purple, its lobes ovate and acute : ovary glabrous but granulate. Proc. Am. Acad. 

 vii. 350. 



Sierra Nevada (on the Mono trail, Bolandcr ; Sierra Valley, Lemmori). Apparently of the 

 same species is a plant in Rattan's collection, with similar (sterile ?) flowers, but branches and 

 foliage minutely hirsute. Plants apparently one or two feet high : base of stem not seen. Leaves 

 3 to 6 lines long. Corolla a line and a half broad. 



9. Gr. pubens, Gray, 1. c. Cinereous-pubescent throughout with short and 

 rather soft spreading hairs, diffusely much branched : leaves in fours, thickish, 

 ovate, or on the branchlets oblong or even oblong-linear, acute or mucronate- 

 pointed : flowers polygamo-dioecious, the sterile in several-flowered close cymes, the 

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

 acute : fruit minutely pubescent, becoming glabrous and smooth. 



Var. scabridum, with shorter, less copious, and rather scabrous pubescence : 

 ovary glabrous. 



Yosemite Valley (Bolander, 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. 



-*- -t- With erect and wholly herbaceous smooth stems : fruit smooth or merely pubes- 

 cent : leaves 3 5-nerved. 



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

 leaves in fours, lanceolate or almost linear, bluntish : cymes many-flowered, in a 

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



Shaded or open banks of streams, towards Oregon ; thence northward and eastward to the At- 

 lantic. (The plant of Xantus from Fort Tejon, No. 40, belongs to the next species.) 



+- -j- -t- With erect or ascending stems more or less woody, and polygamo-dioecious 

 (yellowish-white) flowers : sterile ovaries glabrous or naked : the fruit clothed with 

 long white hairs, ivhich are not hooked at the tip. 



11. Gr. angustifolium, Nutt. Shrubby at base, 1 to 4 feet high, glabrous : the 

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

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

 merous in a narrow panicle : flowers very small, greenish-white : fruit hispid or 

 hirsute, with straight bristles not longer than itself. G. trichocarpum & angustifo- 

 lium (under trichocarpum), Nutt. in Torr. & Gray, Fl. ii. 22. 



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

 when supported on bushes. Leaves from 3 to 8 lines long. The male plant, which has smooth 

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

 dary, and for G. boreale in the Tejon collection by Xantus. The female plant does not accord 

 with any Chilian species, neither with the G. eriocarpum of Bartling (whether that be Hooker 

 and Arnott's species of that name, or G. Gilliesii), nor with G. trichocarpum, DC., which by 

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

 the forms may be adopted for this species. 



12. Gr. Bloomeri, Gray. Low, 3 to 12 inches high, wholly smooth and gla- 

 brous, much branched from the suffrutescent base : leaves in fours, 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-pedicelled ; 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 spreading hairs : leaves 

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



Sierra Nevada, on the dry eastern slopes, towards Virginia City and to Lassen Peak, &c. 

 Hairs of the fruit a line or rather more in length. In this and the next the substerile or imper- 

 fectly fertile ovary is apt to develop a few long hairs ; but the truly fertile fruit is mostly cov- 

 ered with long hairs. The variety, from Sierra Valley, Lemmon, 



13. Gr. multiflorum, Kellogg. Low, 3 to 12 inches high, cinereous-puberulent 

 or minutely scabrous, branched from the suffrutescent base : leaves in fours, or some
