BOTANICAL EXPLORATIONS SOUTHERN TEXAS i DURING THE SEASON OF 1894. By A. A. -OO. ISSUED FEBRUARY 6, 1895 THE NEW ERA PRINTING HOUSE, 1895. tssa INTRODUCTION. THE State of Texas, an empire in itself, comprising one-twelfth of the area of the United States, with great diversity of soil and climate, must necessarily present a corresponding diversity in plant life. When all of its immense area is thoroughly explored, it will undoubtedly yield as many or perhaps more species than are contained within the limits of Gray's Manual. As is stated in the Introduction to the Botany of the Mexican Bound- ary Survey, a line drawn from the Pan Handle southeast to the vicinity of Corpus Christi, divides the State into two unequal portions. The smaller eastern part is well watered as a whole, and gives rise to more luxuriant vegetation than the other, where rain is uncertain and often scanty. The flora of this eastern section, at least in its northern and eastern portions, has many species in common with the adjacent States of Louisiana and Arkansas and the Indian Territory. The larger southern and western division, in many places a veritable desert, contains many peculiar plants, found only within its limits, es- pecially in the central portions, in the limestone foothills, and in the mountains of the extreme western part. Along the southern border, the species are essentially Mexican, intermingling in the mountain region with more northern forms found in the mountains of New Mexico, and with characteristic Texan plants. Undoubtedly the best part of the State botanically, and also the least known, is the extreme southern portion, from Corpus Christi west to Laredo and south to Brownsville. In the Mexican Boundary Survey, the statement is made that "the botany of this region is too well known from various published accounts to require further details in this place." Nevertheless, the fact remains that practically we know nothing of what it contains. The bulk of Neally's new species were collected be- tween Brazos Santiago and Rio Grande City. Between the latter place and Laredo I find no mention of plants ever having been collected. The rough character of the country, its inaccessibility, drynesss, and the great expense to be incurred in properly working it up, are formidable barriers to an individual explorer. Corpus Christi Bay and the lower Nueces may be considered the northern boundary of this interesting tract of country. The vegetation so characteristic of a dry country is very marked, nearly everything being armed with thorns or spines. At Corpus Christi, where in all, eight 845629 weeks were spent, one can form a very good idea of what the country between there and the Rio Grande is like. The lower, or business por- tion of the town, is built where once the waters of the bay rolled. This low portion ends rather abruptly on the south side, where the bluff rises precipitately to a height of thirty or forty feet. It gradually becomes broader, until its northern portion is about two miles wide. The bulk of this width, though, is an arm which juts out, forming the division between Corpus Christi Bay and Nueces Bay. Its extreme northern portion is low and flat, marshy near the water, and at times of unusually high water, overflowed. The plants which occur on these " Flats" are those which are usually found in saline soil, such as Batis maritima, Suaeda suffrutescens, etc. Here the ascent to the plateau is less abrupt, and the plateau itself lower. Much of this low land, at least near the beach, is composed of a shell deposit, instead of sand. One can dig into it for a distance of several feet without meeting with anything else. Corpus Christi Bay is very shallow, the maximum depth being seven- teen feet, but the average is hardly ten. Nueces Bay is still shallower and full of quicksand. I am told that long ago Spanish ships of the largest size were accustomed to cast anchor where now a boat with a draught of three or four feet would run aground. At present the only deep water inlet is Aransas Pass, at the upper end of Mustang Island. It seems, therefore, that a gradual elevation of the land is slowly going on. The plateau is level, cut here and there near the shore by arroyos, or ravines. Near these the ground is full of holes, which gradually become larger, until finally they cave in, forming side branches. The soil is very rich, and is called " black land," or "black waxy land." When wet by rain it becomes exceedingly sticky, great clods of it clinging to one's shoes, so that walking becomes extremely tiresome. It is covered with sod, and under favorable conditions would be a splendid agricultural country ; but lack of rain makes the raising of crops uncertain, and dur- ing the past year many cattle perished from starvation. Until last April, there had not been a good rain for over four years, nothing but light showers at intervals, and these scarcely sufficed to moisten the ground. Early in April there were two or three heavy rain- storms, but storms of this kind occurring at long intervals do very little good and often much damage. During the spring months there is a great deal of cloudy weather, and in the coast region, one would expect to have an abundance of rain. The strong trade winds which blow almost continually at that time pro- bably carry