with matter from the West; thus making the collections authoritative, as representing in herbaria the flora of the several regions explored. In 1901, the summer and autumn will be given to the field from Mar- shall Pass eastward and south westward to the boundary lines of Colorado; a field, as far as known, exhibiting many peculiarites as to plant genera and species, and therefore of the highest promise. The ground will be covered as carefully as possible, at all elevations, *. e. y from 4,000 to 13,500 feet. This will be our third and probably the concluding series of our Colorado plants. It is purposed to begin, in 1902, the exploration of a still newer field, that of the more westerly State of Nevada ; and several years may be devoted to that field, prosecuting the work throughout many of its isolated and almost or altogether unexplored mountain ranges, and to the western and southern borders of the State. Subscriptions to all these series are now being received, and should be registered as early as possible ; for the sets go out to subscribers in the order of time recorded for the subscription, the fullest sets to the earliest subscribers. Arrangements have been made whereby it will be possible for any institution to obtain these sets. Correspondence is solicited. A few short sets of the collections by Baker, Barle and Tracy in 1898 are still available. One good set of the 1899 collection, but lacking the grasses, sedges and rushes, though very rich in the new species, remains unsold. Its price is $73. The distribution of mosses and liverworts from South America will soon be made. These include many new species. Address . C. F. BAKKR, Normal and High School, St. I^ouis, Missouri, U. S. A.

ITINERARY. ITINERARY. Plans for the summer months of 1901 embraced an ex- amination of the flora of the Gunuisori watershed, includ- ing the region from Marshall Pass to Grand Junction, with the valleys and hills adjoining the Gunnison River and its principal tributaries. This region has a northwest and southeast extension in west central Colorado and includes areas of very diverse character, both topographical and geological, and the flora varies accordingly. The drainage area is a part of that of the Colorado River and its waters eventually reach the Gulf of California. The region is separable into three distinct areas: The High Mountain Area, the Foothill Area, and the Desert Area. On the extreme east lies Mount Ouray and its com- panion peaks; to the north the Elk Mountains of numerous very high and often jagged peaks, and to the south the Cochetopa Mountains less lofty and more often with rounded, grassy summits. The above, with that portion of the San Miguel Mountains about the headwaters of the Uncompahgre River, a tributary of the Gunnison, and the Grand Mesa, compose the High Mountain Area of this region. All that country between Jack's Cabin, Sargent's and- Lake City on the one hand, to Cerro Summit and Ridg- way on the other, may be classed as Foothill Area. This is a country of comparatively low, rounded hills and narrow valleys, the hills covered with sage brush and scattering pine and spruce, the valleys with alder, willow and cotton- wood along the streams, and with frequent rich meadows. Passing down the Gunnison, the river just below Sapinero 777-1 11 PLANTS BAKERIAN.E. enters the rocky gorge of the Black Canon. This is passa- ble for the Rio Grande Railroad for fifteen miles to a point near Cimarron, where the Cimarron River enters from the south. Here the railroad is compelled to climb up through Cimarron Canon and over Cerro Summit to seek a western outlet by way of the Uncompahgre Valley to Delta, which is again on the Gunnison. From Cimarron to near Delta the Gunnison runs through its Grand Canon, so deep and narrow and with such precipitous walls as to be quite inaccessible. Passing westward from Cerro Summit, the change in character of country and of flora is one of the most sudden and most remarkable in the State of Colorado. Cerro Sum- mit is a huge hill covered with thickets of oak scrub and Amelanchier (scattering other shrubs) and supplied with a rich herbaceous vegetation. A few miles to the westward and a few hundred feet below, say at Cedar Creek, one is in the Desert Area, with cedars, pifion, Sarcobatus, Atriplex, and a characteristic desert flora. From this point to the west end of the Grand Mesa, the broad Uncompahgre Valley was originally almost an utter desert. It is flanked on either side with adobe hills or gravelly mesas, sparingly clothed with cedars or entirely naked, the bottoms with Sarcobatus and its companions, and along the stream willows and cotton woods. From Delta to Grand Junction the Gunnison runs through its Lower Canon which is broader and shallower than the Grand Canon and flanked by barren and broken sandstone hills, in some places closely resembling the Colo- rado Canon formation. A collection of the curious flora of this hot, dry Lower Canon was made within seven miles of Deer Run. At Grand Junction the Gunnison passes into the broad valley of the Grand River, which is also desert ITINERARY. Ill where unirrigated. Below Grand Junction the lowest alti- tude in the State is reached. In the High Mountain and Foothill* Areas the rocks are quite largely metamorphic and the soils are constituted accordingly. In the Elk Mountains near Crested Butte and Ruby there are extensive outcroppings of slate and coal. In these mountains collections were made at Crested Butte, Rogers, Keblar Pass and Ruby. The Elk Mountains are a wonderful range of high, closely set, jagged peaks, well watered, richly clothed with spruce forests and other vegetation undoubtedly richer in this respect than any other mountains of Colorado. They are remote, rarely visited, and together form the richest and most promising high-mountain botanical field in the State. Deep forests, meadows, open glades and parks, dripping cliffs, and springs and streams everywhere, altogether furnish a most remarkable field for plants of all groups. Later on when our Botanical Gardens and Universities establish their substations for Experimental Ecology and similar work, there should certainly be one here. In the High Mountain, Area collections were also made at and near Marshall Pass, at Carson in the Cochetopas, at Ouray and on the surrounding hills in the San Miguels, and on the summit of the Grand Mesa. In the Foothill Area, collections were made at Jack's Cabin, Sargent's, Doyle's, Gunnison, lola, Sapinero, the Black Canon, Cimarron, at Van Boxle's Ranch above Cirnar- ron, on Poverty Ridge near Cimarron, on the Black Mesa at the head of Crystal Creek, and on Cerro Summit. In the Desert Area collections were made at Cedar Creek, Montrose, Cedar Edge, Deer Run, and Grand Junction. * This term may be objected to as not equivalent to the Foothills on the east slope. But neither would the Desert Area hei^ be equivalent to the Plains on the east. IV PLANTS BAKERIAN.E. While the localities given are not many in number, still, around them and between them a good deal of ground was covered. Tramps were made around each point for a radius of several miles and most places were visited more than once during the three months. Walks were also made be- tween Ruby and Keblar Pass, between Keblar Pass and Crested Butte (seven miles), between Crested Butte and Jack's Cabin (fifteen miles), between Marshall Pass (alt. 10,800 ft.) and the top of Mount Ouray (14,000 ft.), and to the top of Little Ouray, between Lake City (8,000 ft.) and Carson (11,500 ft.) and return (thirty-two miles), between Cimarron and top of Poverty Ridge and return (ten miles) three times, between Cimarron and the Black Mesa and re- turn (sixteen miles), four times between Cimarron and Cerro Summit (five miles), through the fifteen miles of the Black Canon three times, from Cerro Summit to Cedar Creek (seven miles) from Grand Mesa Lakes to Cedar Edge (seven miles), from Telluride to Ouray (twenty miles, over a divide rising to 13,500 ft.), and between Deer Run and Kanah Creek (seven miles) three times. This is over and above the local work around all the points mentioned. So the plants obtained will represent the phanerogamic flora fairly well. Getting into the field so late and doing all the work alone made it impossible to give the necessary attention to the collection of the cryptogams. But the region is rich in them. The fleshy forms were noted especially in the Elk Mountains, where they were abundant even up into the highest timber. Such fungi and mosses as intruded them- selves on the attention were collected. Two points in the subalpine country should be especially noted the Grand Mesa and Van Boxle's Ranch. The Grand Mesa is a high elongated plateau extending north- westerly from the West Elk Mountains to the Gunnison ITINERARY. V below Delta. It is a remarkable place. The top is well watered, with many streams and beautiful lakes and with rich forests and open parks. About the base lies the desert. The Grand Mesa can be readily reached by a twenty-five mile drive from Delta. Van Boxle's Ranch is twelve miles above Cimarron on the headwaters of the Little Cimarron. One could scarcely find a richer or more beautiful mountain locality than this, surely not one more remote or less known. Splendid trout fishing is not one of the least of the many attractions. Here should be detailed those plants which were observed but for various reasons were not collected. The high spruce woods were composed almost entirely of Picea Englemanni and Pseudolsuga. Along the lower border of the spruce are extensive thickets of quaking aspen, some of the trees often reaching very good size. Here, also, in favorable places bear berry (Arctostaphylos uva-ursi) is common. Through- out the foothill and mountain country Alnus was frequent along