from Coultcr's Mcxican collectioii, which exhibits the fmit. The coroUa is twice 

 the size of that of E. Wri^jhtii. The leaves are one to two inches in diameter 

 Sicyos cremocarpns, Schauer in Linncea, 20. j9. 722, is probably a congener of this, 

 and possibly the same species ; but it is said to have the lobes of the leaves entire 

 or ncarly so, the tendrils simple, and the fruit glabrous. The surface of the fruit 

 and the prickles in ours are sparsely hirsute.

 Stony hills, near thc coppcr mines, New Mexico, Aug. ; and in a rocky ca 

 wards the Guadalupe Pass, Oct. (1091.) — This is the same as No. 50 of Coulter's 

 Mexican collection, from Eeal del Monte. The branches and the leaves are usually 



scabrous-pubescent ; and the ripe fruit, which is only three lines long, is ovoid, 



obtuse, and not crowned with the remains of the calyx. The retrorsely barbed 



prickles are at length partly deciduous from 



pericarp, which is closely 



conformed to the oval secd. The leaves are rugosely veined, rounded in outline.

SicYosPERMA GRAciLE. — Mountaiu raviue at Santa Cruz, Sonora ; Sept. (1092.) 



Stems 2 to 5 feet long, slender, glabrous, or slightly scabrous-hispid, like the 

 petioles. Leaves from three fourths of an inch to three inches in diameter, some- 

 what pubescent and scabrous, denticulated, angled or obscurely 5-Iobcd, the termi- 

 nal lobe conspicuously mucronate. Tendrils mostly 2-cleft. Sterile racemes shorter 

 than the pctiole; those of the proliferous branches of the inflorescence shorter than 

 the 3-parted and crenate-toothed bract, which subtends and loosely incloses the ac- 

 companying fertile flower. CoroIIa barely a line or a line and a half in diameter ; 

 the lobes ovate ; those of the sterile flowers tipped with two conspicuous cuspidate 

 points ; which are wanting in the fertile flowers. Ovary at first pubescent with 

 sparse and lax hairs, containing a single ovule suspended from the summit of the 

 cell. Fruit 2 lines long, ovate-Ienticular, smooth, green, turning brown or blackish 

 when fully maturc, and appcaring likc a seed : the thin and membranaccous pe- 

 ncarp closely investing the turgid-lenticular and smooth seed. — The character
