 rather soft spreading hairs, diffusely much branched : leaves in fours thi.'kish

 pointed : flowers polygamo-dioecious, the sterile in several-flowered close cvme. tlie 

 fertile fewer : peduncles and pedicels short : corolla dull purple, its lobes ovate and 

 acute : Iruit minutely pubescent, becoming glabrous and smooth.

Yoseniite Valley {Bolandcr, Torrey, Gray). Stems about 2 feet long. Leaves 4 lines long 

 Corolla 2 lines broad, sometimes 3 - 5-cleft. Fruiting pedicels little over a line in length ^'

10. Gr. boreale, Linn. Glabrous and smooth, or nearly so, strictly erect, leafy • 

 leaves in loui-.s, lanceolate or almost linear, bluntish : cymes many-flowered in a 

 thyrsiform panicle : corolla white : fruit very minutely hairy or smooth.

11. G. angustifolium, ^^utt. Shrubby at base, 1 to 4 feet high, glabrous : the 

 branches rigid or strict, smooth on the angles : leaves in fours, linear, nnicronate- 

 acute, rigid, 1-nerved, veinless, with barely scabrous margins : cymes small and nu-

Near the coast, Santa Barbara to San Diego, and east to Fort Tejon. Rising to 3 or 4 feet lii-h 

 when supported on bushes. Leaves from 3 to 8 lines long. The male plant, which ha.s 8nioo"tli 

 and glabrous abortive ovaries, was taken for G. suffruticosum in the Botanv of the Mexican Boun- 

 dary, and for e. boreale in the Tejon collection by Xantus. The femah- plant does not a.roni 

 with any Chilian species, neither with the G. criocarpum of Bartling (whether that W H.K>kor 

 and Arnotts species of that name, or G. GilUcsii), nor with G. tridu.canntm, DC which bv 

 the character answers to G. Chamissonis, Hook, k Arn. Wherefore Nuttall's name for one of 

 the iorms may be adopted for this species. 



12. G. Bloomeri, Gray. Low, 3 to 12 inches high, wIk.IIv smooth and gla- 

 brous, much branched from the suflruteseent base : leaves in fouK:, and some of the 

 uppermost only in pairs, ovate, cuspidate-acuminate, rigid, 1 - 3-nerved : flowers 

 yellowish-white, somewhat panicled ; the sterile ones very short-pedicellod ; the fer- 

 tile mostly longer than the long villous hairs of the fruit, and erect. — Proc. Am. 

 Acad. vi. 538 ; Watson, Bot. King. 135. 



Var. hirsutum, Gray. Stems and leaves hirsute with sjtroading hairs : leaves 

 thinner : otherwise like a small form of G. Bloomeri. 



Sierra Nevada, on the dry eastern sloj)es, towards Vir£;iuia City and to Lassen Peak. &c. 

 Hairs of the fruit a line or rather more in length. In this and the ne.vt the substerile or ini|»er- 

 feetly fertile ovary is apt to develop a few long liairs ; but the trulv fertile fruit is mostly cov- 

 ered with long liiiirs. — Tlie variety, from SieiTa Valley, Lcmmon.