the streams, and the red-berried Sambucus was occa- sional in the higher altitudes. The scrub oak thickets so common in the foothill country have already been men- tioned. Wet swales in the lower altitudes were usually filled with Typha, and often contained colonies of Scirpus occidentalis. One of the poison oaks (Rhus) was common in the bottoms throughout the lower altitudes, but ex- treme susceptibility, induced by a most troublesome expe- rience in the swamps near Mobile, Alabama, led me to give it a wide berth. Again cattle were seen browsing it, apparently with relish. Helianthus petiolaris, Plantago major, Salsola kali, Solanum nigrum, Xanthium strumarium, Amarantus blitoides, and A. retroflexus, occurred on almost all cultivated areas, along roads and railroads, and in rail- road yards. In the Gunnison Valley the Russian Thistle VI PLANTS BAK BRIANS is almost entirely confined as yet to the yards and along the right of way of the railroad. The section men have instructions to destroy it, but it was found that few of them were acquainted with it. In its younger states it is soft and succulent, and cattle and horses eat it freely. Humulus lupulus occurs occasionally in the bottoms, and a few plants of Panicum crus-galli were seen at Grand Junction. Cereus phoeniceus and one of the ordinary yellow-flowered prickly pears are common throughout the foothill country. On gravelly hillsides in the Desert Area, Opuntia arborescens is not uncommon. Phleum alpinum and Poa alpina were abundant throughout the alpine region. A few immature plants of Melica bulbosa were seen on Poverty Ridge. Above Ouray a few plants of Artemisia franserioides were observed. The agricultural possibilities of this region as it is de- scribed above would not appear very promising. On the contrary, they are very great. Even the naked adobe soil possesses a wonderful fertility and requires but water to make it yield richly. Even now there are ranches where small ditches could be taken out, all along the Gunnison except in the narrow canons, and likewise along the Un- compahgre. Near Crested Butte (8,878 ft.) the altitude is too great for common garden vegetables and fruits, but the natural meadows in the vicinity, full of native grasses and sedges, have been improved and produce heavily. At Jack's Cabin (about 8,300 ft), fifteen miles below Crested Butte one may see beautiful fields of alfalfa and timothy, and here are raised radish and lettuce and other very hardy and quickly maturing garden vegetables. Sargent's (between Gunnison and Marshall Pass) is much like Jack's Cabin in this respect. Doyle's, between Guunison and Sargent, was found to be a very interesting locality on account of the considerable per- centage of alkali in the bottom's soil. The meadows here ITINERARY. Vll were consequently not as rich and were overrun with the worthless, even injurious, grass locally known as "fox-tail." A number of distinctly halophytic plants were present such as Trigloclin maritima and a Plantago. At Guiinison (7,680 ft.) are some beautiftili ^eacjpws, though many are filled with a most astonishihg arra^of native plants. When these are in bloom;, thfc 1 ]riger^nfe,\ Pedicularis, Castilleias, Crepis and many others, present a very beautiful sight. Barley, oats and red clover do well here, and better examples of radish, lettuce, carrots, turnips, potatoes, rhubarb, cabbage, etc., would be hard to find. It is probable that some of the small fruits would prove a great success at this point. Coming down out of the foothill country and entering the desert above Montrose, one finds beautiful orchards and broad green fields where the ground has been irrigated, and portions now have the appearance of a prosperous agricul- tural district. It is,' however, near Delta (about 5,000 ft.) and neighboring towns that the fruits are grown to greatest perfection. Here are produced pears, peaches, apples, plums, cherries and other fruits which cannot be excelled. Grand Junction is also the center of a great fruit country. There is, in this Gunnison region, a vast natural supply of water from the high mountains and vast areas of land which that water may yet be carried to in ditches, so that the possibilities before the region are almost unlimited. The day is coming when the lower Gunnison valley, now largely a desert, will be one of the richest agricultural re- gions in the United States. Thousands of sheep are pastured during summer in the lower foothills. Higher up many cattle may be found, though there is rich unoccupied range for many times the number now there. Vlll PLANTS BAKERIAN^E. The field work, all done between June 1st and September 1st by one person, resulted in the collection of above 25,000 specimens with notes on each species. Also, photographs were taken of all the characteristic ecological associations. As r ip ^previous years the work would have been largely impossible put /or the co-operation and encouragement of ,J)r.; 15.; L. ^Greene, whose remarkable knowledge of the American field directed operations in these most remote localities, even to definite hills, valleys and meadows. Here also should' be acknowledged the great kindness of Mr. E. T. Jeffery, President of the D. & R. G. System, and of other officials of the Road, without whose assistance some of the work would have been quite impossible. A faithful boy, Ed. Dundin, did the camp work, and most of the changing of driers, though the work of first, putting plants into press, taking out those finally dried, cleaning, bundling, writing labels and separating a study set, necessarily de- volved on the collector. CARL F. BAKER. Stanford University, California. 15 Oct., 1901. RANUNCULACE.E. EXPLANATORY. Mr. Bakers' botanical exploration of the Gunnison Water- shed in the summer, of 1901, has already proven a remarkable success, both as to the number and quality of the specimens; while the wealth of new species is even greater, I think, than was obtained in other sections of southern Colorado either by Mr. Baker in 1899, or by Baker, Earle and Tracy in 1898. Many of the new things in those two earlier collections are still unpublished; this being largely due to my having undertaken to publish full lists of those collec- tions, and in due taxonomic sequence. Pending the completion of volumes I and II of the PLANTS BAKERIAN.E, I propose giving, as a first instalment of volume III a somewhat miscellaneous congeries of paragraphs dealing with new or otherwise interesting species; in this absolving myself from the obligation more fanciful than real of following any particular sequence of Families. Any difficulty which this want of order may seem to entail upon students of the sets, will be obviated by an index to the genera treated, if not even to the species. EDW. L. GREENE. Catholic University of America. 21 Oct., 1901. RANUNCULACK^e. RANUNCULUS EREMOGENES, Greene, Eryth. iv. 121. Abundant in a small pond within the Black Canon, n. 204; quite typical. In publishing this interesting analogue of BAKERIAN^;, Vol. III. Pages i to 36. Nov. 18, 1901. 7772 2 PLANTS BAKERIAM;. the Old World R. sceleratus, I credited it to no station more southerly than middle Colorado. The present record would therefore be a considerable extension of its range. But my herbarium shows that I myself collected it in 1889 as far south as Trinidad, on the extreme southern verge of Colo- rado. Mr. Heller has more recently distributed it from Rio Arriba Co., New Mexico; and I may here note that in 1898 I found plenty of it along the muddy margin of a lake in southern Minnesota not far from Windom, this being its most easterly habitat so far as known. RANUNCULUS EREMOGENES, var. PILOSULUS. Much smaller than the type, with several subequal ascending stems 5 or 6 inches high; herbage of a deeper green and sparsely pilose-pubescent; receptacle, heads and achenes much as in the type, but all smaller. In damp places above Gunnison, 17 July, n. 454. Quite different, except as to height and mode of growth, from my var. degener of the same species. RANUNCULUS PURSHII, Richardson. Fine large speci- mens, growing in ponds near Gunnison, n. 669; differing from the high-northern type in failing to show the very narrowly dissected submersed leaves. A so-called "R Pur- shii" of Mr. Baker's collecting at Fort Collins, Colo., in 1896 is clearly R. eremogenes. RANUNCULUS UNGUICULATUS, Greene, Pitt. iv. 142. Two numbers of this, both from the Grand Mesa; 228, much smaller than the type specimens and too young; 234 is more mature, and large enough to represent the species well. RANUNCULUS OREOGENES. Of the size and habit of R. ellip- ticus, with even larger and coarser roots, but foliage of dif- RANUNCULACE^E. 3 ferent form and texture, being much firmer and scarcely ucculent, the lowest leaves narrowly ovate-lanceolate, those next succeeding them linear-elliptical, the blades about 1J inches long, the petioles about as long, the mostly solitary cauline like the others but closely sessile, all vivid-green and reticulate-venulose above, pale beneath, even whitish, all perfectly entire; scapiform peduncles decumbent, simple and 1-flowered, or with one or two 1-flowered branches: calyx and corolla not seen: head of achenes ovate; achenes pubescent, the body suborbicular, the beak rather prominent? curved. At Cerro Summit above Cimarron, 7 June, n. 50; occur- ing on open hillsides, but past flowering. In addition to the above, the collection exhibits the following less noteworthy Ranunculi: R. reptans, Linn., n. 464; R. inamoenus, Greene, nn. 235, 350; R. Macounii, Britt., n. 562, and R. Macauleyi, Gray, n. 319. BATRACHIUM TRICHOPHYLLUM, Bossch., n. 320. CYRTORHYNCHA RUPESTRIS. Stems very slender and few- flowered, more than a foot high; biternate foliage ample and of more than half the height of the stems; flowers mostly only 5 or 6, on long slender pedicels and very small: petals about 5, variable, some obovate and sessile, others (transitional to stamens) with smaller blade and long claw: achenes few, short and of almost elliptic outline, the ribs prominent, but more or less confluent and inclined to form narrow reticulations. On moist cliffs in the Black Canon, 20 June, n. 198. An excellent new species of an interesting genus, this has the aspect of C. neglecta, of northern Colorado, but not at all either its flowers or fruits. 