CONTRIBUTIONS TO A FLORA OF THE BAHAMIAN ARCHIPELAGO. CHARLES F. MILLSPAUGH, M.D. During field and herbarium studies of the flora of the Greater An¬ tillean Islands, conducted by Dr. N. L. Britton, Director of the New York Botanical Garden, and the Author, each came to the conclusion that a thorough investigation of the Bahamian Archipelago would throw much desired light upon many problems of plant distribution and mutation, and offer a probable solution of the question of the age of these interest¬ ing islands. A joint investigation of such collections as had been previously made on the archipelago proved them to be in many cases meagre in material, scrap¬ py in character, or from islands too widely separated to afford even a par¬ tial solution of the problems presented. They therefore decided to so¬ licit the consent of those botanists representing the Government of Great Britain, to which these islands belong, and the support of the institutions they, themselves represent, in view of organizing a thorough exploration of the islands included in the archipelago. This being in both instances unhesitatingly given, three expeditions were equipped for immediate field work and others planned, to cover within the next two years, all the is¬ lands included. Up to the present writing, the survey thus organized has covered the following groups:—Great Bahama, the Abacos, the Isaacs, the Berry Is¬ lands, the Bimini Islands, the New Providence area, the Exuma Chain, the Inaguas and Grand Turk. In these, a large amount of information and material has been accumulated by Dr. and Mrs. Britton, Mr. Nash, Mr. Brace, and the Author. In accomplishing this, not only have the usual lines of communication been utilized, but special vessels have been equipped and commissioned. I 37 / 138 Field Columbian Museum — Botany, Vol. II. The following material (over 7,000 sheets), resulting from this survey, or secured by exchange, gift, loan, or purchase, is deposited in duplicate in both institutions, where it is being studied by the co-workers, who are also taking occasion at various intervals to consult the collections of Cates- by, Eggers, Hjalmarsson, Brace, Daniell, Herrick, Allen, Barbour & Bryant, and others, deposited in European and American herbaria. In addition, a complete series of the orchids, cacti, tillandsias, and other difficult groups is being collected alive and studied in the conservatories of the Garden. COLLECTORS. Brace — Mr. Louis J. K. Brace began his collections in the Bahamas in 1875. He worked principally on New Providence until 1880, but also secured material on Fortune Island or Long Cay, and Andros. His work resulted in about 525 numbers, which were sent to Kew Gar¬ dens. A duplicate set is still in his possession. He began field work under the present survey in September, 1904 (see Britton & Brace), and later in the same year was commissioned by the Garden to make an exploration of the Abaco Islands, where he collected as follows: Green Turtle Cay (1475-1515), Allen’s Cay (1526-54), Spanish Cay (1555-62), Man-o’-War Cay (1563-89), Pigeon Cay (1662-73), Elbow Cay (1688-1712), and on the island of Abaco at Butler Bay (1516-25), Marsh Harbor (1590-1661, 1713-53, 1787-1846), Great Cistern (1674-87, 1754-86), Cherokee Sound (1847-9, 1898-1980, 1999, 2080-84, 2086), Eight Mile Bay (1850-97), opposite Cherokee Settlement (1981-98, 2064-79), Old Kerr’s Point (2000-2036), and California road (2037-63), a total of 611 numbers. Following this expedition he continued work on New Providence in localities from which, from time to time, it became necessary to have more material of previously secured species. In June, 1905, a commission was given him by both the Garden and this Museum to continue, on Great Bahama, the work already undertaken there. (See Britton & Millspaugh.) On this exploration he collected at Eight Mile Rocks (3633-5, 3671-3738), Deadman’s Reef (3631-2), and the western extremity of the island (3484-3630, 3636-57). He also collected Garden Cay (3658-70), and visited (during his sailings to and from Great Bahama) North Bimini (3461-75, 3479-83), South Bimini (3476-8), North Cat Cay (3739- 54), and Andros Island (3755-6), and after returning to New Provi¬ dence collected Nos. 3893-3918. Britton — Dr. N. L. Britton collected on New Providence in April, 1904, in the neighborhood of Nassau, South Side Beach, Blue Hills, Far- Feb., 1906. Pr^enunc. Baham. — Millsbaugh. *39 ringdon Road, West Bay Street Road, Cunningham Road, Lake Cunningham, and Old Fort. In this preliminary investigation, in company with the Author (see Millsp.), he collected 158 numbers, (1-158). An account of the field work is published in the Journal of the New York Botanical Garden 5: 129-136. See also Britton & Brace, and Britton & Millspaugh. B. 6° Br. — Britton & Brace — Dr. N. L. Britton, Mrs. E. G. Brit¬ ton, and Mr. Louis J. K. Brace collected together on New Providence (Nos. 159-328, 361-872), and Hog Island (329-360), in September and October, 1904. They ranged New Providence with great thor¬ oughness, penetrating to the coast region north, east, south, and west, and to the coppices, pine barrens, and openings in the neighborhood of Nassau, Fort Montague, Farringdon Road, Swingate, Maidenhead, Tea House, Race Course, Delaport, Fox Hills, Village Road, Mt. Vernon, Rifle Range, Harold Road, Carmichael, Adelaide, Southwest Landing, Miller’s, Blue Hills, Soldiers Road, Lake Cunningham, Winton, Old Fort, Waterloo, Clifton, Mt. Pleasant, Fort Charlotte, Gambier, Killarney, Bonefish Pond, and Seven Hills. The com¬ moner things were not taken, the attempt being made to secure only such species as were previously unfamiliar or those which had only been gathered when out of character. This survey resulted in 714 particularly interesting plants embracing the series of numbers in¬ dicated above. An account of this expedition is published in the Journal of the New York Botanical Garden 5: 201-209. B. 6° M. —Britton & Millspaugh — Drs. N. L. Britton and C. F. Mills- paugh, accompanied by Mr. M. A. Howe, began an exploration of the Berry Islands, Great Bahama, and the Exuma Chain, in January, 1905. A schooner was chartered and equipped at Nassau, where, after a day’s delay on account of heavy weather (during which col¬ lecting was done in the scrublands and coppices south of Nassau (2085-2110), the expedition began at Rose Island (2111-2166), and Hog Island (2167-2176). The first island of the Berry Group vis¬ ited was Whale Cay (2177-2201), followed by Frozen Cay (2202- 2224), Little Harbor Cay (2225-2254), Great Sturrup Cay (2255- 2285), Goat Cay (2286-2301), Lignum Vitae Cay (2302-2332), and Great Harbor Cay (2333-2354). The exploration began on Great Bahamalsland at Eight Mile Rocks (2355-2596), and was continued at Barnett’s Point (2597-2716), and Golden Grove (2717-2741). Re¬ turning to Nassau, a fresh start was made to the Exuma Chain, of which the following islands were diligently searched: Ship Channel 140 Field Columbian Museum — Botany, Vol. II. Cay (2742-2767), Cay north of Wide Opening (2768-2804), Cave Cay (2805-2836), Little Galiot (2837-2850), Great Galiot (2851- 2860), Great Guana (2861-2922), Great Exuma (2923-3051, 3073- 3141), and Stocking Island (3052-3072). On Great Exuma the regions worked were the scrub lands and coppices lying west of Georgetown; Hayne’s Road from the east to the west shores across the island; and the Rolletown scrub lands and coppices. The total series of this exploration is 1057 sheets. An account of this expedition may be found in the Journal of the New York Botanical Garden 6: 77-85. Coke?- — Dr. William C. Coker, botanist of the Bahamian expedition of the Geographical Society of Baltimore, assisted by Messrs. C. A. Shore and F. M. Hanes, collected in the summer of 1903 on the fol¬ lowing islands: New Providence (1-193, 247-305, 551), Andros Is¬ land and Little and Great Mangrove Cays (194-234), Green Cay (235-246), George’s Island (306-317), Eleuthera (318-421), Cat Is¬ land (422-437), Rum Cay (438-457), Watlings Island (458-491, 521, 528), Long Island (492-520, 524), Water Cay (523, 525), Abaco (558-568, 575-6), and Elbow Cay (569-574). This collection was deposited in the herbarium of the New York Botanical Garden, and forms the basis of his “Vegetation of the Bahama Islands,” in Shat- tuck’s “The Bahama Islands.” Owing to the insufficiency of the material secured many phanerogams therein published are based upon provisional determination only. The cryptogams exist under a separate series of numbers. Coope ?-— Dr. William Cooper paid a visit to New Providence in 1859 for the purpose of making dredgings for zoological material. While there he collected in the neighborhood of Nassau about 100 plants for his friend, Dr. John Torrey. The prime set of these plants is now in the herbarium of the New York Botanical Garden. See Bull. Tor¬ rey Club 1 7 :190. Curtiss —Mr. A. H. Curtiss collected his first series of “West Indian Plants” in April, 1903, in the neighborhood of Nassau, New Provi¬ dence. This series comprises numbers 1-211, of which the prime set, with the unnumbered unicates, is deposited in the herbarium of the New York Botanical Garden, and the first distributed set in the herbarium of this Museum. Earle — Prof. F. S. Earle collected during one day only, on New Provi¬ dence (Nos. 1-79), while on his way to Cuba, in March, 1903. His plants, largely from the vicinity of Nassau, are in the herbarium of the Garden. Feb., 1906. Pr^enunc. Baham.— Millspaugh. 141 E. G. B. — Mrs. N. L. Britton, often accompanied by Mr. Brace, visited, in April and May, 1905, all those stations on New Providence pre¬ viously collected by Britton & Brace, at which it had become desir¬ able to secure additional material of interesting plants or characters missing on previous notable species. In addition to achieving marked success in this undertaking, she secured many other plants of particular interest. Her survey resulted in 310 sheets (Nos. 3141-3460), and is mentioned in the Journal of the -New York Bo¬ tanical Garden 5:129-136. See also Britton & Brace. Hitchcock — Dr. J. T. Rothrock and Prof. Albert S. Hitchcock collected in the Bahamas in November and December, 1890. The collections were largely made by Prof. Hitchcock on New Providence, Eleuthera, Cat, Watlings, Crooked, Fortune, and Inagua, and form the basis of his “Plants collected in the Bahamas,” etc. The material collect¬ ed was deposited in the herbarium of the Missouri Botanical Gar¬ den, from which, through the kindness of the director, Dr. William Trelease, the author has been allowed to reassemble the sheets. The collection, embracing about 600 sheets, is at this writing a loan to the Field Columbian Museum. Howe —Dr. Marshall A. Howe, algologist of the New York Botanical Garden, has collected extensively the sea vegetation of the Bahamas, accompanying Dr. Britton and the author on their first trip, and later, Britton & Millspaugh. He also accompanied the author up¬ on the Bimini explorations. See Journal New York Botanical Gar¬ den 5:129-1-36 and 6:77-85. Millsp. — C. F. Millspaugh—the author began his collections among the islands on New Providence, in April, 1904, in company with Dr. Britton (see Britton), visiting substantially the same stations, where, as his collecting was to extend to other islands, each kept his indi¬ vidual series of numerals. He collected at the following localities: Blue Hills (2048-2100), South Shore (2101-2151 and 2262-2277), West Bay Street road (2152-2178), pine barrens and hammock lands along Lake Cunningham road (2179-2217), region of Lake Cun¬ ningham (2218-2244), Farringdon Road (2245-7), Swingate (2248- 51), Old Fort (2252-4), and Waterloo (2255-61). Then hiring and commissioning a sloop, he sailed in company with Dr. M.A. Howe(see Howe) for an investigation of the Bimini Islands, collecting at the following stations: West End Bight, New Providence (2278-2293), Joulter’s Cays (2294-2304), Gun Cay (2305-2328), North Cat Cay (2329-2347, 2415), South Bimini (2348-2368, 2379-85, 2387-98, 142 Field Columbian Museum — Botany, Vol. II. 2406-2414), North Bimini (2369-78, 2386, 2399-2405), South Cat Cay, (2416-2441).* Again in January, 1905, he collected in the fol¬ lowing localities while awaiting the arrival of Dr. Britton (see Brit¬ ton & Millspaugh): Blue Hills road (2442-4, 2461-81), Silver Cay (2445-2460), and South Side, Soldiers Road, Fort Montague and Fort Fincastle (2482-2502). Following immediately upon this, see Britton & Millspaugh. \ N. 6° T. — Nash & Taylor—Messrs. Geo. V. Nash and Norman Taylor, of the New York Botanical Garden, were commissioned by the Gar¬ den, in October, 1904, to investigate the Inaguas. They made an exhaustive survey of the islands, collecting on Inagua 482 numbers (874-1138 and 1258-1474), on Sheep Cay 23 numbers (1139-1161), and on Little Inagua 96 numbers (1162-1257). In September, 1905, on their return from an exploration in Haiti, they spent a week on Grand Turk Island, collecting all such plants as were noted by them at that season, 136 numbers (3757-3892.) Accounts of these expe¬ ditions may be found in the Journal of the New York Botanical Gar¬ den 6:1-19 and 189-191. Northrop —Mrs. Alice (Rich) Northrop, accompanied by her husband, Prof. John I. Northrop, made, in 1890, a large collection of the plants of New Providence (Nos. 1-239, 280-331), Rose Island (251), Salt Cay (240-244, 271-279), Hog Island (245-8, 252-70), and An¬ dros (332-758). These plants formed the basis of Mrs. Northrop’s “Flora of New Providence and Andros.” They are now deposited in equal sets in the herbaria of this Museum and the Garden. / Wight — Mr. Alex. E. Wight, under the patronage of the Gray Herbari¬ um, of Cambridge, Mass., made a Bahamian collection of 275 num¬ bers from March to May, 1905. He collected on New Providence and Hog Island (Nos. 1 226 and 271-275), and on Andros (227- 270). The resulting plants are being determined at the Gray Her¬ barium, where the initial set will be retained and the duplicate sets distributed to this Museum, the New York Botanical Garden, and others. Prof. B. L. Robinson has kindly communicated, in advance, to the author all those numbers falling within the natural orders treated in this Praenuncia. *An account of this expedition may be found in the Journal of the New York Botanical Garden 5:129-136.

