 Dr. N. L. BRITTON has kindly submitted to the writer for identifica- 
 tion a very unusual assemblage of Senecionea from Cuba collected by 
 Mr. J. A. SHAFER in 1909 and 1910. The results of a study of this 
 remarkable series of specimens are recorded as follows:

 The species is well marked on account of the strongly discolorous 
 leaves, which are densely tawny pubescent on the under surface, and by 
 the decurrence of the petioles on the stem thus causing the younger 
 branches to be subancipitally angled, or strongly keeled, hence the 
 specific name. 
 
 Senecio cubensis Greenman sp. nov.

 ber, 1910, /. A. Shafer, no. 8223 (hb. Field Museum, cat. no. 294805, and

 A species somewhat similar to Senecio trichotomus Greenm., but 
 differs in having broader leaves and leafy open few-headed cymes. 
 
 Senecio leucolepis Greenman, sp. nov. 
 
 Suffrutescens 34 dm. altus; caule tereti glabro; ramis ramulisque

 Bot. Garden). 
 
Nov., 1912. CUBAN SENECIONEJE GREENMAN 325 
 
 The general aspect of this species is similar to Senecio Brittonii 
 Greenm., but it differs in having an essentially sessile inflorescence, 
 fewer heads, shorter and densely white-pubescent involucral bracts, and 
 in the characters of the corolla. 
 
 Senecio pachylepis Greenman, sp. nov. 
 
 Frutex 1.5-2 m. altus; caule lignescente; ramis ramulisque teretibus 
 glabris vel juventate dense cano-tomentosis; foliis alternis petiolatis 
 oblongo-obovatis vel oblanceolatis 3.5-10 cm. longis 1.5-3.5 cm - latis 
 utrinque glabris ad apicem obtusis sinuato-dentatis ad basin integris 
 marginibus plus minusve revolutis; petiolis usque ad 1.5 cm. longis; 
 inflorescentiis terminalibus cymosis sessilibus; capitulis discoideis caly- 
 culatis; involucri squamis 8 lanceolatis vel lanceolato-oblongis 4-5 mm. 
 longis obtusis vel acutis glabris vel parce arachnoideo-tomentosis, 
 bracteolis calyculatis 5 spathulatis 2-3.5 mm - longis i mm. latis obtusis 
 crassiusculis ; floribus 10-12 flavibus; pappi setis fulvis; achaeniis 
 striatis hirtellis. Along rocky river trail, Rio Yamaniguey to Camp 
 Tao, Oriente, Cuba, 22-26 February, 1910, /. A. Shafer, no. 4008 
 (hb. Field Museum, cat. no. 294785, type, and hb. N. Y. Bot. Garden). 
 
 In habit and foliar characters this species resembles S. eriocarphus 
 Greenm., but differs in having a close matted tomentum on the young 
 branches, glabrous leaves, smooth or slightly arachnoid involucral 
 bracts, and finally in having strongly spatulate and thickened calyc- 
 ulate bracteoles. The plant cited under the above number has been 
 referred to S. plumbeus Griseb.; but from that species, which it resembles 
 in habit and in foliar characters, it is readily distinguished by the 
 shorter petioles, blunter leaves, sessile crowded terminal inflorescence, 
 and the spatulate thick calyculate bracteoles. 
 
 Senecio pachypodus Greenman, sp. nov. 
 
 Frutex 1-2 m. altus; ramis ramulisque cortice verrucoso tectis gla- 
 bris ad apicem foliaceis; foliis alternis numerosis coriaceis lineari-

 brevi-acuminatis obtusis penicillatisque glabris, basi crassis ; floribus 5 ; 
 corollis 5-6 mm. longis; pappi setis albis; achaeniis columnaribus 2 mm. 
 longis cano-pubescentibus. - Collected at Camp La Gloria, south of 
 Sierra Moa, Province of Oriente, Cuba, 24-30 December, 1910, /. A. 
 Shafer, no. 8186 (type in hb. N. Y. Bot. Garden; fragment and photo- 
 graph in hb. Field Museum, cat. no. 300835). 
 