4 PLANTS BAKERIAN^E. CALTHA CHIONOPHILA, Greene, Pitt. iv. 80. Two repre- sentations of this; n. 227, from the Grand Mesa, shows con- stricted but not dentate foliage, while n. 408, from Carson, has the leaves smaller, more rounded, and notably dentate. TROLLIUS ALBIFLORUS, Rydb. Fl. Mont. 152. Under n. 221 we have excellent flowering specimens of this fine plant which Mr. Rydberg has well separated altogether, in name and rank, from T. laxus. DELPHINIUM NELSONII, Greene. On open hillsides at Cerro, n. 52, the usual form; n. 216, the largest and most showy specimens yet seen, said to be abundant in open parks at Van Boxle's, abo.ve.Cimarron. DELPHINIUM DUMETORUM. Near the last, but more slender and commonly 2 feet high or more; leaves remote and with fewer and broader segments; herbage glabrous; ramifications of the root more slender and disconnected: flowers smaller and less widely expanding, though with ispur longer and more slender, acutish and strongly curved downward at the end, the color of the whole flower a pale lavender-blue: follicles puberulent, shorter and more widely spreading than in D. Nelsonii On dry hills, among shrubbery above Cimarron, 6 June, n. 35; growing quite apart from D. Nelsonii, which occupies open grassy ground at higher elevations. DELPHINIUM QUERCETORUM. Resembling D. glaucum, perhaps as tall, with equally leafy stem and narrow con- densed raceme; herbage pale and glaucescent, but only the stem and petioles truly glabrous, the leaves villous-puber- ulent, their 3 to 5 segments broad -cuneiform and 3-lobed, not toothed ; rachis of the spike strongly hirtellous, the pedicels CRUCIFEM;. 5 most so, and the hairs of these viscid and mostly gland- tipped: small flowers very dark blue-purple, the sepals rugu- lose and together with the slender-conical turgid straight ascending spur rather rough-hairy : ovaries densely villous. Common among oaks at Cerro, 12 July, n. 412. At first glance this appears much like true D. glaucum, though the leaves are much less divided than is usual in that species, and the flowers are much darker ; but a lens reveals the abundant short-hairiness of the foliage ; and the even stronger pubescence of the rachis is of a character quite peculiar. Moreover, this is a dry-land plant, whereas D. glaucum, grows only in wet places. ACONITUM BAKERI. Stern stoutish, erect, simple and rather strict, 2 feet high, the whole upper portion of the plant, even to the flowers, villous hirsute with brownish hairs, some of them gland-tipped : lower parts glabrous, the lowest leaves 5-parted and the cuneate divisions doubly about 3-cleft : raceme compact: hood f inch high, the gal- eate portion rounded, scarcely higher than broad, much shorter than the downward portion, the beak broadly subu- late, projecting horizontally; follicles about 4, glabrous. At 10,000 feet near Marshall Pass, 19 July ; said to be common in wet places.' The only American species with dense almost spicate and strict inflorescence, the sepals and petals remarkably pubescent. It is the only Aconite of this year's collection. CRUCIFER.E. DRABA GRAMTNEA. Perennial, the much branched stems 3 to 5 inches high, the older portions thickly clothed with long dry chaffy remains of the leaves of other seasons : leaves of the season linear and grassy, almost as long as the 6 PLANTS BAKERIAN.E. short-peduncled loose and rather few-flowered racemes, glabrous above the middle, but below it loosely ciliate with simple hairs : sepals yellow ; petals pale-yellow : filaments abruptly and widely dilated at base; young pods ovate, acute, surmounted by a conspicuous style, few-ovuled. A most remarkably chaffy and grassy-looking Draba of alpine habitat, found near Carson, 2 July, n. 296. Its near- est affinity would seem to be D. chrysantha. DRABA OXYLOBA. Perennial, tufted, the several and quite simple flowering stems or branches decumbent, leafy to near the middle, thence racemose, 8 to 18 inches high; foliage and stem not at all canescent, scarcely even pale, nevertheless roughened everywhere by an sparse indument of sessile and uniformly 4- parted hairs: basal leaves 1 to 2 inches long, oblanceolate, petiolate, remotely dentate or else entire, the petioles, at least near the base, with a few scattered marginal simple and setaceous hairs; cauline leaves ovate to oblong-lanceolate, commonly hear an inch long, sessile, dentate: sepals and petals both golden-yellow, the former with scattered short mostly simple (rarely forked) hairs: pods not twisted, oblong-linear to elliptical, 4 or 5 lines long, acute at each end, pointed with a style of less than one line ; pedicels slightly ascending, longer than the pods. At Van Boxles' Ranch above Cimarron, in open parks, n. 382 ; also at Sargents, in meadows, n. 351 ; distin- guished from all its allies by a pubescence of cruciform hairs. DRABA BAKERI. Rather slender yellow-flowered per- ennial, the several erect stems 4 to 10 inches high: tufted radical leaves about an inch long, oblanceolate, short-petio- late, entire, acutish, cinereous, at least when young, with CEUCIFER^E. 7 stellate pubescence, the stem and inflorescence greener, the pubescence more sparse, mostly of forked or 3 -branched hairs, but with some much longer and perfectly simple ones interspersed: cauline leaves lanceolate, serrate-toothed, ses- sile: fruiting raceme loose, with leafy bracts subtending the lower pedicels : flowers small; sepals green, notably bristly- hairy at apex; petals yellow, scarcely twice the length of the sepals: pods erect, short-pedicellate, narrowly elliptical, pubescent on the face with more or less forked and appressed hairs, but the margins quite hirsutulous with mostly simple ones: style short. Near the limit of trees, in the mountains near Carson, n. 316. An ally of D. streptocarpa, the pods doubtless more or less twisted when mature. ^ . r . , r DRABA NITIDA. Annual, very erect and strict^ simple. ctt; with a few shorter racemes from near the base, the whole plant often 10 to 14 inches high, racemose almost from the base, and, except at base, glabrous, deep-green and shining: leaves in a comparatively small radical tuft, the longest barely an inch long, oblong-lanceolate, obtuse, entire, the outer narrowed at base but hardly petiolate, sparsely sub- stellate-pubescerit, the margins loosely bristly-ciliate; cauline few, oblong-ovate, entire, sessile : pedicels 3 or 4 lines long, ascending, the oblong-linear acutish often somewhat in- curved glabrous pods about as long: flowers small, yellow, the green sepals more or less pilose, as is also the base of the stem: style none. Abundant on moist open ground at 10,000 feet above Marshall Pass, 19 July, n. 492. A less luxuriant state of the same was collected, also by Mr. Baker at Cameron Pass, northern Colorado, at 9,800 feet, in July, 1896. The plant is one which has been referred erroneously to D. stenoloba. 8 PLANTS BAKERIAN.E. ARABIS DEMISSA. Low and slender, the racemose steins or peduncles only 5 to 8 inches high, but the caudex large in comparison, stout and lignescent, not .branched, or the branches not obvious, bearing a dense tuft of very narrowly oblanceolate glaucescent leaves, which are' glabrous except for a few setose hairs on the margin at the base of the pe- tiolar portion: peduncles several, with 2 or 3 subauriculate sessile bracts below the raceme, this (seen in fruit only) loose, the purplish and glaucous pods narrowly linear, 1 to 1J inches long, deflexed on very short pedicels: seeds in one row, suborbicular, not winged, though with more than the hint of a scarious margin on at least one side. A few specimens of this interesting and strongly charac- terized; new; species were gathered from among the stones of a dry 'river bed near Cimarron, 4 June. They bear the jariYnbie? 1fr,;'of .the collection, but are not in quantity for distribution in the sets. ARABIS STENOLOBA. SufTrutescent as to the branching caudex, the slender flowering stems less than a foot high, tufted basal leaves and those of sterile branches of the caudex oblanceolate, entire, less than an inch long, both faces hoary with a minute stellate tomentum : floriferous branches with scattered small leaves below the raceme, this short and few-flowered ; sepals purplish, stellate-pubescent, as are also the pedicels and the stems, petals white, twice the length of the sepals: pods very narrowly linear, 1 to 1J inches long, obtuse, glabrous, suberect on almost filiform pedicels of J to J inch. On stony hillsides above Cimarron, n. 21. Plant with much the habits and foliage of A. eremophila, but the pubes- cence different, the fruit more so. THELYPODIUM BAKERI. Biennial, with several widely VIOLACE^E. 9 divergent stems from amid the tuft of spreading basal leaves; herbage glabrous, except some hirsute hairiness at base of stem, and very glaucous : radical leaves petiolate, cauline numerous, narrowly cordate-ovate, sessile and clasp- ing, entire, an inch longer more: flowers white, the greenish sepals somewhat spreading, the petals with broad claw and spreading spatulate-obovate limbs : spreading pedicels of the pod very slender, the pod itself narrow, not stipitate, an inch long or more. Stony hillsides at Cimarron, 6 June, n. 32. This is a very near ally of Miss Eastwood's T. aureum, but its flowers are white, and the pods are not stipitate. THELYPODIUM LILACINUM. Biennial, two or three feet high with rather many ascending branches from near the base, all racemose at the end; herbage deep-green and glabrous; basal leaves 2 or 3 inches long, spatulate-oblong, entire or repand, cauline reduced, lanceolate to nearly linear: flowers corymbosely crowded, but the raceme lengthened in fruit to 4 or 5 inches; sepals erect, rich lilac-purple, of less than half the length of the spatulate-linear petals, these at first white but soon changing to the lilac of the sepals: pods slender, torulose, 1J inches long, scarcely stipitate, slender- beaked. At Doyle's, n. 635. Related to T. integrifolium, but of dif- ferent habit, with different inflore.scen.ee, and peculiarly handsome flowers. VIOLACE^:. Only the genus Viola is represented; but that in an inter- esting array of species by far the greater number of which are absolutely new. V. CANADENSIS, Linn., n. 383. 