E. buxifolia flexuosa (Kth.) Boiss. Anyone seeing this species in the field would at once recognize it as clearly distinct from E. buxifolia. Its purplish coloration, cinereous glaucescence, rounded flat leaves and spreading habit cause it to resemble E. Cayensis far more closely than E. buxifolia. Leaves glauco-cinereous, ovate, rounded at the apex and unequal base .3-1 cm. x .2—.6 cm. Involucres turbinate, short pediceled, smooth without, densely bearded within, margin entire; gldnds 4, large, cordate, nearly equalling the appendages; stamens 5, the filaments bearded and tufted below ; seeds triangular, pink-ashen, farinose, the angles rounded and prominent, the facets slightly anastomose-rugose trans¬ versely. Maritime sands and sand-pocketed rocks. Not seen north of the Exuma Chain. Ship Channel Cay — B. & M. 2747.

Foliis breviter petiolatis, deltoideo-ovatis vel triangulari-ovatis abrupte attenuatis ad margine revoluto-intumescentis, pagina utruque furfureo-farinosis, sti- pulis late ovatis blepharociliatis, involucris solitariis turbinatis brevi pedicellatis, extus glabris intus ad faucam barbatis, lobis triangularibus acutis ciliatis, glandulis nigris complano-orbiculatis, facie notis vario- larum insignis, appendices minutis carnosis vel obsoletis, stigmata ad mediam bifurcatis, filamentae barbatis. Capsulae glabris. Semen fuscis triangulo-ovatis fascies minute papillatis. t Plants rigidly erect or diffusely prostrate 20 — 30 cm. Leaves 2.5 to 5 mm. long, 1 to 2.5 mm. wide. Seeds .8 x .5 mm. The specimens * representing the extremes of this species are so widely different in gen¬ eral appearance as to almost convince one that they represent two strongly .marked species. This difference, however, lies entirely in the habit of the plants and the size of the leaves. The tallest erect form with small, ovate leaves (3796) passes through the type (3888) to a more diffuse, larger leaved form (1305) and a fully prostrate plant with much larger, sickle-shaped leaves (1 cm. x 3 mm.) with a somewhat less intumescent margin.

Mr. Hitchcock’s plant, while having (on account of its greatly re¬ duced leaves) a quite distinct general appearance of difference from C. fulva (as well represented by C. Wright’s 1357 Monte Verde, Cuba, May 30, 1859,) nevertheless has no other characters of differentiation. It is fairly well connected in leaf size and form with the Wright plant through Mr. Wright’s other 1357 collected at the base of Farallones r Sept. 29, i860, which is in the same fruiting stage as the Hitchcock plant. Of this Farallones plant Mr. Wright says, “ A slender bush 6 to 10 feet high: in thick woods.” Sauvalle (FI. Cub. 113) considers this species synonymous with the Jamaican C. ferruginea Swartz, this however is not the case, the differ¬ ences are broad and evident. Feb., 1906. Pr^enunc.

Mr. Wright’s Majanabajo, Cuba 3173 with the remark “forma foliis lanceolatis.” The sheet of this number in Herb. Gray, Cambridge (one of Mr. Wright’s original series), proves to be an entirely different species. This may be designated as follows: Callicarpa lancifolia sp. nov. Ramulis cum cymis petiolis foliorumque tomento stellari ferrugineo canescentibus, foliis crassis lanceolatis apice acutis ad basin attenuatis brevipetiolatis, supra nigra, ad sicca valde reticulato-rugosis et minute resinosis, infra lutea dense stellato-canescentibus, margine leviter et irre- gulariter crenato-denticulosis.

Eastern Cuba, C. Wright No. 3173 in Herb. Gray, Cambridge, U. S. A. type. Leaves 5 cm. long, 1 cm. broad, strongly bicolor; they differ from those of C.' fulva Rich, in their shape, the far less prominence of the veins beneath, and in not having the pubescence thereon so thick and strongly tufted.