the clouds away before they have had time to deposit their moisture. The features so characteristic of the Atlantic coast region are here entirely wanting. Swamps are conspicuous by their absence, as likewise are trees, which are found only along the upper end of Nueces Bay. Occasionally Prosopis juliflora, the Mesquite, becomes large enough to be called a tree, but even then is low and spreading. Indeed, low and spreading, stunted-looking trees are the rule, as the tall graceful forms of a more northern climate do not find a place here ; but bushes of various kinds are abundant, forming the dense and usually impenetrable chap- parral. This chapparral is a very deluding thing, too. One ventures into it by way of one of its lanes, which here and there sends off side branches, imagining that by one of them he will find an exit, only at last to discover that the way is completely blocked by a solid mass of bushes. Getting lost in a place of this sort would be a very serious matter. Many species of smaller plants are found only under the chapparral. They have either betaken themselves to these places of safety for self- protection, or are the remnant of a flora which once thickly dotted the open places. When grass is scarce the cattle become omniverous, devouring any- thing that they can chew, whether it be good, bad or indifferent ; but into the thorny wilderness they- cannot penetrate. The collector, in order to be successful in obtaining good specimens from these places, should possess a great amount of patience, go prepared to cut down the bushes, and if he is inclined to profanity will probably exhaust his vocabulary before finishing the job. Nine miles southeast of Corpus Christi is the Oso, a salt water lake, three or four miles in diameter, connected with the bay by two inlets about fifteen feet wide, and distant from each other about a mile. On all maps which I have seen, the Oso is marked as an arm of the bay in- stead of being separated from it by a strip of land, which at the " Blind Oso," its narrowest part, is about 150 yards wide at times of unusually high water. Beyond this narrow strip of dry sand, is a mud flat, a half mile wide, before the waters of the Oso are reached. At other places the strip of land separating the two bodies of water is much wider, being almost a mile on the south side of the Blind Oso. Between the Oso and the Lagoon de Madre is a strip of slightly elevated sandy land, about three miles wide, called Flower Bluff, the principal growth of which is the live oak, reduced to a scrubby bush, from three to eight feet high. Several truck farms are located on it, and although there is more moisture here than at Corpus Christi the vegetables produced are often of an inferior quality. In all, eight weeks were spent at Corpus Christi, from March 3d to I i April i yth, and from May 28th to June 9th. The part explored was a narrow strip along the shore, from the mouth of the Nueces River to Flower Bluff, a distance of twenty-five miles. One day was spent in San Patricio county, across the bay from Corpus Christi. Away from the immediate vicinity of the bay the country is too inaccessible on ac- count of the chapparral, and does not contain enough moisture to make good collecting ground, although it might if there were not several head of cattle to every plant which ventures above ground. The bulk of the collecting was done in and about the town. Two trips were made to the mouth of the Nueces along Nueces Bay, two to the Oso, and one to Flower Bluff. When I arrived there early in March, plants were plentiful and bloom- ing profusely after the slight winter rains. During the last week of March a " norther" came down, followed by another in a few days, when, as if by magic, the plants began to droop, the flowers to disappear, and on some of the pasture land scarcely a sprig of green could be seen nothing but the brown, bare earth. The most prominent herbaceous plants on the plateau in early spring were Lesquerella Gordoni and a species of CEnothera as lately received, apparently close to (E. primiveris. Of shrubs, the most common were Prosopis juliflora, Castela Nicholsoni, Celtis pallida, Zizyphus obtusi- folia, Acacia amentacea, A. tortuosa and Culubrina Texensis. On April iyth I moved to Kerrville, 71 miles northwest of San An- tonio, and about 280 from Corpus Christi. It is a small town of perhaps 1000 inhabitants, situated on the headwaters of the Guadalupe, at an elevation of 1650 feet above sea level, and is one of the health resorts of Texas. It is situated in a limestone formation and surrounded by hills, the highest of which are about 2000 feet above sea level. Occasionally one of these hills is isolated and cone-shaped, like the buttes of the Bad Lands in the Dakotas. They are likewise terraced, a wall of rock two or three feet high completely encircling the hill ; above this a bench of earth, then another rock wall, and so on to the summit, the intervals be- tween the benches becoming less as one ascends. At the northwestern end of the town, the Guadalupe receives a small tributary called Town Creek. My explorations here were confined to the immediate vicinity of Kerrville, along the banks of the Guadalupe for a distance of about two miles, along the banks of Town Creek for about a mile, and the surrounding