80 PROCEEDINGS OF THE AMERICAN ACADEMY. 



two-thirds as broad, subrnucronate, 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 ram. long claw, 

 8-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 (lib. 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 Linnaea, 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 unciuulate-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.
