By J. M. GREENMAN.

Dr. N. L. Britton has kindly submitted to the writer for identifica-

tion a very unusual assemblage of Senecionece 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:

324 Field Museum of Natural History — Botany, Vol. II

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.

Caulis lignescens ; ramulis ultimis teretibus tomentulosis ; f oliis alter-

nis petiolatis lanceolatis vel lanceolato-oblongis 3-9 cm. longis 1-2.5 cm.

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

hb. N. Y. Bot. Garden).

A species somewhat similar to Senecio trichotomiis Greenm., but

differs in having broader leaves and leafy open few-headed cymes.

Senecio leucolepis Greenman, sp. nov.

Suffrutescens 3-4 dm. altus; caule tereti glabro; ramis ramulisque

tomentosis; f oliis alternis brevi-petiolatis lanceolatis vel anguste lan-

Bot. Garden).

Nov., 191 2. Cuban Senecione^e — 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 nim. longis 1 mm. latis obtusis

(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 foment um 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-

lanceolatis 5-8 cm. longis 2-4 mm. latis margine integris revolutisque

basi gradatim angustatis supra glabris subtus dense albo-lanatis ;

inflorescentiis terminalibus paucicapitatis glabris; capitulis 8-10 mm.

brevi-acuminatis obtusis penicillatisque glabris, basi crassis; floribus 5;

corollis 5-6 mm. longis; pappi setis albis; achasniis columnaribus 2 mm.

longis cano-pubescentibus. — Collected at Camp La Gloria, south of

Sierra Moa, Province of Oriente, Cuba, 24-30 December, 19 10, /. 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 or 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.

Senecio rivalis Greenman, sp. nov.

Verisimiliter arborescens; caule tereti glabro vel juventate arach-

noideo-tomentuloso foliaceo; foliis alternis petiolatis oblongo-oblan-

ceolatis 7-14 cm. longis 2.5-4 cm. latis acutis supra livido-viridibus

glabris subtus dense albo-tomentosis, marginibus integerrimis revolu-

tisque, basi in petiolam sensim gradatim angustatis; petiolis usque ad

2 cm. longis; inflorescentiis terminalibus cymosis archnoideo-tomen-

A well-marked and easily recognized species on account of the

trifurcate branching of stem, the narrowly lanceolate discolorous

leaves, and the close inflorescence of cylindrical glabrous discoid heads.

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 of 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 under 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.

II.— DIAGNOSES OF NEW SPECIES AND NOTES ON

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.

lvii. 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.

330 Field Museum of Natural History — Botany, Vol. II

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 (hb. 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.

Celosia Orcuttii Greenman, sp. nov.

Suffruticosa (?); caule striato-anguloso ferruginoso glabro; foliis

brevipetiolatis lanceolatis acutis vel mucronatis integerrimis basi

attenuatis utrinque glabris flavo-viridibus ; inflorescentiis pyramido-

paniculatis usque ad 4 dm. longis 2.5 dm. latis inconspicue ferrugineo-

puberulentis vel hirtellis; floribus sessilibus; bracteis trangulare-ovatis

et persistentibus ; cupulo staminorum circiter 1 mm. alto; utriculo ma-

ture incluso subgloboso circumscisse dehiscens; seminibus lenticularibus

nitidulis 1-1.5 mm- diametro. — Mexico. State of Colima: vicinity of

Colima, 24 October, 1910, C. R. Orcutt, no. 4587 (hb. Field Museum cat.

no. 283404).

A species similar to C. Moqiiini 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.

Pfaffia Hookeriana (Hemsl.) Greenman, comb. nov. Hebenanthe

Hookeriana Hemsl. Biol. Cent. -Am. Bot. iii. 19 (1882).

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, and 1810 (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.

and puberulent pods. D. Conzattii suggests D. amplifolium Hemsl.,

but that species again has longer petioles, larger leaflets, and stipules

of quite different outline.

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.

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.

known Halesia elongata Don, but that species is said to have linear-

lanceolate leaves.

procedente de Almoloyas, altitude 800 m., 15 August, 1907, C. Con-

by the venacular name of " Jicama del Monte."

Ipomcea dasysperma Jacq. Eclog. i. 132, /. 8g (1811-1816).

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 18 14; 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.

(24 May, 1909).

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

which a part of the material above cited has been hitherto confused.

The more striking characters distinguishing L. albicaulis from L. iimbel-

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. ccerulea Moc. &

Sesse and 5". 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 6". 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

Bourgceii 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.

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.

PlCRIS ECHIOIDES L. Sp. PI. 792 (1753).

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.