There are two plants of Wright, Cuba ori- entali bearing his number 421, one being this species and the other P. ilicifolium, evidently a case of attempted matching of plants before distribution, unfortunately therefore I am compelled to take the later gathered Bahamian plant for the type. The foliage form and shape is very variable, never however even ap¬ proaching that of P. ilicifolium, in which the margins are crenate and spinous throughout, while those of P. Wrightii are simply spinous and that only on the upper half of the leaf. Both sides of the leaf in P. ilicifolium are pubescent, while in P. Wrightii the upper side is shin¬ ing and strongly reticulate, while the lower surface is resinous pulver¬ ulent. Clerodendron aculeatum (L.) Griseb. Rare in collections.

The present paper embodies the results of a study of the material representing the genus Citharexylum in the collections of John Donnell Smith, the Gray Herbarium, and the herbarium of the Field Museum of Natural History. It is intended as preliminary to a synoptical revision of the group, which the writer already has well under way. The generic limitations are those of Bentham & Hooker, f. Genera Plantarum, ii, 1149, and of Briquet in Engler & Prantl, Die natiirlichen Pflanzenfamilien, iv. Ab. 3a, 159; and the Latin form of the generic name is that adopted by Linnaeus in the first edition of the Species Plantarum, notwithstanding the earlier use of the Greek termination. The writer desires to express his thanks to Mr. John Donnell Smith for the loan of his excellent suite of specimens of this genus, and to Prof. B. L. Robinson of the Gray Herbarium, where the greater part of this work was done. Citharexylum Bourgeauianum, sp. nov. Tree: branches somewhat 4-angled, striate, alternately flattened at the nodes; the ultimate branches evenly pubescent with short spreading hairs: leaves opposite, ovate to oblong-lanceolate, including the petiole 6 to 18 cm. long, 1.5 to 6 cm. broad, usually acuminate, acute or obtuse, entire, glabrous above except for a slight puberulence on the sunken midrib, velvety pubescent beneath, narrowed at the base into a canaliculate 1 to 2 cm. long petiole; midrib and lateral nerves rather prominent on the under surface: inflorescence terminat¬ ing the stem and branches in elongated racemes, occasionally some¬ what paniculately disposed, 2 dm. or less in length, hirsutish pubescent; bracts subulate, 1 to 2 mm. long, equaling or slightly exceeding the stoutish pedicels, soon recurved and more or less persistent: calyx somewhat tubular or deeply cup-shaped, about 5 mm. long, crenately 5-lobed, hirtellous on the outer surface and slightly puberulent within: corolla subsalverform, while; tube equaling’ or barely exceed¬ ing the calyx, pubescent in the throat; lobes oblong, 3 mm. long, pubescent 011 both surfaces: fruit not seen. — Mexico.

Issued Dec*31,1907 New or Noteworthy Spermatophytes from Mexico, Central America, and the West Indies. By J. M. GREENMAN. The diagnoses and notes here presented are the results of critical study in the determination of several recent collections of plants from Mexico, Central America and the West Indies, particularly those of Mr. Edward A. Goldman, Professor Cassiano Conzatti, Dr. George F. Gaumer, Professors C. R. Barnes, C. J. Chamberlain and W. J. G. Land, Dr. Charles F. Millspaugh, Dr. J. N. Rose and assist¬ ants, Sr. Dr. Fernando Altamirano, Professor W. A. Kellerman, the late Dr. G. M. Emrick, Mr. H. A. Van Hermann, and several others including the writer. The material of certain groups, especially in the genus Senecio collected by Mr. C. G. Pringle, has been gener¬ ously submitted to me for identification by Professor B. L. Robinson. The new species here proposed in this genus are preliminary to a forthcoming monograph of the North American Senecios. Cyperus ochraceus Vahl, Enum. ii. 325 (1805). Specimens agreeing well with the original description and with West Indian representatives of this species were collected at Laguna, near the City of Vera Cruz, Mexico, 22 January, 1906, J. M. Greenman , no. 30 (hb. Field Mus.). -This species seems not to have been noted by Hemsley in the Biologia Centrali- Americana. Hechtia macrophylla Greenman, sp. nov. Leaves about 1 m. in length, 3.5 cm. broad just above the base, gradually tapering to the apex, glabrous above, lepidote-cinere- ous beneath; margins spinose; spines 3 cm. or less apart, up¬ wardly curved, 6 mm. or less in length, usually bearing a tuft of persistent white floccose tomentum in the axils: inflorescence paniculate, about 4 dm. long, 1.5 to 2 dm. broad, lepidote- tomentulose; ultimate branches 2 to 12 cm. long, spicate, more or less loosely but evenly flowered throughout their entire length; floral bracts ovate, acute, 4 mm. long: staminate flowers sessile, about 5 mm. long in anthesis, spreading or reflexed; sepals 247 248 Field Columbian Museum — Botany, Vol. II. broadly ovate, 2.5 mm. long, acute; petals elliptic or elliptic- obovate, about 4 mm. long, strongly concave, free or slightly united at the base; ovary rudimentary: pistillate flowers and fruit unknown.— Mexico. State of Vera Cruz: Carrizal, 12 to 14 May, 1901, E. A. Goldman , no. 712 (hb. U. S. Nat. Mus.; fragment and photograph in hb. Field Mus.). The species here described is apparently nearest related to Hechtia Schottii Baker, and H. texensis Watson; from the for¬ mer it differs in having longer leaves, more profusely branched inflorescence, and somewhat smaller floral bracts; from the latter it is readily separated by the longer leaves, the presence of conspicuous tufts of tomentum in the upper axils of the leaf-spines, and by the smaller and more scattered flowers. Hechtia Schottii Baker, in Hemsl. Biol. Cent.-Am. Bot. iii. 318 (1884) & Handb. Bromel. 139 (1889); Mez in DC., Monogr. Phan. ix. 548 (1896). In the herbarium of the Field Museum there is a specimen, collected by Schott in Yucatan, which is unmistakably refer¬ able to Hechtia. The label accompanying the plant bears no number, and likewise no time of collection, but it bears the data “Maxeana.” The specimen consists of leaves, an inflores¬ cence of staminate flowers, and a portion of a panicle bearing mature fruit. The characters exhibited by all these parts agree well with Baker’s description, hence the plant is confi¬ dently referred to the above species; and, moreover, it probably represents a part of the same collection on which the species was founded.

These agree in habit and foliar characters with flowering specimens which were secured in the same locality by Dr. A. Schott and also by Dr. Geo. F. Gaumer. The species is widely distributed, occurring from Mexico to South America, and although well known from flowering specimens, the fruit seems not to have been hitherto described, hence the following characterization is here given: Dec. 1907. Spermatophytes from Mexico — Greenman. 249 Mature capsules large, 3.5 to 4 cm. long, subcylindrical or obtusely triangular, short-acuminate at the apex; valves dorsally pale- stramineous, glabrous, 1-nerved, recurved and somewhat spirally twisted; exocarp readily separating from the endocarp; seeds including the coma about 3 cm. long.— Mexico.

Southeastern U. S. 238 ( I 9°3)- Dr. Sereno Watson very clearly defined the above species and pointed out the characters by which it is readily distinguished from T. gracilis HBK. to which it was referred by C. B. Clarke in DC. Monogr. Phaner. iii. 297 (1881). The examination of a considerable number of specimens from Florida and elsewhere shows that Dr. Watson’s species retains the distinctive characters originally ascribed to it without any evidence, at least as far as yet observed by the writer, of intergradation with the South American species. It seems best therefore to regard T. flori¬ dana Watson as well worthy of specific rank. The following specimens are identical in every detail with Dr. Watson’s species.— Mexico. State of Yucatan: Izamal, Dr. Geo. F. Gaumer, no. 573 (hb. Field Mus.); Chichankanab, Dr. Geo. F. Gaumer , no. 1855 (hb. Field Mus.). This species has not been recorded hitherto from Yucatan.

The vernicose character of the young stem and leaves, the short axillary inflorescences, the two-flowered segments of the fertile spike and the distinctly acuminate endocarp well char¬ acterize this species. The nearest affinity of P. vernicosum is with P. Wattii Krug & Urban, from which it differs in having relatively shorter and broader leaves, the fruit not constricted below the limb of the calyx, and a smaller and distinctly acu¬ minate instead of acute endocarp.