326 FIELD MUSEUM OF NATURAL HISTORY BOTANY, VOL. II 
 
 A plant of quite unusual habit in this genus. The numerous linear 
 leaves, tufted at the ends of the branches, and the naked stem and 
 lower portion of the branches, roughened by the persistent bases of old 
 leaves, render it of striking appearance, which indeed at first glance is 
 not unlike a coniferous growth.

 The plant here described belongs to the Senecionece and is related 
 to the genus Senecio from which, however, it differs in having the bracts 
 in three or four series and in the obtuse style-branches. It seems to be 
 related on the one hand to Senecio and on the other to Culcitium, but 
 
328 FIELD MUSEUM or NATURAL HISTORY BOTANY, VOL. II 
 
 amply distinct from both. The angulate stem, the large thick almost 
 leathery leaves with a dense permanent tomentum on the tinder surface, 
 combined with the large heads and many bracted involucre, give the 
 plant a most striking appearance quite distinct from anything known 
 to the writer. The genus is dedicated to the keen and indefatigable col- 
 lector for the New York Botanical Garden Mr. J. A. SHAFER.

 OTHER SPERMATOPHYTES, CHIEFLY FROM 
 
 MEXICO AND CENTRAL AMERICA. 
 
 By J. M. GREENMAN. 
 
 The diagnoses and notes following are the results of critical study 
 in the determination of several collections of plants which have been 
 received from time to time during the last few years at the Field Museum 
 of Natural History for identification. Particularly valuable series 
 have been received from Professor CASSIANO CONZATTI, from the late 
 Professor W. A. KELLERMAN, from Mr. CHARLES R. ORCUTT, and from 
 the late Professor CHARLES R. BARNES and Dr. W. J. G. LAND. These 
 collections while not containing a large percentage of new plants do 
 include many which belong to recently published and hence little- 
 known species; thus there are here introduced several brief notes, relat- 
 ing to additional localities for such species, which it is hoped may be 
 helpful in tracing their geographical distribution. 
 
 TRADESCANTIA ANGUSTIFOLIA Rob. Proc. Am. Acad. xxvii. 185 (1892). 
 The type of this species is perfectly matched by specimens col- 
 lected on the Cerro de San Antonio de la Cal, State of Oaxaca, 
 Mexico, altitude 1700 m., 18 August, 1907, C. Conzatti, no. 1995 
 (hb. Field Museum). 
 
 Ficus SUBROTUNDIFOLIA Greenm. Proc. Am. Acad. xli. 237 (1905). 
 Specimens agreeing in all essential details with this species were 
 collected at Chichen Itza, State of Yucatan, Mexico, 28 January and 
 10 February, 1901, E. W. Goldman, no. 553 (hb. Field Museum). Dr. 
 Geo. F. Gaumer's, no. 599, coll. of 1905 from Yucatan seems also to 
 be conspecific. 
 
 PHORADENDRON ROBINSONII Urban, Engl. Bot. Jahrb. xxiii. Beibl. 
 
 Ivii. 4 (1897). 
 
 This species, which was based on no. 6272 of Mr. C. G. PRINGLE'S 
 Plantce Mexicans, has been collected at San Nicolas, Tehuacan, State 
 of Puebla, Mexico, altitude 2000 m., 22 June, 1908, C. Conzatti, no. 
 2199 (hb. Field Museum). The species is well marked and one of the 
 most attractive of the genus.

 ARISTOLOCHIA OAXACANA Eastwood, Proc. Am. Acad. xliv. 603 (1909). 
 Complete flowering and fruiting specimens secured by Professor C. 
 Conzatti at Camino Montelobos, Dto. Nochixtlan, De Rancho Nopalera 
 a Huitzo, State of Oaxaca, Mexico, altitude 2000 m., 23 June, 1907, 
 no. 1838 (rib. Field Museum) have been compared with the type of the 
 above species and accord in all essential details. The present collec- 
 tion records another station in determining the distribution of a very 
 interesting and distinct species.

 Colima, 24 October, 1910, C. R. Orcutt, no. 4587 (hb. Field Museum cat. 
 no. 283404). 
 
