Geraniums. var.? 5. Geranium acuta, Mix. ? referred by Hooker & G. Amatulle, L. big (inferred) with specimens from Australia & Afghanistan, probably rightly; — This form is the same as G. darvishiana, of Nuttall's Mnt., from the head waters of the Snake, which has been included in G. Tennis's Griseb. It is very doubtful whether the two species are distinct, as the differences are but slight and inconsistent. — The present specimens are tall (1'6-2'), much branched or nearly simple, leaves linear-lanceolate, (1-1½' long) Distinct or sometimes crowded at base; flowers small and rather crowded; calyx 5-cleft, with unequal lobes, about equally the entire tube, sebrous margin; corolla 5-lobed, obtuse or rounded, head full, and glabrous at the base very indistinctive. a) Aug. 20, 1867. Humboldt Valley — Creek bank 6,000 ft. 1 sp. b) Sept. 1 " Ruby Valley — W. side of Franklin Lake 5. c) Sept. 20 " Humboldt Valley — near Pano 1. 6. G. acuta, Mix. — mostly with anthracoid specimens. A mountain form, 2-10' high, leaves broader than the last but one cation margin (as well as the calyx.) flowers racemose in axils, less numerous & crowded; calyx slept nearly to base, corolla with five lobes & no glands, less more or less acuta. Calyx lobes sometimes in a pair, sometimes very acute. a) Aug. 29, 1867. E. Humboldt Mts. — Mountain side above lake 9,500 ft. 1 sp. b) July 31, 1869. Winchell Mts., Bear River canyon — bottom 8,000 " 7 sp. 7. G. [illegible] Engle — but scarcely more than a variety of the last. 4-16' high, subumbellate, stem & branchlets strongly angled. glands obscure. Range of acuta & Tennis’s. From the mouth of the St. Lawrence westward to the Pacific, and north to the Great Lakes and Mackenzie River; Rocky Mts. Colorado & in the Sierra of California. a) July 14, 1869. Wasatch Mts., Cottonwood Canyon — below lake 8,000 ft. 1 sp. b) Aug. 11, " Winchell Mts., Bear River Canyon — [illegible] 5,000 " 2. Also by H. G. Smith, in Winchell Mts., north slope (near Mt.