Guatteria Gaumeri Greenman, sp. nov. Tree, 10 to 15 m. high: stem and branches covered with a gray bark; ultimate branchlets glabrous or sparingly strigulose-puberulent: leaves alternate, petiolate, lanceolate to elliptic-lanceolate, 5 to 15 cm. long, 2 to 2.5 cm. broad, usually short-acuminate and obtuse, rarely retuse at the apex, entire, glabrous on both surfaces or in the very early stages slightly pubescent with a few scattered appressed hairs, soon glabrate and rather strongly reticulate-nerved; petioles stoutish, 3 to 10 mm. long, canaliculate, often turning blackish in the dried state: inflorescence terminal or lateral; peduncles thickish, 1 to 3 cm. in length, jointed, sparingly pubes¬ cent with appressed tawny hairs, bracteate at the base and usually bearing a single ovate acute or acutish ciliate fer- rugineous-pubescent bract below the middle: sepals subrotund, 3 to 5 mm. high, usually broader than long, ciliate and sparingly pubescent to glabrous: petals large, oblong-ovate to some¬ what obovate, 2 to 4.3 cm. long, 1.2 to 3 cm. broad, thick and leathery: berries numerous, elliptic-obovoid, about 1 cm. long, 7 to 8 mm. in diameter, minutely verrucose, glabrous: stipes slender, 1.5 cm. or less in length; torus somewhat depressed- globose.— Mexico. State of Yucatan: vicinity of Izamal, specimens communicated February, May, June, and July, 1906, Dr. Geo. F. Gaumer (hb. Field Mus., catalogue nos. 189976-189- 978, 189160, 189161). In general appearance the species here proposed resembles G. dolichopoda Donn. Sm., but it differs in the less acuminate and blunt leaves, character of the pubescence, subrotund sepals, larger petals, shorter peduncles and stipes. G. Gaumeri is rich throughout all its parts in oil-glands, and when crushed it produces a pleasant aromatic odor. Dr. Gaumer in whose honor the species is named states that the plant is known about Izamal under the name of “ Elemuy,” and that from it is obtained one of the most valuable medicines used in Yucatan.

This interesting species, known from Cuba, from Guatemala to Brazil, from tropical and south Africa and Madagascar, seems not to have been recorded hitherto from Mexico. Specimens 252 Field Columbian Museum — Botany, Vol. II. collected at Cordoba by Dr. Asa Gray and referred by him to the above species, although no published record of them has been found by the writer, bear somewhat larger fruit than my num¬ ber 124, but differ in no other apparent regard.

Dec. 1907 Spermatophytes from Mexico — Greenman. 253 with which it has been confused, but from which it differs in having a pubescent inflorescence, more oblong and copiously glandular petals, in having also the inner or upper petal less conspicuously clawed and bearing a scale-like fold on the inner or upper side near the base, and finally by the shorter barely exserted stamens. Phaseolus (§Drepanocarpos) polyanthus Greenman, sp. nov. Stem robust, angulate-striate, sparingly pubescent with ascending, spreading or even reflexed hairs: leaves petiolate, trifoliolate; petioles 4 to 10 cm. long, slightly pubescent; stipules triangular-ovate, 5 to 6 mm. long, acute; leaflets rhombic-ovate, or the lateral obliquely ovate, 4 to 10 cm. long, 3 to 9 cm. broad, mucronate-acute, entire, subtruncate to obtuse at the base, dark green and substrigose-hirsute above, slightly paler and hirtellous-puberulent beneath, more or less glabrate, 3-nerved and bearing tufts of white villous hairs in the axils of the veins on the under side; petiolules stoutish, about 5 mm. long, densely tawny-hirsute above; stipels subfalcate-linear, 3 to 4 mm. long, glabrous or essentially so: inflorescence in elongated axillary racemes, 2.5 dm. or less in length; rhachis pubescent; bracts lance-attenuate, about 7 mm. long, pubescent; pedicels becom¬ ing 12 mm. in length, glabrous or nearly so, and as well as the bracts persistent; bracteoles subtending the calyx, linear- lanceolate to lance-oblong, 6 to 7 mm. long, 1 to 1.5 mm. broad, acute, 3-5-nerved, ciliolate: calyx about 5 mm. high, subbila¬ biate, or 2-lobed; tube 3 mm. long; upper lobe emarginate; the lower lobe 3-toothed with the midddle tooth ovate, acute, 2 mm. long, the lateral teeth shorter and obtuse: vexillum somewhat oblong-obovate, 12 mm. long, nearly or quite as broad, short-unguiculate with a broad claw; disk barely exceeding 1 mm. in length, crenate-margined: ovules commonly 6: mature fruit not seen.— Mexico.

The species is rather striking on account of the large membranous leaflets, many-flowered inflorescences, persistent pedicels, and the narrow bracts and bracteoles. It suggests P. multiflorus Willd. and P. pedicellatus Benth, but is quite distinct from either of them. Astrocasia Rob. & Millsp. in Engl. Bot. Jahrb. xxxvi.

Acalypha Seleriana Greenman, sp. nov. Shrub, 1 to 2.5 m. high, branched; stem and branches covered with a reddish-brown or grayish bark and dotted with numerous lenticels; the younger branchlets densely pubescent with short horizontally spreading tawny hairs: leaves petiolate, ovate to oblong-lanceolate, 2.5 to 5 cm. long, 1 to 3 cm. broad, acute or obtuse, dentate or crenate-dentate, obtuse to rounded at the base, 3-nerved, thin and membranous, at first pubescent on both surfaces especially on the veins beneath, later more or less glabrate; petioles 3 to 18 mm. long, densely pubescent; stipules lance-linear, 1.5 to 2 mm. long; caducous: inflorescence chiefly axillary: spikes of fertile flowers inconspicuous, slender, few-flowered: pistillate flowers small, sessile, solitary in the axils of minute 3-parted bracts about 0.5 mm. high: calyx 1 mm. long, 5-parted into narrowly lanceolate acute divisions, sparingly pubescent: ovary muricate-hispid; style 3-parted. or occasionally 2-parted; divisions thickened and roughish at the base, branching into about 9 laciniate-fimbriate divisions: spikes of staminate flowers numerous, uniaxillary, slender, sessile or short-pedunculate, 1 to 8 cm. long, 2 to 3 mm. thick, erect, spreading, or occasionally more or less reflexed: mature capsules and seeds not seen.— A. mollis Millsp. in Field Col.

Acalypha mollis HBK. to which species some of the specimens above cited have been hitherto referred is described as an herba¬ ceous plant with distinctly pedunculate spikes, and with 2-3- flowered reniform-ovate-n-15-dentate bracts. On these charac¬ ters alone A. Seleriana may be readily separated. The species here proposed seems to be quite unique on account of the shrubby habit, the numerous sender sessile or subsessile spikes of stami- nate flowers, and the pistillate flowers solitary in the axils of exceedingly minute 3-parted bracts. Dalechampia Schottii Greenman, sp. nov. Stems twining, covered below with a grayish bark; branches terete, striate, pubescent with spreading or reflexed hairs: leaves petiolate, simple and undivided, subtrinervate from the base, ovate or ovate lanceolate, 2-7.5 cm. long, 1.5-4 cm. broad, rounded to acuminate at the apex, mucronate-acute, subentire or somewhat dentate in the lower half, obtuse to subcordate at the base, usually bearing on the upper side at the junction of petiole and blade two subulate appendages, pubescent on both surfaces, glabrate above; petioles 0.5-2.5 cm. long, pubescent; stipules narrowly lanceolate to almost subulate, 2-6 mm. long: peduncles 1-3 cm. long, striate, pubescent; the petaloid involucral bracts small, ovate, 6-12 mm. long, 3-8 mm. broad, acuminate or merely acute at the apex, obtuse at the base, 3-nerved, spar¬ ingly denticulate, externally pubescent, ciliate: calyx of the staminate flowers 6-parted; divisions lanceolate, 2-2.5 mm. long, acute, entire, glabrous: calyx of pistillate flowers 7-12- parted; divisions linear-lanceolate, about 5 mm. long during anthesis, pectinate and hirsute-pubescent, persistent and becom¬ ing 1 cm. in length at maturity; ovary 3-celled, puberulent; style cylindrical, stoutish; stigma subtrilobed, not dilated: capsule depressed-globose, inconspicuously puberulent, reddish- brown or blackish in the dried state; seeds subglobose, about 3.5 mm. long, rugulose.— Mexico.