777-3 10 PLANTS BAKERIAN,E. V. RETROSCABRA, Greene, Pitt. iv. 290, very recently pub- lished, is represented by the two numbers 68, 144, both from near Cimarron. This and the three new ones next succeeding are of the natural group represented by the Old World V. canina. V. STENANTHA. A multiciptal and csespitose dwarf, form- ing mats 2 or 3 inches broad, little more than 1 inch high ; herbage very minutely and sparingly scabro-puberulent, the angles of the petioles more obviously and retrorsely so : leaves deltoid-ovate to oval, little more than J inch long, rather fleshy, lightly crenate, usually tapering, though abruptly, to the petiole: peduncles about equalling the leaves, bearing conspicuous subulate-linear bractlets near the flower, sepals large for the flower, oblong-linear, acute, glabrous, not scarious-naargined: corolla dark-blue, about 5 lines long including the very long and narrow somewhat hooked spur, very narrow, the petals not widely expanding, the keel broad j the others narrow. On the Grand Mesa, 23 June, n. 230. A species very well characterized by its long and narrow long-spurred dark-blue corolla. V. DEMISSA. Scarcely larger than the last, but rhizoma- tous, the rootstocks chaffy with the persistent sere and brown stipules of a preceding year: leaves J inch long, on petioles of about an inch, round-ovate to deltoid-ovate and oval, crenate, glabrous: peduncles much exceeding the leaves, bibracteolate towards the middle: sepals oblong- linear, asute; corolla nearly J inch long including the long obtuse cylindric spur, the petals subequal, widely ex- panding, violet above the middle, white below, and marked with purple veins. In moist grassy depressions at 12,000 feet above Marshall VIOLACE^;. 11 Pass, 19 July, n. 501. What is probably the same alpine or subalpine violet was collected by Mr. Baker at Cameron Pass in northern Colorado, as long ago as 1896. It is also represented in C. S. Sheldon's n. 277, obtained at Berthoud Pass in middle Colorado, 16 Aug., 1884. V. INAMCENA. Slender, glabrous, or the peduncles and petioles obscurely and retrosely hirtellous; stems several from the slender roots, but not much developed, often 1 or 2 inches long, greatly surpassed by the petioles and leaves, the plant thus appearing almost acaulescent: leaves round- ovate, obtuse, notably cucullate, lightly crenate; stipules subulate-linear, lacerately subpinnatifid: flowers seemingly always, even the earliest, short-pedunculate and apetalous, the small ovoid capsules deflexed. In low meadows along the river at Gunnison, 25 July, n. 603. The species seems nearly related to V. retroscabra, though the leaves are not only glabrous but more rounded and cucullate, while in the apetalous character of the flowers, and in form of the fruit, it connects with V. physa- lodes. I also provisionally refer here a plant collected by Mr. Baker at Cameron Pass, northern Colorado, 15 July, 1896, though its leaves are less rounded and not cucullate. The three species next succeeding are of the yellow- flowered group of caulescent violets. V. GOMPHOPETALA. Allied to F. Nuttallii, the crown of the root-bearing few and very short depressed leafy and floriferous branches; the whole plant light-green, with ciliate leaves, and their veins pubescent: leaves from round- ovate in the earliest, to oval and oblong-oval or oval-lanceo- late, the longest 1 J inches long, somewhat repand-denticulate or su ben tire, marked underneath by fine light almost par- allel veins or nerves, the petiole as long as the blade, slightly 12 PLANTS BAKERIAN.E. winged above: peduncles 3 inches long, surpassing the leaves: sepals linear-lanceolate, acute, glabrous: corolla about f inch wide, of rounded circumscription, the petals cuneate-obovate, very obtuse or almost truncate at the broad apex, all brown without, yellow within. On open hillsides of the Grand Mesa, 23 June, n. 225. V. PHYSALODES. Low, slender, the foliage very thin and the whole plant glabrous, sparsely leafy ascending stems well developed, 2 or 3 inches long, short-jointed and with a flower in each axil: leaves from subcordate-ovate to oval, obtuse, almost or quite entire, f to 1J inches long, obviously veiny only beneath; pedicels barely an inch long in fruit, slender, deflexed: flowers minute, apparently always apeta- lous; pods also very short, subglobose or obovoid. In thickets along the Cimarron River, 7 June, 1901, n. 67. The least showy, but by far the most interesting violet of all those which it has fallen to my lot to describe as new. The whole plant by its thin entire glabrous leaves, and numerous fruiting pedicels, always deflected beneath the leaves, give the species a singular likeness to some possible small Physalis. Though seeming to be altogether apetalous, I nevertheless see in it a member of that yellow- flowered group, of which V. NuttoMii is typical. V. BITEBNATA. Leafy stem not well developed at first, only 1 or 2 inches long, but subradical leaves very long-petioled, upright, 5 or 6 inches high, the peduncles of the few and early petaliferous flowers about as long: leaves very ample, palrnately or sometimes subpinnately biternate, the primary divisions broadly cuneiform, deeply trifid and their segments coarsely and deeply tridentate, all the segments and teeth obtuse, the margins ciliolate and veins pubescent with short bristly appressed hairs: corolla f inch broad, all the petals POLYGONACE^E. 13 obovate, obtuse, brown without, yellow within, the keel nearly twice the width of the others: small apetalous flowers many along the at length well developed stem, the capsules succeeding these large, round-obovid, on deflexed pedicels 1 or 2 inches long. Related to V. Sheltonii of the far Northwest, but very dif- ferent. The specimens, from two localities, collected in June, 1901, are numbered 42 and 233. POLYGONACE.E. POLYGONUM MONTANUM. P. Douglasii, var. latifolium, Greene, Bull. Calif. Acad. i. 125. P. Douglasii, var. mon- tanum, Small, Polyg. 118. Low, fastigiately branched from the base, 3 to 6 inches high, the banches floriferous from the base, but the flowers few among the proper leaves, most of them forming a mere bracted spike beyond the foliage, all the angles of stem and branches denticulate-scaberulous, and other parts also more or less scabro-puberulent : leaves oblong-lanceolate, very acute, often an inch long, 1-nerved, the nerve sharply carinate beneath the leaf: fruiting perianth subsessile but nodding, its segments dark green or purplish except marginally and completely enclosing the achene, this black, smooth and shining, the faces obtusely rhomboid al, the cross-section 3-lobed rather than triangular. The above description is drawn from a series of specimens collected by Mr. Baker this year at Marshall Pass, 20 Aug., and to be distributed under n. 893. These specimens represent perfectly what I had in mind when naming P. Douglasii, var. latifolium. But in the lapse of sixteen years, other things have become confused with this in my own and other herbaria, some of which are now to be segregated. Habitally, as well as in its general dimensions, P. montanum much more nearly approaches P. Austinse than P. Douglasii ; 14 PLANTS BAKERIAN^E. and in this, as well as in a few but very constant characters it may well claim specific rank. P. COMMIXTUM. Near the last but dwarf, 2 or 3 inches high, more herbaceous and with even ampler and more co- pious leafiness, the bracted spikes very short and dense; leaves and stem glabrous, the former from oval and even rhombic-ovate to oblong, mostly obtuse but with an abrupt sharp point, the midvein conspicuous, some secondary veins more or less obvious as diverging from it : perianths green, their segments with white or purplish margins, more widely expanding in flower and more loosely investing the longer and partly protruding achene, this more elongated than in the last in proportion to its thickness, dark and shining. The only specimens known to me of this are of Mr. Baker's collecting as long ago as 1896 in northern Colorado. One sheet is from Grizzly Creek, 24 Aug., the other from Cameron Pass, 10,000 feet alt., 13 Aug., both called by him P. Douglassii latifolium. The most notable characteristic is the narrow and partly exserted achene. This, with the dwarf stature, broad venulose leaves, and he excessive leafiness, seem to mark it as a good subspecies. 1 *A study of the above Bakerian plants has lead to the detection of another new species nearly allied, namely : P. HOWEI.UI. Sparingly branched from the base, but the few branches quite erect and contiguous, almost equably leafy to the summit and sparsely floriferous throughout, more scabrellous than P. montanum on all the angles ; herbage of a paler and rather yellowish green : elliptic- oblong leaves very acute, thinnish and not inclined to be revolute, their thin margins serrulate-scabrous : ocrese more scarious and almost fim- briate : perianths few, erect both before and after flowering, though not sessile : achenes wholly included and closely invested, very black and highly polished, the face rhombic-ovate, i. e., broadest, and rather abruptly so, much below the middle. Known to me only from Mr. Howells' specimens taken in the Siskiyou Mountains, northern Cali- fornia, 8 July, 1887, and distributed for P. Douglasii latifolium. POLYGONACE^. 