hills, principally those on the left bank of the river, and at a distance of about a mile from the town. One day was spent along Bear Creek, in the extreme northeastern part of the county, one trip made to a point on Wolf Creek, about fourteen miles north of Kerrville, and one trip up Town Creek for a distance of about seven miles. For at least twenty-five miles on all sides, and for many more in some directions, the same limestone formation prevails, and plant life appears to be pretty uniform throughout. Having found by experience that long trips yielded practically the same things which I could find within a radius of a mile from Kerrville, I directed my attention to thoroughly exploring a small area, dividing the time so that each particular place was visited once a week. The steep, stony, left bank of the river for a distance of about one- fourth of a mile took up at least two days of the week, Town Creek one or two, and the hills the balance of time. To the best of my knowledge, horehound, which is abundant about the streets, and a species of Juniper occasionally met with along Town Creek, are the only plants found in flower or fruit between the middle of April and the first of July that I did not collect. The characteristic plants of the limestone region in Kerr county are many. In fact the bulk of the species are plentiful over the whole area at certain elevations. At no place is there a greater range of more than 400 feet between the lowest and the highest elevations, yet a number of species growin'g abundantly on all the hilltops are not found at the lowest elevations, and some of them only on the summits. Acacia Roemeriana, Coreopsis Drummondii Thelesperma filifoliiim, B if or a Americana, and Brazoria scutellarioides are examples of the hilltop flora. A few of those found at both the highest and lowest elevations are Lesquerella recurvafa, Kuhnistera pulcherrima. Cassia Roemeriana and Erigonum longifolium. Along streams, the dwarf walnut, Juglans rupestris, is very plentiful. Three trips were made to San Antonio, with very satisfactory results, the rich, moist ground along the river banks always producing an abundance of plants. In all, 573 numbers were collected, only a few of them being dupli- cated. Of these, 39 were collected at San Antonio, 4 at Kenedy, Carnes county, 8 at Waco, McLennan county, 248 about Corpus Christi, and 299 about Kerrville. The orders represented by the largest number of species are Com- positae and grasses, of which some 60 species each were collected. Texas is very prolific in grasses, but they grow in scattered clumps or as solitary plants, rarely forming a sward, as they do further north. The Leguminosae are represented by over 50 species, many of which are i 8 very plentiful. Next come Euphorbiaceae with about 25 species, La- biatae with 20, and Umbelliferae and Cruciferae with 12 or 15. As before mentioned, Corpus Christi Bay and the lower Nueces may be considered the northern boundary of a flora peculiar to southern Texas. Within the limits of this, six of my eleven new species were col- lected, and a number of rare ones re-discovered. Between this and the more elevated limestone district, is a tract 200 miles wide at some places, which appears to have a flora more or less distinct from the other two sections, although many species common to both are found within its limits. My knowledge of this central tract was obtained principally from observations made along the railroad while traveling. Here the Mesquite is much more abundant than in the south- ern section, while in the limestone region proper it seems to be entirely wanting. At San Antonio, or rather a few miles west, the limestone formation and hilly ground begins, with a distinct and sharply marked flora, the Mesquite and other plants so common and rather monotonous suddenly giving place to groups of Sapindus, Monarda citriodora, etc. My thanks are due to Mr. Frederick V. Coville, Government Botanist, who kindly gave me the opportunity of making my determinations at the U. S. National Herbarium, and determined the fund; to Mr. J. N. Rose, who determined the Umbelliferae ; to Prof. F. Lamson Scribner, for the determination of the grasses ; to Dr. N. L. Britton, for the use of the botanical library of Columbia College and of the herbarium while making corrections and final determinations ; to Mr. John K. Small, for the determination of the Polygonums and Rumex ; to Dr. Thos. C. Por- ter, for the determination of 100 of the first numbers, and to Mr. M. S. Bebb, for the determination of the willows. Without the aid of these gentlemen, it would have been impossible to produce the present work. In the matter of citations of publication, it is to be regretted that in perhaps a dozen cases the date could not be obtained. Certain numbers of the Botanical Magazine and Botanical Register could not be con- sulted, as well as several other works. Apology must be made for the unnecessary omission of many type localities. The first part of the enumeration was prepared before I had access to the original descriptions, and later this omission was over- looked. The last line in the paragraphs under the enumeration and descrip- tions of species refers to the date of collection and the number of the plant, the latter in parenthesis, as " May 26 (1781)."