State of Yucatan: Chichankanab, Dr. Geo. F. Gaunter, nos. 1512, 1430 in part (hb. Field Mus.). Some of the specimens above cited have been hitherto doubt¬ fully referred to Dalechampia denticulata Wright of the West Indies. From this species, however, D. Schottii differs in having uniformly smaller leaves, shorter petioles, smaller floral bracts and a nondilated stigma. Moreover, in D. denticulata the leaves and floral bracts are distinctly cordate, while in D. Schottii the leaves are from obtuse to subcordate at the base and the floral bracts are narrowed below to an obtuse base. The variety trijoliolata suggests D. triphylla, var. mexicana Mull. Arg., but the latter has petioles very much longer in proportion to the length of the leaf-blade. Jatropha Gaumeri Greenman sp. nov. Tree, 5 to 10 m. high, much-branched: trunk 2 to 5 dm. in diameter; branches and branchlets thick and somewhat fleshy: leaves alternate, petiolate, palmately 7-nerved, broadly ovate, 5 to 18 cm. long, 4.5 to 15 cm. broad, abruptly caudate-acumi¬ nate, acute, entire, or occasionally subdenticulate in the lower portion, rarely sublobate, deeply cordate to subtruncate at the base, membranous, glabrous above, tawny-pubescent along the veins at the base of the blade beneath, otherwise glabrous; petioles 2.5 to 13 cm. long, glabrous except near the blade: inflorescence in terminal or axillary short-pedunculate com¬ pound cymes, 2.5 cm. or less in length, glabrous or with a few tawny hairs in the axils of the deltoid or triangular-ovate acute glabrous bracts; peduncles 1 cm. or less in length: flowers sessile, monoecious, whitish or cream-colored: calyx gamosepalous, 2 to 3 mm. high, glabrous, 5-lobed, persistent; lobes erect in anthesis, subrotund, slightly unequal, entire: corolla 6 to 7 mm. long, tubular for about two-thirds its length, externally gla¬ brous, densely ferruginous-pubescent towards the base within; lobes 5, erect or slightly spreading, oblong-ovate, rounded at the apex: glands usually 5, occasionally 3: stamens 8, included; the outer series or cycle consisting of 5 distinct stamens about equalling the more or less coalescent filaments of the 3 inner stamens; anthers oblong, acutish: capsule oblong-globose, subtriangular in cross-section, 15 to 18 mm. long, nearly or quite as broad, glabrous, septicidally dehiscent; the carpels later splitting along the median line: seeds carunculate, oblong, about 13 mm. long, 11 mm. broad, slightly roughened.— Ficus Jaliscana Millsp.

Spermatophytes from Mexico — Greenman. 257 In leaf-outline and in the pubescence of the leaf the species here proposed suggests J. yucatanensis Briquet in Ann. Conserv. & Jard. Bot. Geneve, iv. 230 (1900), but it differs in having larger leaves which are abruptly caudate-acuminate and termi¬ nated by a very slender acumen, shorter peduncles, essentially glabrous inflorescence, deltoid bracts, sessile flowers, and 8 instead of 10 stamens. The plant grows as a rather profusely branching tree with thick and somewhat fleshy branches and twigs. The almost leafless condition of the tree and its light gray appearance render it a conspicuous feature of the “scrub” and woodlands about the City of Izamal. It passes under the Mayan name of “Pom- olche;” and its stems are said to be used by the native people in making the so-called “Chul” or whistles. Gouania Conzattii Greenman, sp. nov. Stem terete or slightly angulate above, sparingly pubescent; leaves alternate, petiolate, ovate or subrotund-ovate, rounded to short-acuminate and submucronate-acute at the apex, crenate- dentate, shallowly cordate at the base, dark green and hirsute- pubescent above in the younger stages, more or less glabrate, subtomentose beneath; midrib and veins prominent on the under side of the leaf; petioles 1 cm. or less in length: inflorescence terminating the stem and upper branches in spicate racemes together forming a more or less leafy panicle: flowers sessile, or on very short pedicels: calyx-limb 5-lobed; lobes triangular- ovate, acute, entire, externally as well as the entire inflorescence tawny-pubescent; disk distinctly 5-lobed and the lobes about one-half as long as the lobes of the calyx, 2-dentate and more or less persistent: petals strongly cucullate, 1 mm. long: mature capsules triangular, 6 to 7 mm. high, including the strongly developed wings 7 to 9 mm. in diameter, glabrous or nearly so; seeds oval, 3 to 4 mm. long, smooth and shining, convex on the outer surface, 2-faced and more or less 2-scalloped on the inner surface.— Mexico. State of Oaxaca: Cerro San Felipe, altitude 1,700 m., 15 September, 1906, C. Conzatti, no. 1567 (hb. Field Mus.). Habitally and in leaf-outline G. Conzattii resembles G. tomentosa Jacq., but differs in having a sparingly pubescent stem, larger flowers, and also in bearing capsules which are nearly twice as long in the vertical axis, and producing seeds which are fully twice larger than G. tomentosa.

State of Oaxaca: Almoloyas, altitude 800 m., 25 December, 1906, C. Conzatti, no. 1666 (hb. Field Mus.). It is with some hesitation that the writer describes a leafless plant as new to science, but the present one is so distinctive in its ligneous stem, inflorescence and floral characters that it seems best to present the above characterization. The species is named in honor of the distinguished botanist, Professor Cassiano Conzatti, Director of the Normal School in the City of Oaxaca, Mexico. Ipomoea tentaculifera Greenm. Proc. Am.

State of Sinaloa: near Rosario, on the road to Acaponeta, 27 July, 1897, Dr. J. N. Rose, no. 1858 (hb. U. S. Nat. Mus., and hb. Field Mus.); between Rosario and Concepcion, 23 July, 1897, Dr. J. N. Rose, no. 3269 (hb. U. S. Nat. Mus., and hb. 260 Field Columbian Museum — Botany, Vol. II. Field Mus.). The affinity of C. cinaloanum is in all probability with the obscure C. scabrum Moc. & Sesse, and it may eventually prove to be conspecific. The leaf-margins on an individual plant often vary from entire to conspicuously dentate in the apical portion; and the inflorescence, here as in several other species of the genus, may be either simple or compound. Citharexylum Rosei Greenman, sp. nov. Stem and branches covered with a grayish or reddish brown cortex, terete or subtetragonal; ultimate branchlets 4-angled, cinereous-hirsute: leaves opposite, lanceolate or oblanceolate, 1 to 3 cm. long, 1 cm. or less broad, obtuse to rounded at the apex, entire, narrowed below to a subpetiolate base, hirtellous- pubescent on the upper surface, cinereous-tomentulose beneath: inflorescence terminating the branchlets in few-flowered short racemes; pedicels 3 to 4.5 mm. long: flowers not seen: calyx persistent and in the fruiting stage 2 to 2.5 mm. high, shallow, somewhat saucer-shaped, truncate, pubescent: mature fruit oblong, 7 to 8 mm. long in the dried state; pyrenae elliptic, 6 to 7 mm. long, concavo-convex, strongly corrugated on the outer or convex surface.— Mexico. State of Queretaro: between Higuerillas and San Pablo near the latter station, 24 August, 1905, J. N. Rose, Jos. H. Painter & J. S. Rose, no. 9827 (hb. U. S. Nat. Mus., and hb. Field Mus.). This species resembles C. Altamiranum to which it is closely related, but from which it differs amply in having smaller leaves of different outline, a more dense tomentum, and in its shorter, shallower and trun¬ cate calyx, and corrugated pyrenae. Vitex Gaumeri Greenman, sp. nov. Tree, 10 to 15 m. in height: branches covered with a grayish bark; ultimate branchlets tawny-pubescent: leaves opposite, petiolate, palmately compound; petioles 3 to 9.5 cm. long, vel¬ vety pubescent; leaflets 5 to 7, petiolulate, ovate to elliptic- oblong, rarely tending to become obovate, 1.5 to 11 cm. long, 0.5 to 5. cm. broad, usually short-acuminate and acute or occa¬ sionally rounded at the apex, entire, obtuse to subcordate at the base, dark green and pubescent above, glabrate in age, pale and densely tomentulose beneath; midrib and lateral veins prominent on the under surface, but the anastomosing of the ultimate veins not conspicuously reticulated; petiolules 0.5 to 2.7 cm. in length, velvety pubescent: the pedunculate panicu¬ late cymes axillary, clustered at the ends of the branches, 2 dm. or less in length: calyx small, 2.5 mm. long, subbilabiate, rather acutely 5-toothed, externally pubescent: corolla irregular, bilabiate, about 9 mm. long; tube erect, 5 mm. high, narrowly funnel-form; the two posterior corolla-lobes small, subrotund, 2 mm. long and broad, reflexed; the lower lip or three anterior lobes of the corolla spreading, 5 to 6 mm. long, the median lobe slightly pulverulent on the upper surface near its base: stamens 4, didynamous, exserted; filaments narrow, slightly Dec. 1907. Spermatophytes from Mexico — Greenman. 261 pubescent: style about equalling the two longer stamens: fruit depressed-globose, 1.5 cm. in diameter in the dried state.— Vitex pyramidata Millsp. Field Col. Mus. Bot. Ser. i. 317 (1896), not Rob.— Mexico. State of Yucatan: vicinity of Izamal, March-April, 1895, Dr. Geo. F. Gaunter, no. 607, flowering speci¬ men, (hb. Field Mus., and hb. Gray), type; near Izamal, coll, of 1888, Dr. Geo. F. Gaunter, flowering Specimen, without num¬ ber (hb. Field Mus., and hb. Kew); vicinity of Merida, June, 1865, Dr. A. Schott, no. 582, fruiting specimen, (hb. Field Mus.). The species here described is nearly related to V. pyramidata Rob. with which it has been confused, but from which it differs in being a tree instead of a shrub, in having longer petiolules which, as well as the petioles themselves, are velvety pubes¬ cent instead of pulverulent, in having a paler lower leaf-surface, smaller flowers, in the absence of villous hairs at the base of the anterior lip of the corolla on its upper surface, and finally in having a more pubescent and somewhat more sharply dentate calyx. Dr. George F. Gaumer in whose honor the above species is named states that the plant here described is a tree growing in the forests about Izamal, where it attains a height of about 15 meters. The flowers, moreover, are said by Dr. Gaumer to be bright purple. The tree passes under the native Mayan name of “Yaxnic.” Scutellaria aurea Rob. & Greenm. Am. Journ. Sci. 1 . 163 (1895).