15 RUMEX BAKERI. A yard high, the stems solitary or sev- eral, from a deep-seated taproot parted below into coarse fleshy-fibrous branches and with some more slender ones radiating around the crown of the main root: leaves, thin, glabrous, the basal ones with lanceolate-cordate blade 8 or 10 inches long on a petiole nearly as long, the cauline lance- linear, short-petiolate, those of the long and rather narrow panicle linear-acuminate, subsessile, 3 or 4 inches long, de- flexed: fruit small (barely two lines wide), deltoid-suborbicu- lar, very obtuse, grainless, delicately (but under a lens very distinctly) pinnate-veined, the veins running into a distinct favose reticulation toward the margin, but the margin itself thin, nerveless, either entire or obscurely somewhat crenate. Common in wet meadows about Gunnison, 22 August, n. 903, seeming related to R. polyrhizus of the more north- erly mountains. ERIOGONUM CHLORANTHUM. Near E. flavum, but more widely cespitose, the many branches of the caudex relatively much more elongated and densely invested throughout with the remains of the foliage of former years; leaves much thinner, spatulate-oblong, obtuse, hoary-tomentose beneath, glabrate above, nearly 1 J inches long : scapiform peduncles both slender and short, little surpassing the leaves, or even scarcely equalling them : involucres solitary, many-flowered, the flowers rather large, the cluster almost f inch broad: perianths greenish-yellow, the segments equal, the tube villous, acute at base but not stipitate. On stony alpine slopes of Mi Ouray, forming large mats, 20 August, h. 853. ERIOGONUM BAKERI. Allied to E. flavum, rather taller, 16 PLANTS BAKERIAN^E. the branches of the caudex very slender and only loosely leafy, the leaves thin, the elliptic-lanceolate blades J to 1 inch long, on slender petioles much longer, white- tomentose beneath, sparsely villous above: scapiform peduncles 5 to 8 inches high, erect, slender; inflorescence of a sessile involucre and 1 to 3 dichotomous peduncles from its base, the whole number of involucres thus 7 to 9, all turbinate: perianths yellow, small, very long-stipitate, silky villous, the inner segments much longer than the outer, all obovate, obtuse. Black Canon, 1 Aug., n. 696. Said to be cespitose in rather small tufts. The inflorescence is like that of E. Jamesii, though far less ample; and the real affinity is with E. flavum. ERIOGONUM SALICINUM. Allied to E. microthecum and E. Simpsonii, the tufted woody stems and long corymbose panicled peduncles together more than a foot high: blade of leaf lanceolate or oblong-lanceolate, about 1 J inches long, the petiole little more than \ inch, stem and lower face of leaves white-tomentose, surface glabrate: the long peduncles perfectly glabrous and very glaucous: corymbose panicles loose, diffuse, 8 to 10 inches broad: involucres very numer- ous, small and few-flowered, broadly turbinate or subcam- panulate, 5-toothed, the teeth erect, woolly within: perianths less than a line long, segments oblong, obtuse, white. Habitat of the last; n. 375. The species would not easily be distinguished from E. Simpsonii but by its broad and short thin leaves. ASCLEPIADACE^E AND APOCYNACE.E. ASCEPIAS SPECIOSA, Torr. Grand Junction, 11 June, n. 251. APOCYNACEJE. 17 ASCLEPIAS HALLII, Gray. Excellent specimens of a plant that is rare; obtained at Gunnison, 25 July, n. 595. APOCYNUM AMBIGENS. Intermediate between A. andro- ssemifolium of the East and A. pumilum of the Pacific slope; smaller than the former, more erect and more copiously floriferous, the corollas larger but still campanulate; follicles much shorter and thicker. In the Black Canon, 20 June, n. 202; also at Rogers', 14 Aug., n. 799. The plant is frequent in several parts of Colorado, and has passed for A. androssemifolium; but both this and A. pumilum are better accepted as fair geographical subspecies. APOCYNUM CANNABINUM, Linn. In moist ground on Deer Run, 10 June, n. 80. APOCYNUM LIVIDUM. Several feet high, with the pale and glaucescent hue of A. cannabinum, but the oblong- ovate mucronate leaves much larger and more spreading- inflorescence consisting, as in that species, of terminal and naked cymes, but flowers few, large and nodding, of a pale flesh-color; sepals thin and whitish, triangular-lanceolate, erect, half as long as the corolla, this campanulate, rather deeply cleft and with spreading or recurved segments. Common on railway embankments in Black Canon, 8 July. The plant recalls the Californian A. floribundum, but differs in having few and large flowers rather than almost innumerable small ones. ASPERIFOLI^. MERTENSIA CONGESTA. Tufted stems a foot high or less, stout and rather succulent, ascending; whole herbage of a 7774 1 8 PLANTS BAKERI AN^E. light and rather vivid green and, to the unaided eye seem- ing glabrous: leaves many and ample, from elongated-ovate to broadly oblong, obtuse, or some even retuse, the cauline sessile, the radical short-petioled, all 2 to 3 inches long, minutely and sparsely strigose above, glabrous beneath: flowers many, mostly in a single condensed terminal cluster, those of the few subterminal branches similarly crowded, the pedicels very short: calyx deeply cleft into ovate acute or broadly lanceolate segments, these strongly hirsute- ciliate and, in maturity, traversed by a very prominent light-colored mid vein: corolla deep-blue, about 4 lines long, the cylindric tube and campanulate limb about equal: nutlets acutely ovate, brown when mature and indistinctly sinuate-rugulose. On Poverty Ridge, near Cimarron, 13 June, in open parks, n. 129; also at Cerro Summit, a smaller plant, n. 62. /^ MERTENSIA LATERIFLORA. Stems tufted, rather strict and very leafy, a foot high or more, the whole plant canescently silky-strigulose: leaves almost crowded on the stem from base to summit, oblong-linear, acutish, about 3 inches long: short cymose flower-clusters in all the -axils from near the middle of the stem, on pedicels of about an inch long, the lower not equalling, the uppermost little surpassing the leaves: calyx small, completely divided into short-lanceolate scarcely acute segments, these strongly appressed-villous and ciliate: corolla of a light-blue, small, hardly 4 lines long, the limb only distinctly shorter than the tube. Said to be common at 9,000 feet, above Carson, where it forms large clusters, in flower 2 July, n. 334. Species cer- tainly resembling M. linearis, but a much larger plant than that, and with smaller flowers, the pubescence, however, being totally different. The inflorescence is peculiarly long, narrow and secund. ASPERIFbLI^J. 19 MERTENSIA CYNOGLOSSOIDES. Stems depressed, 1J feet long, sparsely and very amply leafy, the herbage delicate in texture and of a vivid green: lowest leaves oblong, obtuse, 4 or 5 inches long, on slender petioles of equal length, the cauline ovate-lanceolate, acutish, sessile by a subcordate-clasping base, these also 3 or 4 inches long and spreading, all very thin, glabrous beneath, sparsely but strongly scabrous above and scabrous-ciliolate: racemes few and sparse, long-peduncled, the upper part of the peduncle and the pedicels sparsely setose-hispid: sepals small, lanceo- late and ovate-lanceolate, obtusish, hispid-ciliolate, other- wise glabrous: corolla light-blue, almost funnelform, the short and rather broad tube quite exceeded in length by the campanulate limb into which it gradually passes: nut- lets white (perhaps immature), ovate, incurved at summit, turgidly and very irregularly rugose. On moist ledges in the Black Canon, 20 June, n. 191. A remarkably distinct species. MERTENSIA MURICULATA. Of the size of the last, nearly, and like it almost prostrate, but of firm texture and glau- cescent: lowest leaves elliptical, the blade 3 or 4 inches long, the petiole shorter; cauline ovate and lance-ovate, 1J to 2J inches long, sessile and partly clasping, all finely dotted above with white pustules developing centrally a low, stout white scabrous point, the margin scabrous-ciliolate with short pustulate hairs: flower-clusters in all the leaf-axils, long-peduncled, somewhat crowded, not obviously racemose: sepals very short, deltoid-ovate to shortly triangular-lanceo- late, obtuse, setulose on the back and strongly hispid-ciliate: corolla short and funnelform: nutlets ovate, straight and erect, lightly rugulose and minutely tuberculate. Habitat of the last, and manifestly allied to it, though its firm texture, peculiar pustulate roughness, as well as the 20 PLANTS BAKERIAN.E. differences in inflorescence, calyx and achene, preclude the confusing of them. It is Mr. Bakers' n. 193. 