Club, 22 : 44 .(1895). * [PLATE I.] Perennial, slender, glabrous, light green, somewhat glaucescent. Root- stock woody, creeping, 1-2 dm. long; roots fibrous; stem erect, 8-9 dm. long, simple or sparingly branched above, leafy through- out, slightly flexuous, strongly channeled, . woody below ; leaves lanceolate or oblong-lanceolate, 6-13 cm. long, 1.5-4.5 cm. broad, acute or sometimes attenuate at the apex, the lower ones obtuse or truncate at the base, the upper acute or acuminate at the base, all rather long petioled, coriaceous, light-green, undulate and crisped, neither prominently nor conspicuously nerved ; petioles strict, 2-5 cm. long ; ocreae cylindric, nearly one-half as long as the inter- nodes; inflorescence terminal, simply paniculate, naked; racemes (fruiting) 5-12 cm. long, dense, rather erect, the terminal one usually about twice as long as the lateral ones ; calyx 2 mm. broad ; pedicels varying from 2-4 mm. in length, jointed below the middle; wings broadly ovate cordate, broader than high, i cm. long, 1-1.2 cm. broad, straw-colored, sometimes slightly constricted below the apex, conspicuously and prominently nerved, crenulate and undu- late, each one bearing an oblong-ovoid callosity, the three wings strongly spirally twisted; achene broadly oblong-ovoid, 3 mm. long, short-pointed, chestnut-colored, its faces nearly flat, its angles con- spicuously margined. Found growing in the mud on the margins of ponds near Kenedy, Games county, Texas, by Mr. A. A. Heller, collected in flower and fruit on May 26, 1894 (1781). The altitude of the station is about 400 feet. Its nearest relative is Rumex altissimus , from which, however, it differs in having more characteristically lanceolate leaves, which are longer- petioled, crisped and the larger ones more or less truncate at the base instead of acuminate. The panicle of R. spiralis is more open, not leafy, and its racemes are denser and thicker. Wings twice to thrice as large as in R. altissimus invest the broadly oblong-ovoid achene. The former are broader than high and strikingly cordate, whereas those of R. altissimus are higher than broad, not strongly cordate and less prom- inently nerved. So far as observed three callosities are developed throughout. POLYGONUM L. Sp. PI. 359 (1753). Polygonum densiflorum Meisn. in Mart. Fl.

Occurring sparingly along the Guadalupe and Town Creek, at Kerr- ville. This plant agrees very well with Buckley's description, the "caule scandente, foliis pedunculatis, integris, lato-ovatis, acuminatis mucronatis," being quite correct, but the thin leaves are coriaceous, which character is much more apparent in dried specimens than in fresh ones. They are light green, glaucous beneath. " Part of these stem leaflets are on long tendril-like petioles," corresponds also. The slender, conical calyx is slightly contracted near the middle, an inch or more long, bright scarlet in color, rarely reflexed at the tips and then only slightly. The figure in Bot. Mag. /. 6594, of C. coccinea Engelm. does not agree with this plant, neither do specimens in the Columbia College herbarium, cultivated at Easton, Pa. C. coccinea has much shorter and broader flowers, thick, coriaceous, and rounder and more recticulated leaflets. Distributed as C. " Texana" Buckley. A form intermediate between this plant and C. Simsii was collected on the Guadalupe, in close proximity to both. The leaflets are more coriaceous than those of either of the others, glaucous, though less so than in C. Texensis. The flower is dull purple red, or rather brick red, and in shape more like that of C. Simsii. April 19 to June 26 (1608); type locality, "on the Colorado river, above Austin." RANUNCULUS L.