 A species similar to C. Moquini Guillem., but with smaller yellowish- 
 green leaves, reddish-brown stem and inflorescence, and with uniformly 
 pale-stramineous instead of more or less fuscous sepals, and with a 
 sessile instead of stipitate utricle.

 APOPLANESIA PANICULATA Presl Symb. Bot. i. 63, t. 41 (1831). 
 
 The punctate leaflets, persistent samara-like calyx-lobes and short 
 glandular fruit render this species, although apparently somewhat 
 rare, an easily recognized one. It is well represented by specimens 
 secured by Dr. G. M. Emrick at Tecoman, State of Colima, Mexico, 
 November, 1906, nos. 153, 154 (hb. Field Museum), and by collections 
 made at Manzanillo, Mexico, 1890-91, Dr. Edward Palmer, nos. 967, 
 13730, an< i X 8io (hb. U. S. Nat. Museum). These collections extend 
 the known geographical range of the species considerably to the north 
 of previously recorded localities.

 This species is named in honor of Dr. GEORGE F. GAUMER who first 
 collected the plant in 1888. Dr. GAUMER states that it is a tree often 
 becoming sixty feet in height and is abundant in the brush and forest 
 lands about Izamal, where it is known by the native name of Xcitinche.

 this species in the Gray Herbarium and with material secured at San 
 Jose del Cabo, Lower California, 9 September, 1890. The species has 
 not been recorded hitherto outside of Lower California. Notwith- 
 standing the considerable remoteness of Professor CONZATTI'S station 
 from the peninsular localities for the species there can be no doubt of 
 the identity of the Oaxaca specimens with the above species.

 In general appearance this species resembles M. arbor eus Cav., but 
 it differs in having uniformly shorter petioles and fully twice larger

 HBK., but from the original description of that species it differs marked- 
 ly in foliar and calyx characters.

 Specimens of Conzatti's no. 1586 were sent to the Kew Herbarium 
 for comparison with Bumelia subsessiliflora Hemsl. with which species 
 the plant in question seemed from description to be most closely related. 
 Mr. N. E. BROWN has very kindly made a careful comparison for me 
 and states that the Conzatti plant is not only specifically different 
 from B. subsessiliflora, but that it is distinct from all the species of 
 Bumelia represented at Kew. From the several characters noted by 
 Mr. BROWN as distinguishing B. eriocarpa from B. subsessiliflora may

 be mentioned the following: thicker and much more conspicuously 
 tomentose stem, thicker and more coriaceous leaves which are persistent- 
 ly tomentose (not glabrous) when old, and finally slightly longer and 
 thicker pedicels and rather larger flowers.

 This species is well-marked on account of the obovate-spatulate foli- 
 aceous calyx-segments, the green or greenish corolla, and short straight 
 or slightly incurved spurs. It is perhaps nearest allied to the little- 
 known Halesia elongata Don, but that species is said to have linear- 
 lanceolate leaves.

 This species was described from plants grown in the garden of the 
 University of Vienna from seeds which, it is stated, were sent from 
 England in 1814; the seeds, it is said moreover, came originally from 
 China. The correspondence of the specimens at hand with the de- 
 scription and illustration in JACQUIN'S Eclogice is so strikingly coincident 
 there can be little doubt that we are dealing with one and the same 
 species. It is quite possible that there may have been some mixture 
 of the seeds grown, as it is a well known fact that Jacquin at this time 
 was growing many American plants in Vienna, and it is not unlikely that 
 he may have confused certain American importations with the seeds 
 which were supposed to have come indirectly from China. At all 
 events several complete specimens at hand agree in all essential details 
 with the above species, as it is characterized and illustrated, and the 
 writer has no hesitation in referring thereto the following Mexican 
 plants. State of Yucatan: Merida, 20 August, 1865, A. Schott, no.