State of Oaxaca: Cerro San Antonio, altitude 1,800 m., 28 October, 1906, C. Conzatti, no. 1584 (hb. Field Mus.).

Definite mention of the variety terminalis under the genus Justicia with complete reference to synonomy seems not to have been made hitherto.

Royoc L., but it may be readily separated by the persistent pubescence over the entire plant, the sessile or subsessile inflorescence and fruit slightly shorter corolla, somewhat more complete union of the flowers, and by the slightly longer and more oblique pyrenae. The plant is known in Yucatan under the Mayan name of “Joyoc” (Hoyoc). Crusea violacea A. Brongn., acc. to Neumann, in Rev. Hortic. Ser. II. iv. 368 (1846); v. 61, pi. 30, fig. 4 (1846). The following specimens agree in every essential detail with the descriptions and illustration of the above little-known species, and for the present at least they seem best placed here. — Mexico*.

Professor William Trelease has kindly furnished me with a copy 264 Field Columbian Museum — Botany, Vol. II. of the original descriptions and a photograph of the illustration of the above species from the Revue Horticole. I am indebted, moreover, to Dr. Casimir DeCandolle who has kindly made for me a critical comparison of my no. 209 with Crusea calocephala DC. in the Prodromus herbarium. From Dr. DeCandolle’s letter I quote the following:— “I have com¬ pared the Crusea specimens you sent me with that of C. caloce¬ phala in the Prodromus herbarium. The case of that species is unfortunately not quite clear as you will see by the following: C. calocephala DC. is represented in the herbarium by Mocino’s plate n. 497 (an original plate, by the way, and not a tracing), together with Dunant’s specimen from Peru. Now it happens that these two documents do not seem to belong to the same species, for the plate (of which I sent you yesterday a good tracing, in a separate roller) shows penninerved leaves, whilst in Dunant’s specimen the leaves have the same nervation as in your specimen. Now on the other hand Dunant’s specimen differs from yours— 1st by the shape of its involucral leaves which are more attenuate at the base; 2d by its calyx being densely pubescent from its base upwards, whilst in your specimens it is much less pubescent and mostly on its upper part only. Consequently I consider your specimens as specifically distinct from both Mocino’s plate and Dunant’s specimen. Moreover I must also draw your attention to the fact that in Mocino’s plate, the corolla is coloured in red (which please inscribe on the tracing when it reaches you) whilst your plant seems to have blue flowers. As for C. rubra Cham. & Schlecht. it is also certainly distinct from your plant, as it has much shorter and strigose hairs and longer petioles.” Both C. calocephala DC. and C. rubra Cham. & Schlecht. are somewhat confused, and very little is known about C. violacea Brongn. In fact the entire genus Crusea, as well as Spermacoce, needs a careful revision, which, however, can only be done satisfactorily after a critical comparison of the ample material of our recent collections with types existing only in European herbaria. Lobelia regalis Fernald, Proc. Am. Acad, xxxvi. 503 (1901). Excellent specimens of this species were collected at Ejutla, State of Oaxaca, Mexico, altitude 1,300 m., 12 December, 1906, C. Conzatti, no. 1638 (hb. Field Mus.). This collection records another station for one of the most beautiful species of the genus, and one which is well worthy of introducing into cultivation.

The only other recorded locality for this species is that cited under the original description, namely Tomellin Canon, Oaxaca, where it was secured by Mr. C. G. Pringle in 1894. Dec. 1907. Spermatophytes from Mexico — Greenman. 265 Brickellia Kellermanii Greenman, sp. nov. Stem erect, nearly 1 m. in height, lignescent at the base, terete, tomentulose: lower leaves opposite, the upper alternate, short-petiolate, oblong-lanceolate, 3 to 6 cm. long, 1 to 2 cm. broad, obtuse or acute, crenate-dentate to entire, subhirtellous above, paler and whitish-tomentulose beneath, rather strongly reticulate-nerved; petioles about 0.5 cm. long: inflorescence a subcorymbose rather leafy panicle: heads many, sessile or nearly so, 12 to 14 mm. high, usually 12-flowered: involucre narrowly campanulate or subcylindric; bracts of the involucre about 7- seriate, strongly unequal, imbricated, sparingly pubescent, ciliate, striate, pale with greenish nerves, or purplish; the outer bracts ovate-oblong, mucronate, strongly ciliate, the inner lance-linear, acute: flowers somewhat exceeding the involucre: pappus silvery white, 6 mm. long, about as long as the white or purplish-tinged corolla: achenes 3 mm. long, pubescent.— Guatemala. Department of Baha Vera Paz: Sierra de las Minas, altitude 1,11:8 m., 3 March, 1007, W. A. Keller man, no. 6127 (hb. Field Mus.). In leaf-outline B. Kellermanii resembles B. cylindrica and B. Pringlei Gray, but it is amply distinct from both these species in the nature of the inflorescence, tomentum, and in the technical characters of the head. Egletes viscosa Less. Syn. Comp. 252 (1832). Cotula viscosa L. Sp. PI. 892 (1753); Willd. Sp. PI. iii. 2167 (1800). This species was based on material collected by Houston in the region of Vera Cruz, Mexico. Specimens obtained at La Purga, 31 kilometers southwest of the City of Vera Cruz, 27 January, 1906, J. M. Greenman , no. 257 (hb. Field Mus.), agree well with the early although brief descriptions of the above species, and are confidently referred to it. The species is of rather wide distribution, occurring in southern Mexico, the West Indies and, according to Hemsley, in South America; it is, moreover, well characterized by its viscid-hirsute character and somewhat lyrate or pinnately incised foliage, suggesting vigorous forms of Senecio viscosus L. In 1890 and again in 1892 Mr. C. G. Pringle collected on river banks at Las Palmas, Mexico, an Egletes which was referred to E. viscosa Less. The latter of the two collections made by Mr. Pringle was distributed by clerical error as 11 Egletes viscida Less.” Mr. Pringle’s specimens differ in several particulars from Lessing’s species. Moreover, they do not correspond to any known species of the genus, hence they may be characterized as follows: Egletes Pringlei Greenman, sp. nov. Annual: stem erect or essentially so, simple or branched from near the base, somewhat geniculate above, viscid-hirsute: leaves ovate to more or less obovate, 1.5 to 7.5 cm. long, one- half to two-thirds as broad, thin or membranous, rather coarsely 266 Field Columbian Museum — Botany, Vol. II. and unequally sinuate-dentate, contracted below into a narrowly winged petiole and subamplexicaul by a slightly auricular base: inflorescence terminating the stem and branches in a paniculate cyme: heads 4 to 5 mm. high, radiate: ray-flowers many- seriate; corollas minute, 1.5 to 2 mm. long, less than 0.5 mm. broad: disk-flowers numerous; corollas about 1 mm. long, 4-5-toothed; tube on the outer surface glandular-pilose: achenes slightly compressed, produced above into a somewhat irregular saucer-shaped subcartilaginous pappus.— Mexico. State of San Luis Potosi: river banks, Las Palmas, 4 June, 1890, C. G. Pringle, no. 3531 (hb. Field Mus.); and in the same locality, 18 June, 1892, C. G. Pringle, no. 4101 (hb. Field Mus.). E. Pringlei is readily distinguished from E. viscosa Less, by the ovate or obovate undivided leaves, the more numerous heads, shorter hairs on stem and branches, and finally by the smaller narrower rays, the more conspicuously flaring pappus, and the less conical receptacle. Erigeron pacayensis Greenman, sp. nov. Suffruticose: stems erect or ascending, branched, 1 to 1.5 dm. high, pubescent with upwardly appressed or but slightly spreading hairs: leaves narrowly linear-oblanceolate, 1 to 2 cm. long, 1 to 3 mm. broad, acute or obtusish, entire or bearing a single tooth on one or both margins, gradually narrowed below to a subpetiolate base, sparingly pubescent on either surface to nearly glabrous: heads few, small, 5 to 6 mm. high, less than 1 cm. in diameter including the rays, terminating the stem and branches on long slender appressed-pubescent peduncles 6 cm. or less in length: involucre subcampanulate; bracts of the involucre about 3-seriate, unequal, lance-linear, acute, appressed-pubescent, more or less purplish; the outer bracts shorter: ray-flowers 3-seriate, many; rays narrow, white or roseate: flowers of the disk numerous: pappus bristles slender, 2 to 2.5 mm. long: achenes pubescent.— Guatemala. Depart¬ ment of Amatitlan: crater of the Volcano of Pacaya, altitude 2,500 m., 6 January, 1907, W. A. Kellerman, no. 6111 (hb. Field Mus., and hb. Gray). The species here proposed has its affinity with Erigeron Ervend- bergii Gray, and *E. irazuensis Greenman. From the former it differs in having smaller heads, appressed instead of spreading hairs on the involucre, more unequal involucral bracts, etc. Although similar in habit to E. irazuensis, yet it differs in several particulars, namely in having narrower and less pubescent leaves, also in the appressed pubescence on the stem and pedun¬ cles, as well as in other details. I am indebted to Mr. H. H. Bartlett of the Gray Herbarium for a critical comparison of Professor Kellerman’s plant with the type of E. irazuensis. * By oversight published as Erigeron irazuense.