1 OREOCARYA HORRIDULA. Low inulticipitous perennial, the not stout rather loosely leafy and floriferous steins 4 to 7 inches high, the whole plant strongly setose-hispid : obo vate obtuse upper end of the leaf tapering spatulately to a rather long and narrow petiolar base: racemose short branches of the loose and short inflorescence linear-bracted, but the bracts barely equalling the calyx; this in fruit J inch long, its linear and narrow segments covered with hispid hairs; corolla white, rather more than J inch long, with narrow tube and small spreading limb: nutlets (only one, usually) narrowly ovate, erect and straight, sharply 1 The characters of two northwestern Mertensias may here be given : M. SYMPHYTOIDES. Stout, erect, barely a foot high, leafy to the summit and even throughout the broad cymose-panicled inflorescence with large elliptic-lanceolate acute leaves, these of a bright green and appearing glabrous, but sparsely somewhat tuberculate-scabrous, espec- ially on the margin and the lower face : leafy cyme rather lax ; calyx rather small, deeply cleft, the segments ovate- trigonous, acute, glabrous except as to the margin, this very shortly and almost obscurely scabrous- serrulate : corolla y 2 inch long, quite tubular,, the upper portion quite cylindric and little shorter than the proper tube : nutlets rather coarsely low-tuberculate. Known to me only from Emigrant Springs, in the lava beds of Modoc Co., California, where it was collected by Mrs. R. M. Austin, 20 June, 1894. M. STENOivOBA. Size of the preceding, quite as leafy, but the leaves oblong-lanceolate, acute, thin and quite glaucous, sparsely scabrous, most so marginally : inflorescence as in most species : calyx parted into narrowly lanceolate- acuminate long segments, their margins sparsely setose ciliolate : full grown nutlets scarcely half as long as the calyx and sinuate-rugose. Based Mr. Flodman's n. 752 from the Bridger Mountains, Montana (as to the specimens in my set), and named by Mr. Rydberg "M. lanceolata, DC." But it can have no intimate connection with Pursh's type on which the species was founded ; for that has a " short calyx," while here that organ is rather extremely elongated. ASPERIFOLl^E. 21 margined, the oack showing a few irregular rugse and some interspersed tuberculation. Deer Run, 11 June, on a dry bank; n. 133. OREOCARYA NITIDA. Multicipitous, slightly woody at base, the stoutish stems a foot high, copiously leafy at base? the leaves 2 to 4 inches long, oblanceolate, acute, tapering to a long petiolar basal portion, this again dilated at the insertion, both faces equally silvery-silky or satiny, without other pubescence: flowers copious, in a loose open thyrsus of close racemes: calyx in fruit J inch long, the segments narrowly linear except at the broad base, clothed through- out with a dense white villous tomentum and some inter- spersed setose-hispid hairs; corolla J inch long or more, with very narrow tube abruptly widening to form a short throat, the proper limb three lines broad, the color of the whole apparently white: nutlets (mostly solitary) large, ovate, straight and erect, dark-brownish, closely covered with a minute whitish almost muricate tuberculation. In dry stony ground at Deer Run, 11 June, n. 95. A species noteworthy by the whiteness and softness of its almost satiny indument. Other Asperifolise of the collection are Cryptanthe Fendleri, Greene, n. 780; C. crassisepala, Greene, n. 75; Allocarya scopulorum, Greene, nn. 152, 938; Lappula occidentalis, Greene, n. 327; L. ursina, Greene, n. 471, the species a rare one, but the specimens too young; Lithospermum Torreyi, Nutt., or possibly a new species closely allied to it, n. 127; Oreocarya multicaulis, Greene, n. 455; Eritrichium aretioides, Rydb., n. 845; Mertensia ciliata, Don, nn. 189, 403, 486; M. pratensis, Heller, nn. 391, 773; M. Bakeri, Greene, nn. 293, 497. 22 PLANTS BAKERIAN^. LABIATE. Family not strongly represented in the region, only the following having been collected: Salvia lanceolata, Willd., n. 679; Scutellaria galericulata, Linn., nn. 465, 552, 815; Mentha Canadensis, Linn., n. 547; Dracocephalum parviflorum, Nutt., n. 599; Agastache urticsefolia, Rydb., n. 414; Stachys scopulorum, Greene, n. 359. MONARDELLA PARVIFOLIA. Suffrutescent at base, the many slender tufted stems a foot long more or less, decumbent at base, or more depressed, subcinereous-puberulent: leaves mostly ovate-lanceolate, some oblong-lanceolate, all entire, obtusish, nerveless except as to the quite distinct mid vein, obscurely puberulent, closely glandular-punctate, small, half as long as the internodes, the largest seldom J inch long including the short petiole: heads about } inch broad; bracts scarcely colored, somewhat strigosely pubescent along the veins and densely white-ciliate all around the margin : nerves of the calyx strigose-hairy, the short teeth densely but shortly setose-hirsute : corollas lilac-purple. Frequent in the canon of the Gunnison near Cimarron, where it was first collected by myself in 1896, and now again by Mr. Baker, n. 678. The species may probably in- clude the so-called M. odoratissima of southern Utah. SCROPHULARIACE^;. CASTILLEIA COGNATA! Near C. linaridefolia, as tall and as nearly glabrous, but in habit strict, the leaves both shorter and suberect rather than spreading ; flowers only half as long as in that species, and crowded, forming a spike both narrow and dense : floral bracts less deeply trifid and their segments very unequal, the middle one much the longest, oblong, obtuse, the others both short and narrow, the whole SCROPHULARIACE^}. 23 bract villous: calyx deeply cleft anteriorly; galea of the corolla shorter than the tube. Border of a meadow, at Jack's Cabin, 7 July, n. 616. The collector notes that he saw but one plant, but does not men- tion the occurrence of other species of the genus in that vicinity. That the bracts and calyx are cream-colored, instead of crimson, is one of several hints given in the aspect of the plant, of a possibly hybrid parentage between C. linaridefolia and C. septentrionalis. PENTSTEMON TEUCRIOIDES. Suffrutescent, low, the slender tufted stems erect, 2 to 5 inches high, leafy throughout and floriferous from below the middle, the whole herbage ciner- eous-pubescent: leaves spatulate-linear, entire, almost pun- gently acute, less than J inch long, usually exceeding the interned es : flowers 5 or more in each subcapitate and short- pedicelled glomerule, all forming as it were a secund raceme along the upper one-half and more of the stem : segments of the calyx subulate-lanceolate, acute, entire, wholly herba- ceous: narrow and strongly bilabiate deep-purple corolla about | inch long, glabrous ; sterile filament bearded almost from the base with orange-yellow hairs ; anthers glabrous. Collected at Sapinero, 19 June; said to be common there, on dry ground, n. 186. The specimens are not well in flower ; and the aspect of the plant, particularly as to its inflorescence, is singularly like that of a Teucrium. PENTSTEMON PROCUMBENS. Suffrutescent, low and rather slender, the older and more woody parts of the branches prostrate and rooting, the leafy and floriferous parts assur- gent, the whole 6 to 10 inches long; branchlets retrorsely puberulent, as also the pedicels and calvx. uut leaves green 24 PLANTS BAKERIAN.&. and almost glabrous, these many, only J inch long bat rather exceeding the internodes, spatulate-obovate, obtuse or some of the earliest obcordate-notched, entire, those below the inflorescence with some fascicled smaller ones in their axils, the upper with 1 to 3 flowers in their axils: calyx parted deeply into linear-liguliform abruptly acutish and minutely ciliolate lobes: corolla elongated and narrow; anthers glabrous. Forming large mats on open slopes at Keblar Pass, 7 Aug., n. 733. The species is related to P. csespitosus. It may possibly be identical with Gray's so-called var. suffru- ticosus of that species; but of that I have seen no specimens, and the description is insufficient for the identification of a species. COMPOSITE. SENECIO CONTRISTATUS. Stems several, stout, erect, 2 feet high or less, leafy up to the simple raceme of several large nodding rayless heads: lowest leaves with an elliptic blade 3 inches long and a broadly winged petiole half as long, the cauline more lanceolate, subsessile or sessile, all closely callous-denticulate, scaberulous between the callosities, other- wise glabrous, like all other parts of the plant: heads broadly campanulate, } inch high, the lanceolate acute bracts of the involucre of a very dark red-brown, the inner ones with obvious yellow scarious margin: rays none, disk light-yellow. In small clumps on open ground at Keblar Pass, 14 Aug., n. 787. An interesting addition to that small group of Rocky Mountain species marked with few and large rayless heads. This one is, however, more nearly allied to the southern S. Rusbyi than to its near neighbor, 8. scopulinus. SENECIO PYRRHOCHROUS. Erect, stoutish, 2 feet high, COMPOSITE. 25 glabrous, rather copiously leafy toward the base, remotely bracted above the middle : lower leaves oval, obtuse, coarsely but rather lightly crenate, 2 or 3 inches long, on slender petioles of 4 or 5 inches, the middle cauline lyrate-pinnatifid and the bracts above them similar but reduced and sessile: terminal cymose corymb like that of S. aureus, but the heads larger, the campanulate involucres 4 or 5 lines high: flowers of both disk and ray fiery-red. Common in meadows at Jack's Cabin, 25 July, n. 612. A very handsome subspecies of S. aureus, with large leaves very regularly crenate all around the margin; the flowers of the richest fire-red. Mr. Baker's n. 348 from meadows near Sargent, not yet in full flower at date of July 5, must also be referred here, though in some of these specimens the lowest leaves are subcordate, and many of them almost entire. SENECIO LAPATHIFOLIUS. Stems clustered, stout, more or less decumbent, a foot high or more, leafy throughout, the herbage deep-green and glabrous: leaves 4 to 6 inches long, lanceolate, acute, sessile by a broad, or sometimes taper- ing half-clasping base, undulate, more or less obviously denticulate: heads 5 to 10, large, the campanulate invo- lucres more than J inch high, mostly arising singly from the axils of the leaves, these on very long peduncles, the whole forming a loose subcorymbose panicle; bracts of invo- lucre lanceolate (rather broadly and triangularly so): rays narrow, about as long as the bracts: achenes striate, glabrous. On the divide between Ouray and Telluride, 10 Aug., n. 738. In some ways suggestive of S. crassulus, and doubtless allied to it, but in character very different. The long pedun- cles are peculiarly turbinate-thickened under the involucre, and the whole plant appears to be much more succulent than S. crassulus. 