This plant has quite an interesting history. It is very plentiful about Kerrville, ranging from the banks of the Guadalupe to almost to the summits of the hills. I at once recognized it as something strange, and concluded that it was either new or K. decumbens, and as it did not prove to be that species, named it K. pulcherrima n. sp., and as such distributed it. The cause of this error is that Dr. Gray very much underrated the excellent work of Scheele, refusing, at least for a time, to 51 recognize some very good species which he described. In this case he consigned Scheele's plant to synonomy, making it equal to Petalostemon violaceus var. pubescens A. Gray, a variety which was never published, and according to Gray's own statement, has no characters to separate it from the species, except more pubescence on the calyx. In one of the works, I think either PL Wright, or PL FendL, I came across a reference to Scheele's species, which led me to think that my plant might be the same. Upon referring to the original description in Linnaea, it became evident that Petalostemon virgatum, which name, however, was used previously by Nees, is an excellent species, and agrees in all essential points with my specimens. New Braunfels, his type locality, is some sixty or seventy miles southeast of Kerrville, but the character of the country is the same. The plant can be distinguished from K. purpurea (violaceus} at a glance. June 14 (1857). INDIGOFERA L. Sp. PL 751 (1753). Indigofera leptosepala Nutt. ; T. & G. Fl. N. A. i : 298 (1838).

At Corpus Christi, in open ground near the beach, altitude about 10 feet. May 30 (1795), type locality; "prope Zelaya Mexicanorum." Sida Helleri Rose, n. sp. A low shrubby plant 3 cm. or less high, forming clumps 6 cm. in diame- ter ; branches woody and procumbent, often .covered with sand, and with erect, herbaceous, flowering shoots ; leaves small, a little broader than long, 8 to 1 2 mm. long, rounded at apex, truncate or rounded at base, 3 to 5 -nerved, coarsely crenate, more or less abundantly stellate-pubescent ; petioles 6 to 1 2 mm. long ; stipules persistent, foliaceous, linear, obtuse, 4 mm. long ; flowers small, subsessile, solitary in the axis of the leaves; calyx campanulate, 5- lobed ; sepals ovate, obtuse, 3 mm. long, in fruit 6 mm. long ; corolla pale copper-colored, larger than the calyx ; petals broad, somewhat oblique, glabrous ; stamens united into a slender tube ; styles 5, slender, with capitate stigmas; capsule deeply 5-lobed; carpels obtuse at tip, somewhat inflated, dehiscing at apex, one- seeded. Very common ; flowers open about 4 p. M. Collected along the sandy shore of Corpus Christi Bay at the Oso, by A. A. Heller, April 9, 1894 (1533). Very much like S. cuneifolia Gray (PI. Wright. 7 : 18), but with very different shaped leaves, much longer fruiting, calyx with obtuse in- stead of acute lobes, larger, more inflated and different shaped capsules. The following note is from a letter of Mr. E. G. Baker, the well- known authority on Malvaceae : 11 1 have taken an opportunity of comparing your Sida, and I have very little to add from what you have already told me. It is a very interesting little plant, closely allied to S. cuneifolia A. Gray, but per- fectly distinct. The shape, size and base of the leaves are different, and the calyx seems a good deal larger in your plant than in S. cuneifolia. It has the same ovate, membranous, slightly inflated carpels, so different from the Eu Sideae, and I suppose you will place it in the Section Pseudo- Malvastrum. I see there is generally one rather large leafy bract at the point of junction of the pedicel with the main stem." J. N. ROSE. Sida physocalyx A. Gray, Bost. Jour. Nat. Hist. 6: 163 (1850). In rich, open ground at Kerrville, altitude 1650 feet, about 75 miles south of the type locality. Stems numerous, and about 2 feet long in older plants, from a stout root. Flowers small, dull yellow, usually opening about eleven o'clock a. m., and remaining open an hour or less. 67 On a bright, warm day, the time of opening may be an hour or more earlier.

I do not know that this species has been collected since it was first described in 1850, until obtained by Mr. Heller. The type was collected by Lindheimer in 1845, but ^ had been previously obtained by Berlandier as early as 1834. The species had not been previously represented in the National Herbarium, and is probably the same with many of the herbariums. The type, which I have seen, is deposited in the Gray Herbarium along with 2 sheets from the Berlandier Herbarium. Dr. J. Gregg's No. 523 collected in 1848-9 seems to be a different species. Mr. Heller's plants were collected near Corpus Christi in April, 1894, and are in fine condition. J. N. ROSE. 68 Viola vertidllata Ort. Dec. PL 4: 50 (1797). lonidium poly galaefo Hum Vent. Jard.