Stem terete, sulcate, hirtellous-puberulent with crisp sordid hairs: leaves elliptic-lanceolate to oblanceolate, 1 to 3.5 cm. long, 2 to 8 mm. broad, acute or obtuse, sharply dentate with unequal and somewhat spreading teeth, narrowed at the base into a short petiole, at first slightly puberulent above but soon becoming glabrous, persistently hirtellous-pubescent beneath, subtrinervate and rather prominently reticulate-veined: in¬ florescence a terminal subcorymbose cyme: heads of the pistil¬ late plant numerous, 6 to 7 mm. high: involucre subcampanu- late; bracts of the involucre unequal, 4-5-seriate, linear-ob-long, obtuse or rounded at the tip, more or less purplish on the back and ciliate towards the apex, the outermost shortest: flowers 18 to 24; pappus about 4 mm. long, slightly tawny, exceeding the slender corolla-tube: mature achenes 1.5 mm. long, glabrous: staminate plant not seen.— Guatemala. De¬ partment of Solala: Volcano of Atitlan, 16 February, 1906, W. A. Kellerman, no. 5356 (hb. Field Mus.). In leaf-outline Baccharis Kellermanii suggests B. thesioides HBK., but the two species are amply distinct in habit, inflorescence, involucral details, and in the character of the surface of stem and leaves. Gnaphalium brachyphyllum Greenman, sp. nov. An herbaceous perennial, lanate-tomentose throughout: stems several, erect or nearly so, from a ligneous base, 1 to 2 dm. high, slender, leafy: leaves linear-oblong or slightly oblanceolate, 0.5 to 1.5 cm. long, 1 to 4 mm. broad, obtuse, entire, slightly repand-margined, sessile and semiamplexicaul, densely lanate- tomentose on both surfaces: inflorescence terminating the stems in rather dense cymes: heads 4 to 5 mm. high: involucre sub- campanulate, tomentose at the base otherwise essentially glabrous; bracts of the involucre 3-4-seriate, pale stramineous, the outer ovate and about 3 mm. long, the inner linear-lanceolate, 3.5 to 4 mm. long, greenish at the base especially along the median line: pistillate flowers numerous: perfect flowers 6 to 10: pappus caducous: achenes glabrous, 1 mm. long, reddish.—• Guatemala.

Baker, no. 2154 (hb. Field Mus.); Herradura, 24 August, 1905, H. A. Van Hermann, no. 705 (hb. Field Mus.). The species here described resembles W. reticulata DC.; but the oblong or oblong-lanceolate outline of the leaves with their distinctly pinnate venation and entire or slightly crenate margin, the shorter involucral bracts, and the peculiar uncinate-tipped pales amply distinguish it from the De Candolle species. Perymenium Goldmanii Greenman, sp. nov. Stem terete or slightly tetragonal, striate, strigillose: leaves opposite, petiolate, ovate-lanceolate, 3 to 8 cm. long, 1 to 4 cm. broad, acuminate, acute, dentate to subentire, rounded to sub- cordate at the base, scabrous above and becoming slightly rugose in age, hirsutish-pubescent beneath, green on both sides, 3-nerved from near the base; petioles 3 to 10 mm. long; inflores¬ cence terminating the stem and the horizontally spreading or ascending lateral branches in rather dense cymose clusters: heads numerous, small, 6 to 7 mm. high, about 3 mm. in diameter, radiate; primary and secondary peduncles short, usually less than 2 cm. in length, appressed-pubescent; involucre subcampan- ulate; bracts of the involucre unequal, 2-3-seriate, the outer shorter, ovate to ovate-oblong, 3 to 4.5 mm. long, acute or ob¬ tuse, externally strigillose, ciliate: ray-flowers commonly 5; rays lemon-yellow: disk-flowers about 20: pappus of numer¬ ous unequal setae: mature achenes laterally compressed or somewhat 3-angled, about 2.5 mm. long, ciliate or narrowly winged, transversely rugose under a lens and slightly pubes¬ cent on the surface especially in the upper half.— Mexico. State of Campeche: Apazote, near Yohaltun, 27 to 29 December, 1900, E. A. Goldman, nos. 487, 502 (hb. U. S. Nat. Mus., and hb. Field Mus.). The affinity of the species here described is with P. micro- cephalum Schz. Bip., and P. gracile Hemsl., but it differs from the former by the larger leaves and from the latter in foliar and achenial characters. The narrowly winged achenes of P. Gold¬ manii suggest P. gymnolomoides DC., but that species has smaller leaves, shorter petioles and fewer heads in the inflorescence. Notoptera Gaumeri, n. comb. Salmea Gaumeri Greenm. in Field Col.

The homogamous heads, the short accumbent involucre, the characteristic ear-like wing on the posterior pappus-awn, 270 Field Columbian Museum — Botany, Vol. II. and the habit of the plant render it a congener of Professor Urban’s recently published genus Notoptera, Symb.

A careful examination of a considerable number of specimens representing this species shows a marked variation in the form and size of the outer spreading subfoliaceous involucral bracts. These vary from spatulate to lanceolate or linear and from 3 to 12 mm. in length. There is also some diversity in the size of the rays. The following specimens are here referred.—• Mexico.

State of Campeche: Canasayal, 12.5 km. above Champotan river, 12 December, 1900, E. A. Goldman , no. 448 (hb. U. S. Nat. Mus., and hb. Field Mus.). The plant here described in the appearance of the involucre suggests some of the Galinsogece, particularly Calea and Geissolepis, and certain of the Helenioideoe, especially Jaumea. The paleaceous receptacle, the dorsally appressed achenes, and the character of the pappus place it, however, with the Coreop- side (E. The genus is named in honor of its collector Mr. Edward A. Goldman of the United States National Museum. Bidens Urbanii Greenman, sp. nov. Perennial: stem ligneous, twining; branches terete, minutely striate, glabrous, or puberulent in decussating lines: leaves opposite, petiolate, triangular-ovate in general outline, exclusive of the petiole 3 to 7 cm. long, 2 to 6 cm. broad, bi-tri-pinnatisect with narrowly lanceolate acute submucronate-dentate divisions, glabrous to minutely and sparingly hispidulous on the upper surface, paler and glabrous or essentially so beneath; petioles slender, 0.5 to 3.5 cm. long: inflorescence in terminal more or less leafy paniculate cymes; the individual axillary pedunculate cymes exceeding the leaves: heads radiate, during anthesis 8 to 10 mm. high, including the rays 2 to 2.5 cm. in diameter: invo¬ lucre biseriate; the outer bracts of the involucre herbaceous, lance-linear to narrowly spatulate, acute or obtusish, reflexed, glabrous or slightly puberulent; inner involucral bracts thin, dark brown or chocolate-colored with yellowish 'subscarious margins: ray-flowers usually 5, sterile; rays narrowly oblong, about 1 cm. long, obtuse or retuse, pale yellow, about 7-nerved 272 Field Columbian Museum — Botany, Vol. II. with dark brown or blackish nerves: disk-flowers 20 to 25: mature achenes of the fertile flowers linear, 12 mm. or less in length, erect or somewhat recurved, 2-4-awned with relatively short retrorsely barbed persistent pappus-awns, striate, 2-4- angled in cross-section, ciliate along the angles otherwise glabrous. — Porto Rico.

