BOT.-VOL. II.] PARISH— WESTERN AMERICAN SOLANUMS. l6l 



An original Douglasian specimen represents S. genis- 

 toides. The stems are slender; the leaves few, somewhat 

 fascicled, minute (5-6 mm.), and ovate; the hairs on the 

 peduncles are mostly branched, on other parts of the plant 

 they are entire, or a few once-branched. As in the first 

 species, all are one-celled and glandless. The specimen has 

 the appearance of coming from a starved plant, as Dr. Gray 

 suggests. Coulter's No. 590, also from Trinity College 

 Herbarium, is a like form. 



A specimen of the plant of Douglas, on which S. cali- 

 fornicum was based, has stout stems canescently tomentose, 

 with hairs all of which are branched. The leaves are broadly 

 ovate (2-4 cm.), cuneate at base, and sparsely hirsute with 

 mingled unbranched and few-branched hairs. The struc- 

 ture of all the hairs is as in the other species. A specimen 

 by Fremont, mounted on the same sheet, is a better repre- 

 sentative of this form, and has like characters. 



The plant collected by Xantus de Vesey, No. 73, at or 

 near Fort Tejon, California, may be taken as the type of 

 the species which bears his name. It has oblong leaves 

 (circ. 3 cm.) mostly acute at summit and cuneate at base, 

 except a few leaves lobed and truncate at base. The whole 

 plant is moderately hirsute with rather short plurilocular 

 hairs. Anderson's, Lemmon's, and Bigelow's plants are on 

 the same sheet. The first is quite like that of Xantus ; the 

 other two are mere fragments with similar pubescence and 

 oblong leaves, which are obtuse or subcordate at base, and 

 probably were taken from plants whose lower leaves were 

 cordate. Wallace's Santa Catalina Island specimen (type 

 of the variety wrt//«c^/) is likewise fragmentary. It consists 

 of the summit of a branch with an ovate leaf (9 cm.) and a 

 few young leaves, and an umbel of flowers with large corollas 

 (4 cm.); the pubescence of the stem is of long tawny 

 hairs, multilocular and viscid-glandular; the leaf is nearly 

 glabrous above and tawny- villous below. All the hairs 

 appear to be unbranched, but other specimens commonly 

 show some few-branched hairs.