Perennial, the main root sending out fibrous rootlets ; stem erect, slightly woody at base, two to three feet high, cymosely branched above, glaucous, purplish below, green above and marked with one or two pubescent lines, otherwise glabrous ; leaves opposite, oval or ovate, acute or the lowest obtusish, and broader, somewhat oblique at base ; petioles about one-fifth the length of the blade ; peduncles comparatively stout, shorter than the leaves; umbels 15-20 flow- ered, on pedicels nearly half the length of the peduncles ; flowers white with prominently exserted horns. 78 A beautiful species related to the northern A. qitadrifoaa. At first it was thought that it might be the West Indian A. nivea L., but reference to the plate on which that species was founded, to specimens in the Her- barium of Columbia College, and to descriptions, show that it is not that plant. A. perennis is perhaps its nearest neighbor in some re- spects, but has smaller flowers, and leaves tapering at both ends; be- sides, its range is eastern, and it grows in low ground. In the Herbarium of Columbia College is a plant from either western Texas or New Mexico, referable to this species, although the flowers are smaller. Dr. Gray named it A. perennis. In the U. S. National Her- barium is a specimen of A. Texana collected by Lindheimer near New Braunfels, but unnamed if I remember rightly.

At Corpus Christi, growing in dry open ground, sea level to 20 feet, was a plant referred to this species. The flowers are usually twice as large, as in ordinary V. officinalis ', the plant stouter and more simple, with a somewhat different leaf. March 9 (1419); type locality, "in Europae mediterraneae rude- ratis." Verbena quadrangulata n. sp. (PLATE 6.) Herbaceous, prostrate and spreading from an apparently perennial, slen- der root ; whole plant pilose, especially the stems ; the upper surface of the leaves smoother, with the pubescence appressed ; cymosely branching, leafy throughout; leaves an inch or less in length, opposite, rather distant, broadly ovate, abruptly contracted into a margined petiole, three parted, the middle lobe largest, three to five cleft, the lateral ones two to three cleft ; spikes dense, bracts narrowly lanceolate, slender, pointed, slightly more than half the length of the calyx; calyx prominently five-ridged, the ridges green, ending in short, slender tips, which are joined by a scarious connective ; flowers very small, white, or pinkish tinged, tube ex- serted, the spreading lobes notched ; fruit shorter than the calyx, four-lobed, the lobes oblong, blunt, from a broad base, angled and pitted, surmounted by a four-winged crown, the wings of which are alternate with the lobes. 85 This most peculiar plant has the habit and general appearance of the species of Verbenas which bear rather large and showy flowers, as V. bipinnatifida and V. Aubletia, but its very small flower at once throws it out of that group. Its most striking feature is the shape of the fruit, which is well shown in the accompanying plate. The crown of this curiously-shaped seed is much like the four-angled fruit of certain species of Gaura and is hollow. Until the exact limit of Verbena seeds be known, it is provisionally placed under this genus, although it is pro- bably an undescribed genus. Collected at Corpus Christi, where it is plentiful in open ground, at both the southern and northern ends of the town. Altitude 10-35 feet. March 5 (1388). LIPPIAL.Sp. PI. 633(1753).

It is abundant as far east as San Antonio, and noticed at intervals be- tween there and Kenedy. May 1 8 (1761). Monarda pectinata Nutt. Jour. Acad. Phila. (II.) i : 182 (1849). What appears to be this long-lost and rare species is very plentiful about Corpus Chribti, especially southeast of the town. My specimens were collected in the Arroyo. Great quantities of it were noticed along the railroad between Corpus Christi and Kenedy. Neither the herba- rium of Columbia College nor the U. S. National herbarium at Wash- ington, contain specimens of M. pectinata, but at the Academy of Natural Sciences, Philadelphia, is a small specimen from New Mexico, collected by Fendler, No. 602, which is referable to it. My specimens are rather tall, usually 2 feet and over in height, espe- cially if growing in rich, shaded ground, with a hard, woody rootstock, which gives it the appearance of being a perennial. The flowers are lemon-yellow, resinous dotted, ciliate pubescent. Tne ciliate bracts are whitened, yellowish, or faintly reddish tinged. The following is Nut- tail's original description : "Biennial? slightly pubescent, leaves oblong, lanceolate, denticulate, shortly petiolate; capituli proliferous, rather small, subtended by her- baceous bracts, some of them purplish, ovate, acute, strongly ciliate, as well as the elongated setaceous teeth of the calyx ; corolla widely rin- gent, the tube scarcely exserted beyond the calyx."

