80 PROCEEDINGS OF THE AMERICAN ACADEMY. 
two-thirds as broad, submucronate, essentially glabrous on both surfaces, 
or distinctly appressed-puberulent beneath: inflorescence paniculate or 
terminating the lateral branches in few-flowered corymbose clusters: 
flowers large, 5 cm. in diameter when fully expanded: sepals glabrous, 
strongly unequal, the larger about 1 cm. long, ovate-subrotund or slightly 
oblong, the smaller ovate-oblong, about 5 mm. in length, somewhat boat- 
shaped: petals yellow, obovate-oblong to distinctly oblong, 2.5 cm. long, 
1.5 cm. broad, abruptly narrowed at the base into a 3 mm. long claw, 
3-nerved from the base: stamens unequal : ovary glabrous, many-ovuled: 
legumes 2 dm. long, about 8 mm. wide, reticulate-veined, glabrous, 
somewhat granulose or dotted with minute blisters. — Mexico. State 
of Morelos: near Jojutla, altitude 3000 feet, 12 May, 1901, C. G. 
Pringle, no. 9642 (hb. Gr.). 
The affinity of the species here proposed is clearly with C. Galeottiana, 
Mart. & Gal., from which, however, it is distinguished by the armed 
character of the lateral branches, the smaller, nearly or quite glabrous 
leaflets, the appressed nature of the pubescence, and finally by the elon- 
gate-linear not oblong legume. 
Desmodium Seatoni. D. subsessile, Seaton, Proc. Am. Acad. 
xxviii. 118 (1893), not Schlecht., in Linnza, xii. 319. 
Desmodium xylopodium. Stems several from a suffruticose base, 
ascending or suberect, 3 to 6 dm. in length: leaves unifoliolate ; petioles 
4 to 8 mm. long, and as well as the stem uncinulate-hispidulous; stip- 
ules obliquely ovate, acute, strongly nerved, caducous ; the single terminal 
leaflet ovate to oblong, 8 to 27 mm. long, 5 to 15 mm. broad, rounded 
or retuse and often mucronate-apiculate at the apex, entire, slightly 
revolute-margined, rounded or subcordate at the base, nearly or quite 
glabrous above, prominently veined and slightly puberulent beneath ; 
‘stipels subulate, persistent; petiolules scarcely more than 1 mm. in 
length: inflorescence racemose or paniculate, terminating the stem; 
pedicels slender, usually in pairs, 6 to 8 mm. long; bracts caducous: 
flowers small, about 5 mm. long, purple: legumes at first minutely pu 
berulent, later becoming glabrous, 1-2-jointed; joints suborbicular or . 
slightly oblong, 3 to 4 mm. long, nearly or quite as broad, rather strongly 
reticulate-veined. — Mexico. State of Jalisco: near Guadalajara, alti- 
tude 1500 m., 13 May, 1901, C. G. Pringle, no. 9657 (hb. Gr.). 
The affinity of this species seems to be with Desmodium guadala- 
jaranum, Watson, from: which it is readily distinguished by the smaller 
leaflets, and by the absence of spreading or subvillous hairs on the 
leaf-surface.