777-5 26 PLANTS BAKERIAN^E. SENECIO PENTODONTUS. Dwarf, multicipitous, the scapi- form peduncles 3 to 5 inches high, the tufted and upright leaves scarcely half as high, these subcoriaceous, their obo vate-spatulate obtuse mostly 5-toothed (often 3-toothed, or even quite entire) blades commonly about as long as the petioles; growing parts of the plant hoary- tomentulose, the older foliage glabrate : peduncles with one or more narrow bracts and bearing mostly 3 slender-pedicel led heads; in- volucres subcylindric, nearly J inch high, their bracts thin, narrowly lanceolate: rays few, yellow, oblong, shorter than the involucral bracts. On open knolls below the limit of trees, near Carson, 2 July, n. 309. An interesting subalpine Senecio which may be regarded as in a manner intermediate between two such different species as S. petrocallis and .8. wernerisefolius. The other Senecios of the sets are the following : 8. admir- abilis, Greene, 732, 875, both fine specimens; '8. amplectens, Gray, 719, 771, also beautifully illustrating this species; S. atratus, Greene,? 756, the foliage too thin and too faintly dentate, perhaps almost as near S. milleflorus ; S. blitoides, Greene, 341,755 ; S.carthamoides, Greene, 731, 851, both num- bers excellent ; 8. chloranthus, Greene, 523, not exactly typi- cal ; S. crassulUSj Gray, 774 ; S. eremophilus, Rich, 596, 748 ; S. Fendleri, Gray, 516, an unusual state with no pinnatifid leaves, 857, quite nearly typical; S.flavulus, Greene, 114, 176; 8.

S. petrocallis, Greene, 770; S. pudicus, Greene, 683, 858; S. spartiodes, Torr. & Gray, 446. ARNICA LANULOSA. Gregarious by horizontal root-stocks, the many stems rather low, 5 to 10 inches high, stoutish, COMPOSITE. 27 very leafy, all the leaves, even the upper cauline, greatly exceeding their internodes, all lanceolate, entire, the longest 3 or 4 inches long including the short petiole, villous-lanate on both faces but most so beneath and there notably par- allel-veined, also minutely viscid-glandular beneath the in- dument, the stem more woolly: heads 3 to 5, short-peduncled, bracts of campanulate involucre biserial, lanceolate, obtusish, appressed -silky but sparsely so: rays small, deep-yellow: disk-corallas with very long densely villous and sessile- glandular tube and very short narrow limb: achenes hir- tellous and also minutely glandular ; pappus long, very fine, merely scabrous, dull-white. On shelving banks of Crested Butte, n. 336, and at Mar- shall Pass, n. 881. Related to A. incana and A, Bernardino,, especially the last, but stout and low, the leaves quite entire, the disk-corollas and the pappus both characteristic. f ARNICA SILVATICA. Stoutish, a foot high or more, with 4 or 5 pairs of leaves mostly large and surpassing the inter- nodes, the stem loosely pubescent, the leaves very sparsely clothed with short appressed hairs and clammy with co- pious minute sessile glands: radical leaves none, lowest pair round-obovate and small, the pair next succeeding very large, obovate, the upper pairs lance-ovate, all more or less connate-sheathing and coarsely dentate: peduncles 3 to 5, terminal and axillary: involucres campanulate, nearly f inch high, the narrow bracts thin, somewhat villous and decidedly viscid: rays large, deep-yellow ; disk-corollas with short soft-villous tube and longer funnelform limb: achenes sparsely villous-hirsute, in no degree glandular; pappus light-tawny. In woods of spruce at Ruby, 8 July, n. 715. A plant' with much the general aspect of A. latifotia, though lower 28 PLANTS BAKERIAN^E. and stouter, but quite distinct by characters of pubescence, flower and fruit. ARNICA PARVIFOLIA. Stems usually 3 or 4 from the end of the rhizome, mostly 8 or 10 inches high and monoce- phalous, each with about 3 pairs of small leaves, the petioles of these and also the stem and peduncles loosely villous and somewhat viscid : lowest leaves subcordate-ovate, remotely and often repandly dentate, the cauline with rhombic-lance- olate acute blade 1 to 1J inches long, the lower ones peti- olate, the upper sessile : involucre narrow-cam panulate, more than J inch high, its lanceolate bracts viscid-pubescent: rays large, golden-yellow, deeply tridendate: slender achenes with short scattered bristly hairs and many minute dots; pappus clear white. Marshall Pass, at 10,000 ft., 19 July, n. 515. Related to A. cordifolia, much like it as to flower and fruit, but of dif- ferent habit and foliage. HELIANTHUS FASCICULARIS. Perennial, rather slender, tbe solitary stem 2 or 3 feet high from a fascicle of small fusiform tuberous roots, glabrous or sparsely pubescent, glau- cescent : leaves opposite, narrowly and acuminately lance- olate, remotely and lightly serrate, triple-nerved below the middle, scabrous on both faces with short pustulate acute hairs, 3 to 6 inches long, on petioles of an inch or less : heads 1 to 3, the broadly campanulate involucre of lance- olate and subulate mostly appressed bracts strigose-pubes- cent and ciliate: achenes oblong, glabrous, about 2J lines long, the ovate-acuminate lacerate-toothed palea3 more than half as long. So far as known first collected by myself at Cimarron, ^Torado, 3 Aug., 1896 ; but it is now in Mr. Baker's collection COMPOSITE. 29 from Gunnison, n. 816. The propagation is by a few run- ners from the crown of the fascicled roots. TETRANEURIS INTERMEDIA. Perennial, csespitose, the slender peduncles 6 to 8 inches high, rarely bractless, usually with one or more leafy bracts below the middle, not rarely parted below the middle into two branches each monocephalous: leaves comparatively short, narrowly spat- ulate-linear and linear, green and glabrate or with a few scattered very long pilose hairs on the lower face or near the margin, rather notably punctate: peduncles more or less villous, canescently so under the involucre, this small, its oblong acutish bracts villous-lanate: palese of the pappus ovate oblong, conspicuously awned. Dry hills at Cimarron, southern Colorado, 6 June, 1901, C. F. Baker, n. 34. Intermediate between the acaulescent and caulescent species of the genus. PSILOSTROPHE BAKERi. Herbaceous, apparently perennial, much branched, 4 to 8 inches high, the branches at earliest flowering not much exceeding the large spatulate-obovate or -oblong green but thinly villous-lanate large basal leaves, these obtuse, entire, some of the cauline coarsely toothed or 3-lobed at or near the apex, all obviously 1 to 3-nerved : branches short, almost divaricate, the breadth of the plant greater than its height : heads scattered, very large, appar- ently always 5-rayed and the rays more than J inch long, deeply 3-lobed : bracts of -involucre green-herbaceous, obvi- ously distinct, their tips spreading: achenes glabrous, closely and strongly striate; palese of the pappus oval, obtuse, more or less toothed across the summit, little longer than broad, not half as long as the achene, nor a third as long as the corolla. 30 PLANTS BAKERIAN.E. Near Montrose, southwestern Colorado, 4 June, and near Grand Junction, 11 June, 1901, C. F. Baker, nn. 14 and 106. Species strongly marked both in habit and characters of fruit. HYMENOPAPPUS OCHROLEUCUS. Perennial, the stoutish caudex branching, each branch with a tuft of petiolate leaves and a subscapiform though branched and corymbose stem 12 to 18 inches high; herbage white-floccose when very young, the stem and fully developed foliage more or less completely glabrate: principal leaves 4 or 5 inches long, pinnate or more or less completely bipinnate, i. e., some of the segments entire, only those below the middle of the rachis parted into one or more segments, all linear : loosely subcorymbose heads 12 to 20, broadly turbinate, J inch high : corollas whitish or cream-color : palese of the pappus rather many and narrow, little exceeding the silky-villous indument of the achene, and of hardly half the length of the corolla-tube. Dry hillsides about Cimarron, Colorado, June, 1901, C. F. Baker, nn. 25 and 269. HYMENOPAPPUS PARVULUS. Tufted stems many on a branching perennial caudex, leafy at base only, rather slen- der, 5 to 9 inches high, bearing a few subcorymbose small heads at summit: leaves canescently tomentose, once or twice pinnately parted into linear segments : turbinate heads only 3 or 3 J lines high ; bracts of, involucre oblong-obovate, mainly green and tomeritulose but with light-green subsca- rious margin : corollas greenish-yellow : achenes with short- villous and spreading pubescence; palese of pappus 7 to 9, cuneate-obcordate, longer than the corolla-tube, the mid vein prominent below, the organ otherwise thin-hyaline. COMPOSITE. 