Q2 PLANTS WRIGHTIAN^. VI. 



from Coulter's Mexican collection, which exhibits the fruit. The corolla is twice 

 the size of that of E. Wrightii. The leaves are one to two inches in diameter. — 

 Sicyos eremocarpus, Schaucr in Limuea, 20. p. 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 nearly so, the tendrils simple, and the fruit glabrous. The surface of the fruit 

 and the prickles in ours are sparsely hirsute.

 Stony hills, near the copper mines, New Mexico, Aug. ; and in a rocky canon to- 

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

 Mexican collection, from Real 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 the mature pericarp, which is closely 

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

 and very unlike those of S. angulatus. Instead of the rank smell of that species, 

 the foliage, in cultivated specimens, exhales a rather pleasant odor in drying.

SicYosPERMA GRACiLE. — Mouutaiu raviuc at Santa Cruz, Souora ; 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-lobed, the tei'mi- 

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

 than the petiole ; 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. Corolla 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-lenticular, smooth, green, turning brown or blackish 

 when fully mature, and appearing like a seed : the thin and membranaceous pe- 

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