Goldman , no. 468 (hb. U. S. Nat. Mus.; fragment and photograph in hb. Field Mus.). This species has its affinity with a small natural group of plants to which B. rubifolia HBK, B. tereticaulis and B. coreopsidis DC. belong, but the smooth or lineate-puberulent stem and branches, the pinnatisect leaves with their numerous narrow divisions, the nature of the pubescence, and certain technical characters of the head seem to the writer to warrant its specific rank. B. Urbanii is apparently most closely allied to B. Coreop¬ sidis, var. (?) incisa DC. v. 599 (1836) ( Coreopsis incisa Ker- Gawl. Bot. Reg. t. 7), but here again a careful comparison with the original description and illustration shows several important differences. Calea Pringlei Rob., var. rubida Greenman, var. nov. Leaves short-petiolate, ovate, 1.5 to 3 cm. long, two-thirds as broad, densely tomentose beneath; petioles 2 to 4 mm. long, tawny-pubescent: involucral bracts elliptic-oblong, red- dish-margined.— Mexico. State of Vera Cruz: on hillsides near Chavarillo, 7 September, 1906, C. R. Barnes, C . J.Chamberlain & W. J. G. Land, no. 4 (hb. Field Mus., and hb. University of Chicago). Differs from the type of the species chiefly in the short but distinctly petioled leaves, and by the slightly narrower and reddish-margined involucral bracts. Florestina Liebmannii Schz. Bip., in herb. Stem erect or somewhat ascending from an indurated base, 3 to 5 dm. high, simple or sparingly branched, terete below, striate-angled above, substrigillose and more or less closely beset with stipitate glands: lower leaves opposite, simple, petiolate, narrowly lanceolate-oblong, 2 to 3.5 cm. long, 4 to 12 mm. broad, obtuse or acute, entire or occasionally few-dentate, obtuse at the base, substrigose-hispid on both surfaces, 3-nerved; petioles 0.5 to 1.5 cm. long, hispid-pubescent intermixed with stipitate-glandular hairs; the upper stem-leaves alternate and gradually reduced to linear bracts: inflorescence terminating the stem in a glandular-pubescent subcorymbose cyme: heads homogamous, 8 to 10 mm. high: involucre sub turbinate; bracts of the involucre 8, uniseriate or essentially so, elliptic-oblong to obovate-oblong, 4 to 5 mm. long, 2 to 3 mm. broad, rounded at the apex, scarious-margined and more or less erose-ciliate, ap- pressed-puberulent on the outer surface: flowers 12 to 14: pappus of 8 obovate or broadly spatulate hyaline-scarious pointless Dec. 1907.

Field Mus.); along the shore, north of the City of Vera Cruz, 24 January, 1906, J. M. Greenman , no. 114 (hb. Field Mus., and hb. Gray). The general habit and simple leaves of this species suggest a relationship with Palafoxia or Polypteris, but the technical characters of the involucre, pappus, corolla and style-branches place it rather with Florestina. The affinity of the plant, as well as its specific rank, was first recognized by Schultz Bipontinus, and subsequently by the late Professor F. W. Klatt, but the name seems not to have been hitherto published. I am indebted to Professor Eug. Warming for the identifica¬ tion of my no. 114 with the Liebmann plant in the Botanical Museum at Copenhagen. Tagetes jaliscensis Greenm., var minor Greenman, var. nov. Leaves 3 cm. or less in length, about two-thirds as broad: heads 1.3 to 1.8 cm. high; involucre 1 to 1.4 cm. long: mature achenes 7 to 7.5 mm. in length.— Mexico. State of Oaxaca: Cercainas de Oaxaca, altitude 1550 m., 8 November, 1906, C. Conzatti, no. 1516 (hb. Field Mus.). The chief distinguishing characters separating var. minor from the species are the smaller leaves, shorter involucre and flowers. Dysodia (§Gymnolaena) oaxacana Greenman, sp. nov. Shrub: stem and branches covered with a grayish bark; ulti¬ mate branchlets terete, somewhat striate, greenish or reddish- brown, minutely pubescent in decussating lines: leaves opposite, sessile or essentially so, lanceolate, 1 to 4 cm. long, 4 to 11 mm. broad, acute, finely serrulate, narrowed below to an entire or occasional subsetiferous subpetiolate base, pellucid-punctate, slightly pubescent on both surfaces under a lens especially on the midrib of the upper surface, or glabrous: heads few, hetero- gamous, 1.5 to 2 cm. high, terminating the stem and branches on minutely bracteate 1.5-5 cm.-long glabrous peduncles: involu¬ cre at first narrowly campanulate or subcylindric, often split on one side, 12 to 14 mm. long, (7-) 8-dentate, naked or essentially so at the base, glabrous, bearing several linear-elliptic glands, later separating into more or less distinct lance-linear bracts; teeth, or the terminal portion of the individual bracts, short, triangular, acute, pubescent-tipped: ray-flowers commonly 8; rays including the slender tubular portion 1.5 cm. long, 4 to 5 mm. broad, deep orange-red: disk-flowers about 30: pappus of numerous lacerate-fimbriate scales, tawny: achenes 6 mm. long, pubescent.— Mexico. State of Oaxaca: Almoloyas, 274 Field Columbian Museum — Botany, Vol. II. altitude 800 m., 25 December, 1906, C. Conzatti, no. 1653 (hb. Field Mus. Catalogue no. 195851; fragment in hb. De Candolle). I am indebted to Dr. Casimir De Candolle for a detailed com¬ parison of Professor Conzatti’s plant with the type of Dysodia serratifolia DC. From this species, as pointed out by Dr. De Candolle, D. oaxacana differs in having smaller leaves, few heads- instead of a multiflorous corymb, and pubescent-tipped invo- lucral bracts. To this natural group also belong D. integrifolia Gray, and D. Seleri Rob. & Greenm. From the former the species described above is readily separated by the pubescent branchlets and puberulent leaves; and from the latter by the presence of pellucid glands on leaves and involucre.

Dr. Emrick’s specimens show the uppermost leaves to be ovate, acuminate, acute, entire or remotely mucronate-denticulate and abruptly narrowed below the middle to an acute base. The mature achenes, moreover, are 4 mm. in length, pubescent and strongly striate. Schistocarpha platyphylla Greenman, sp. nov. Stem terete, striate, glabrous or slightly pubescent above: leaves opposite, petiolate, ovate, 10 to 25 cm. long, 6.5 to 22 cm. broad, acuminate, acute, sinuate-dentate, subcordate to cuneate at the base and decurrent on the subconnate petioles, 3-nerved, sparingly pilose on both surfaces, slightly paler beneath, thin and membranous: inflorescence a terminal subcorymbose many¬ headed pubescent panicle; bracts linear, subsetaceous: heads- 7 to 8 mm. high: involucre narrowly campanulate; bracts of the involucre 3-seriate, lance-oblong, 3 to 5 mm. long, 1 to 1.5 mm. broad, obtuse or obtusish, pale stramineous, striate, glabrous: pales hyaline, subcuneate, about 3 mm. long, irregularly 3-5- toothed: pistillate flowers usually 13; corollas tubular; tube 2 mm. long, externally pubescent: perfect flowers 14 to 18;. corollas about 5 mm. long, slightly exceeding the pappus; tube puberulent, gradually ampliated above into a 5-toothed limb: mature achenes 1 mm. long, glabrous or sparingly puberulent under a strong lens.— Guatemala.

Gray, and hb. Inst. Physico-Geogr. Costa Rica). Senecio (§ Terminales) serraquitchensis Greenm. Suffruticose: stem above tawny-tomentose: leaves petiolate, oblong-lanceolate to somewhat oblong-obovate, 1.2 to 2.5 dm. long, 3 to 9 cm. broad, mucronate-acute, slightly sinuate, remotely cartilaginous-denticulate, narrowed below to the tomentulose 2.5 to 6.5 cm.-long petiole, at first tomentulose on both surfaces especially on the midrib and lateral nerves beneath, but soon glabrate and rather strongly reticulate-veined: inflorescence abruptly terminating the stem in one or more long-pedunculate compound many-headed corymbs: heads about 1 cm. high, radiate: involucre barely calyculate with minute bracteoles; bracts of the involucre 8, narrowly oblong, about 4 mm. long, obtuse, turning blackish in drying: ray-flowers 5; ligules short, 4-nerved; tube shorter than the pappus: disk-flowers 5 or 6; corollas rather deeply 5-lobed: achenes glabrous.— Monogr.

Senecio (§Terminales) uspantanensis Greenm. Monogr. Se¬ necio, I Th. 26 (1901) & in Engl. Bot. Jahrb. xxxii. 22 (1902). 5 . Ghiesbreghtii , var. uspantanensis Coulter, Bot. Gaz. xx. 52 (1895), in part, as to Heyde & Lux, no. 3,368 (hb. Gray) and Botteri, nos. 609, 820 (hb. Gray). Although 5 . uspantanensis is similar in habit to 5 . serraquit¬ chensis, yet the former differs markedly in its glabrous stem and foliage, longer and fewer (5 instead of 8) involucral bracts. Trixis Pringlei Rob. & Greenm. Proc. Am. Acad. xl. 10 (1904). Specimens collected by Professor C. Conzatti at De Almoloyas d Sta. Catarina, Oaxaca, Mexico, at an altitude of 1,000 m., 26 December, 1906, no. 1,646 (hb. Field Mus.) agree well with specimens secured by Mr. Pringle on which the species was based, except the leaves in the Conzatti plant have a maximum breadth of 2.5 centimeters. Jungla Pringlei Greenman, sp. nov. Stem terete, pubescent: leaves petiolate, orbicular-ovate, cordate, 7-9-lobed, hirtellous-puberulent and rather strongly reticulate-nerved above, crisp-hirsute-pubescent and atomi- ferous-glandular beneath; lobes ovate-triangular, dentate, mu- Dec. 1907.