31 On dry stony ground in the lowlands about Gunnison, nn. 449 and 840. ARTEMISIA BAKERI. Allied to A. Mexicana but more slender, and with the tufted stems decumbent or depressed and also rather loosely branching: foliage rather sparse, green and glabrous above, white-torn entose beneath, the lower leaves with few and rather remote pinnate segments, those of the branchlets entire, all linear or with linear seg- ments, the margins narrowly re volute: heads in an ample and loose panicle, many of them short-pedicellate, campanu- late, the outer bracts short, herbaceous, acute, the inner obtuse and largely scarious, all somewhat arachnoid- canescent. This species, very well marked as to habit, was first col- lected by myself, in the canon of the Gunnison, near Cimarron, Colorado, in August of 1896. Mr. Baker now distributes it, and from the original station, or near it, under n. 698. ERIGERON SIMULANS. Near E. pumilus and of the same size and habit, the many short stems crowning the taproot almost or altogether herbaceous; the spatulate-linear leaves strongly and very stiffly hispid-ciliate from the base to the middle, the upper portion (or proper blade) with a finer strigose hairiness closely appressed: pedunculiform mono- cephalous branches sparingly leafy below, slender and naked under the involucre, this green and as if glabrous to the unaided eye, but its outermost bracts sparsely bristly- hairy: rays pale flesh-color or white: outer pappus very conspicuous, of oblong-obovate acutish laciniate-toothed paleae. Stony hills about Cimarron, southern Colorado, 6 June, 32 PLANTS BAKERIAN^E. 1901, C. F. Baker, n. 40. The plant so closely simulates, habitally, the common but always more northerly E.pumilus, that but for its very remarkable double pappus it would have been let pass for that species. But upon examination its pubescence is of another character, and the whole plant is greener and more slender. PLANTAGINACE^;. PLANTAGO RETRORSA. Perennial, of the size and with the habit of P. eriopoda, and with even a closely similar pubes- cence^ but wholly wanting the fuscous woolliness, which so conspicuously marks that species, the leaves not entire but coarsely though sparsely runcinate-toothed below the mid- dle : sepals much more herbaceous, and capsules more elon- gated; seeds elliptic-oblong. Abundant in alkaline meadows at Doyle's, 28 June, n. 627. Excellently marked by the four characters indicated, as distinct from the kindred species, with which it may have been confounded, if before collected ; but the plant is wholly new to me. 1 NYCTAGINACE.E.

Also allied to P. eriopoda, and with definite traces of its basal woolliness, but leaf -outline and leaf -texture very different, all being comparatively thin, not at all ceriaceous, and the outline distinctly obovate, the whole margin apt to be more or less repand-toothed : spikes relatively short, and much more dense than in P. eriopoda; capsules almost globose and not exceeding but even quite included within the calyx, the sepals of which are largely herbaceous, and their narrow scarious margins distinctly ciliolate all around : seeds oval. Species known to me only as collected by myself on the plains of Shasta River in Northern California, twenty-five years since. They were distributed for P. eriopoda, but are now seen to represent something very distinct. NYCTAGINACE.E. 33 and the herbaceous ones, glabrous and very glaucous: leaves much smaller than in A.frograns, subcordate-orbicular to oval, very obtuse, usually about an inch long, on petioles somewhat longer or shorter: flower smaller than in A. fra- grans, the perianth-limb apparently funnelfrom rather than rotate: fruits scabrous on the sides, roughish-tomentulose at summit. This species, easily distinguished from the northern and and true A. fragrans (a large perennial, wholty herbaceous) by its small size, suffrutescent habit, white stems and total lack of clamminess, is well represented in the following numbers: 13, obtained at Montrose, best showing the half- shrubby growth ; 89, from Deer Run, somewhat larger, and 92, from Grand Junction; this last, at least in my set, is a young plant, flowering perhaps the first year from the seed, and thus exhibiting, naturally, no sign of the ultimate woodiness of the stem. ALLIONTA ROTUNDIFOLIA. About a foot high, the stoutish clustered stems ascending, densely crinite-hirsute as to the lower and shorter internodes, the upper portions, as well as the lower face of the uppermost leaves more loosely and hispidly hirsute: lowest leaves suborbicular, obtuse, about 1 J inches long, the upper larger, sometimes round-ovate, all more or less woolly-ciliolate: flowers and fruits not seen. Obtained at Swallow's, between Pueblo and Canon City, 1 June, n. 3. The specimens, though not yet in flower, exhibit in their peculiar foliage and pubescence characters sufficient for the establishment of a species. The inflores- cences are clustered, and arise from the axils of only the uppermost leaves. PAPILIONACE.E. THERMOPSIS PINETORUM. Less than a foct high at flower- ing, in age rather taller; oblong and obovate-oblong leaflets 7776 34 PLANTS BAKERIAN.E. 1J to 2 inches long, obtusish, sparsely appressed-hairy be- neath, glabrous above; stipules ovate, 1 to 1J inches long: racemes short and few-flowered, even subcapitate, the corollas large; calyx villous, its triangular teeth half as long as the tube: pods about 3 inches long, ascending, straight, appressed-pubescent. At Marshall Pass, common in open places among the pine woods, 19 July, n. 485; flowering specimens only; but the fruiting specimens, from precisely the same locality, were obtained by myself, 4 Sept., 1896, and have been kept ever since, under the above name as a new species, awaiting flowering specimens. THERMOPSIS STRICTA. Much taller, even 1J feet high in flower, very strict, and 'with a long interrupted raceme of smallish flowers of which the lowest are subverticillate: mature leaflets If to 2J inches long, mostly oblong or ellip- tical, some of the largest inclining to oblanceolate, glabrous above, sparsely pubescent beneath; ovate stipules 1 to 2 inches long: calyx canescently villous, its teeth narrower, more than half the length of the tube: pods very erect, 2 inches long or more, villous- torn en tose. In meadows at Sapinero, 19 June, n. 173, in flower; also at Gunnison, 25 July, n. 604, in fruit. 1 1 T. ANGUSTATA. Two feet high and somewhat bushy by several well developed leafy sterile branches, but only the main stem bearing flowers : leaflets about 2 inches long, elliptical, deep-green, villous-pubescent beneath (as also the stem), but glabrous above; stipules small and narrow, barely i inch long, or even less, and lanceolate : calyx and pods hoary-tomentose, the latter about 2 inches long, strictly erect. Known only as collected by myself, at Star Valley, in the foothills of the Ruby Mountains, Nevada, 20 July, 1896. The specimens are in fruit only, but by the remarkably narrow, and almost exactly elliptical foliage, and the tomentose pods, a marked species is indicated. COMPOSITE. 35 LTJPINUS RUBRICAULIS. Perennial, the tufted stems slen- der, a foot high or more, simple, remotely leafy with rather small very slender-petioled leaves, both stem, petioles and, in part the leaves dark red-purple and sparingly and min- utely silky-villous : leaflets about 7 or 8, cuneate-oblong or elliptical, unequal, the largest 1J inches long, the slender petioles much longer; stipules small, subulate: raceme ses- sile, 3 or 4 inches long, rather dense, the flowers scattered, middle-sized, pedicels and very gibbous calyx white-silky; corolla dark blue-purple, banner shortest of all the petals, the narrowly pointed falcate keel longest and naked: fruit not seen. On moist slopes of Crested Butte, 6 July, n. 342; con- spicuous by the dark purplish hue of the herbage, and in habit quite an elegant species. LUPINUS ARCEUTHINUS. Stems rather rigidly erect, form- ing large tufts 3 feet high, simple and very leafy, hoary- pubescent throughout, the stem with a villous, the leaves with a more short and appressed silky-velvety indument : leaflets 7 or 8, lance-elliptical, acute, the largest 2 inches long; raceme sessile, 6 inches long, rather dense, all the flowers scattered, rather large; stout pedicels, and short gib- bous calyx scarcely more velvety than the rachis; corolla wholly dark blue-purple, the petals subequal, the not strongly falcate keel densely woolly-ciliate throughout : pods more than an inch long, quite broad, velvety-tomen- tose. At Cedar Edge, 24 June, n. 246. LUPINUS DICHROUS. Size and habit of the last, with similar though somewhat larger foliage, the pubescence both shorter and more scanty, perhaps best described as silvery- 36 PLANTS BAR ERIAN^. canescent; raceme short-ped uncled, less elongated, open and subverticillate; pedicels and short gibbous calyx velvety: corolla at first white, the banner only at length changing to reddish-purple, this rather shorter than the other petals; keel rather broadly lunate and not long-pointed, strongly woolly-ciliate throughout: pods oblong-linear, 1J inches long, silky-tomentose, 5-seeded ; seeds flat, white. Also at Cedar Edge, 24 June, n. 249; the strictly two- colored rather large corollas rendering the plant very attractive. LUPINUS AMPLUS. Stems clustered, stout, 3 feet high, very leafy with leaves of the largest dimensions, the thin elliptic-lanceolate acute leaflets about 10 and 3 to 5 inches long, green and glabrous above, sparsely appressed-silky- hairy beneath and more strongly so on the margin; the stem and peduncles villous: raceme sessile, 10 inches long, both broad and rather dense, nowhere subverticillate: pedicels J inch long or more, densely hirsute, as also the short calyx: corolla of the largest, j inch long; banner shortest, dark-purple; wings violet, .conspicuously striate- veined with purple; keel falcate, slender-pointed, hirtellous- ciliate above the middle: pods not seen, but ovaries silky- tomentose. At Cerro Summit above Cimarron, 17 June, n. 164. Very large and showy, recalling L. magnus of the Californian sea- board, almost as large, but not succulent; and quite as distinct from the far-northwestern L. polyphyllus. LUPINUS LEPTOSTACHYUS. Clustered stems stout, very erect, 2 feet high or more, with relatively small leaves and the smallest ot flowers in very long racemes: leaflets about 9, oblong-linear, abruptly acute, unequal, the longest 1J UNIVEKSITY OF CALIFOENIA LIBEAKY, BERKELEY THIS BOOK IS DUE ON THE LAST DATE STAMPED BELOW Books not returned on time are subject to a fine of 50c per volume after the third day overdue, increasing to $1.00 per volume after the sixth day.