 Excellent flowering specimens of a very attractive Mexican shrub 
 have been communicated to the writer by Professor C. CONZATTI for 
 identification; these were compared recently at the Gray Herbarium 
 with the type of Miss EASTWOOD'S Bourreria obovata and prove to be 
 identical. Only two days subsequent to the date of publication of 
 Miss EASTWOOD'S paper, Mr. BRANDEGEE issued a paper dealing with 
 a collection of plants made in Mexico by Dr. C. A. PURPUS and among 
 other novelties described Beurreria strigosa founded on Purpus' no. 
 3360. This material is almost the counterpart of the type of B. obovata, 
 hence by the rule of priority B. strigosa must give way to the earlier 
 published name. In addition to the material cited in the above publica- 
 tion the following may be recorded: Cuesta de Quiotepec, District of

 Habitally this species resembles Lantana macropoda Torr. and has 
 often been confused with it, but may be distinguished readily by the 
 larger, acuminate and sharply dentate leaves, coarser and more scattered 
 pubescence.

 which a part of the material above cited has been hitherto confused. 
 The more striking characters distinguishing L. albicaulis from L. umbel- 
 lata and other species of the immediate group to which it belongs are its 
 smooth ashy white stem and branches, puberulent branchlets, dark 
 green elliptic-lanceolate leaves which are but slightly pubescent on 
 both surfaces.

 The species here proposed has its affinity with L. lupulina Cham., 
 L. umbellata Cav., L. substrigosa Turcz., and L. nutans Rob. & Greenm., 
 but it is amply distinct and easily recognized among all the known 
 species of the genus on account of the large broadly ovate leaf -blade, 
 which is cordate or abruptly contracted at the base, rugose and hirsute- 
 hispid above and sub-tomentose beneath, and glandular hairs inter- 
 mixed with a spreading hirsute pubescence on stem, petioles and 
 peduncles.

 The affinity of this species is apparently with S. carulea Moc. & 
 Sesse and S. Seleriana Loes. From the former it differs in the low 
 stature, small leaves, shorter and reddish to dark purple flowers and 
 distinctly racemose inflorescence; from S. Seleriana it differs in the 
 color of the flowers and in the exserted stamens.

 The species here proposed belongs to the same group as Ruellia 
 Bourgaii Hemsl. and R. pulcherrima T. Anders. From the former it 
 differs in the outline, size, pubescence and texture of the leaves, smaller 
 flowers, more lanceolate calyx-divisions, pubescent ovary and fewer 
 ovules; from R. pulcherrima it differs in having larger leaves, shorter 
 calyx, the absence of stipitate glands, and in the more conspicuously 
 ventricose and larger corolla.

 But for the presence of a reduced pappus the plant here described 
 might be referred equally well to Gymnocoronis, and habitally it re- 
 sembles G. subcordata DC., but differs in involucral and achenial char- 
 acters. In most cases, however, the pappus is present in the form of 
 one to three papillose-clavate much reduced setae, hence its affinity 
 seems rather to be with Adenostemma.

 A re-examination of the material referred to Perymenium grande 
 Hemsl. by ROBINSON and GREENMAN in their revision of this genus 
 shows that the variety strigillosum may be clearly differentiated from 
 Mr. HEMSLEY'S species by the appressed or strigillose pubesence on 
 stem, branches, inflorescence and petioles, by the uniformly shorter 
 and narrower involucral bracts, and by the thicker leaves. It seems 
 therefore best to regard this plant as a species rather than a variety, 
 hence it is here raised to specific rank and a description appended.

 In general appearance L. adenotrichum resembles L. glabrum Hemsl., 
 var. hypoleucum Greenm., but differs in the more pointed involucral 
 bracts, the presence of stipitate-glandular hairs in the inflorescence, and 
 pubescent achenes.

 The writer has at hand but a leaf and a part of an inflorescence yet 
 the plant belongs evidently to the section Terminates Greenm. and is 
 allied to S. arborescens Seem, and S. copeyensis Greenm. From both 
 these species, however, S. Orcuttii is distinguished readily by the deeply 
 pinnately parted almost compound leaf and large heads.

 Good specimens of this species were collected at Cherubusco, 
 Distrito Federal, Mexico, 4 October, 1910, C. R. Orcutt, no. 4283 (hb. 
 Field Museum, cat. no. 282479). The plant is well established at this 
 station, but the species seems not to have been reported hitherto from 
 Mexico.