Ipomoea Neatly i Coulter, Cont. U. S. Nat. Herb. No. 2, 46 (1890). First noticed in cultivation at Corpus Christi, and afterwards found twining over bushes along the upper end of the bay. The handsome purple flowers do not in the least resemble those of an Ipomoea, but plainly belong to a Scrophulariaceous plant. The capsule, though, bears a superficial resemblance to that of an Ipomoea. May 29 (1790): type locality, Mexico. PENTSTEMON Soland. in Ait. Hort. Kew. 3: 511 (1789). Pentstemon Cobaea Nutt. Trans. Am. Phil. Soc. (II.) 5 : 182 (1834).? 92 The plant doubtfully referred to this species is plentiful about Kerrville, at an altitude of 1600-1800 feet. It varies in height from one to two feet, has large and rather broad flowers, ranging in color from white tinged with blue to almost rose color. Its leaves are inclined to be nar- rower, and the flower usually not more than half the size of the P. Co- baea found farther north. There are a number of specimens from Texas in the Herbarium of Columbia College identical with my plants. April 19 (1610); -type locality, Arkansas, on the -Red river. Pentstemon Guadalupensis n. sp. (PLATE 7.) Low, 8-15 inches high, branching from the perennial rootstock, which sends down numerous, thick, fibrous roots ; glabrous below, the in- florescence glandular pubescent and viscid ; root leaves linear or spatulate linear, sessile, clustered, 2-4 inches long, acute or acutish; stem leaves from linear to lanceolate, sessile, becoming broader and shorter as they ascend, the upper with broad, almost cordate base, 1-3 inches long, acute, smooth on both sides, entire, or some of the upper ones sparingly denticulate, prominently one-nerved ; calyx-teeth about the length of the corolla tube, lanceolate or ovate- lanceolate, glandular puberulent, especially on the margins ; corolla white or sometimes faintly tinged with purple, short, less than an inch in length, broad in proportion, the spreading lobes almost equal ; sterile filament broadened above, the upper half bearded on one side with yellow hairs. This species belongs in the Genuini division, near P. tubiflorus and P. albidus. It was distributed under the latter name, as there are speci- mens in the National Herbarium identical with my plants, which are called P. albidus. It is very plentiful in dry, stony ground along the Guadalupe and Town Creek, altitude 1600-1650 feet, and often growing in company with P. Cobaea? Sometimes large patches of ground are white \\ith it. Usually several plants grow together in a clump. April 19 (1609). Pentstemon triflorus n. sp. 4 (PLATE 8.) Herbaceous, erect, usually 2-3 feet high, simple, very glabrous up to the inflorescence; root leaves spatulate, on margined petioles about equal in length to the blade, entire or minutely denticulate, obtuse or acutish ; stem leaves entire or dentate, the dentations sometimes 93 present only on the lower part, sometimes near the upper end, and occasionally most marked in the middle; the first two or three pairs oblong, on rather short, margined petioles, the others sessile, becoming shorter and broader as they ascend the stem, the upper pair especially, which are usually ovate lanceolate and clasping ; in- florescence glandular puberulent and viscid ; peduncles slender, less than an inch in length, usually three flowered ; pedicels shorter than the calyx as a rule ; calyx equalling or slightly exceeding the slen- der tube, the slender, oblong or lanceolate lobes glandular ciliate ; flowers bright rose-purple, paler inside and marked with dark stripes, an inch or more in length, gradually dilated, the lobes spreading ; sterile filament smooth, slightly dilated at the tip. Some leaf forms of this striking plant are much like those of the plant referred to P. Cobaea, but are thinner, dark green and shining; be- ides, the flowers are more slender and longer. The color of the flowers is much like that of the beautiful P. Smallii of the Carolina mountains. It was found only along the summit of one hill northeast of Kerrville, altitude 2000 feet, an elevation not reaches by the two other species. April 26 (1654). CONOBEA Aubl. PI.
