places in the alpine regions of the mountains. Battle Lake Mountain, Anirnst 

 17 (4042). 

 Carex nova Bailey (The New Sedge).— Erect and slender, stemmed with short Hat 

 leaves; 15 to 25 inches high; somewhat scattering, in the wet spruce woods ;ind 

 along the creeks in the mountains. Probably of value as pasture. Battle Lake, 

 August 16 (4007). 

 Carex preslii Steud. (Presl's Sedge).— A. tufted alpine form with numerous soft, 

 slender leaves that are greatly relished by grazing animals; 8 to 10 inches high. 

 Battle Lake Mountain, August 17 ^4053). 

 Carex pyreuaica Wahl.— A very suiall, tufted form, only a few inches high, strictly 

 alpiue, observed only about the permanent snowdrifts on the mountains. Baltic 

 Lake Mountain, August 17 (4058). 

 Carex raynoldsii Dewey (Raynolds' Sedge).— Erect but weak stemmed, leaves 

 broad and Ihit; the short cylindrical heads usually two, a foot or more high; 

 rare and very scattering. Battle Lake, August 16 (4020). 

 Carex scirpoidea Michx. (Rush-like Sedge).— Erect with an abundance of short 

 root leaves, only 6 to 10 iuches high. It develops early on wet ground on bottom 

 lauds and so furnishes a perceptible part of the spring pasture. Pine Blufls, May 

 15 (2901); Laramie, May 31 (2943), 

 Carex siccata Dewey (Hillside Sedge).— From strong, tufted root-stocks, slender 

 stems and numerous leaves as long as the stems. This is a dry-ground sedge, 

 being abundant on fertile hillsides, where it develops early and gives much 

 valuable pasture. Evanston, May 29 (3001); also frequently collected in the 

 Laramie Hills. 

 Carex stenophylla Wahl. (Dwarf Sedge).— This is the earliest on the Laramie 

 plains, but in many places it also maintains itself till late in the season. It 

 often forms a fairly uniform growth, but its small size (4 to 6 inches in htight) 

 and slenderuess make it seem rather insignificant. As spring pasture on the 

 plains, it has value. Colorado-Wyomiug line, Sweetwater County, July 23 

 (3803); Grand Encampment Creek, August 13 (3991). 

 Carex tenella Schk. (Soft-leafed Sedge).— A very delicate, slender-stemmed and 

 soft-leafed plant, a foot or less high, usually in damp, shaded places; never 

 observed in sufficient abundance to have any economic signiticance. Woods 

 Creek, August 9 (.3941). 

 Carex tolmiei Boott.— A stout, mountain form with long, broad leaves, a foot or so 

 high, usually as strongly root-tufted bunches. Not abundant enough to have 

 much signiticance but evidently relished by grazing animals. Battle Lake, 

 August 16 (4005 and 4072). 

 Carex trichocarpa aristata Bailey (Awned Sedge),— One of the largest of the 

 sedges, stems thick and producing a succession of heads, the leaves broad, flat, 

 and often overtopping the stems, the whole producing a very dense growth 3 to 

 4 feet high. It prefers very wet ground, but produces abntidantly on ground 

 that dries out in late summer. I have seen considerable areas yielding an 

 immense amount of forage harvested with the usual niadiinery. Laramie, Sep- 

 tember 15 (4469). 

 Carex trichocarpa imberbis Gray (?).— This is much smaller than the pre«ediug 

 with longer, denser heads; somewhat tufted and usually growing in the margins 

 of creeks or ponds; not plentiful. North Vermilion Creek, .July 20 (3S02). 

 Carex utriculata minor Boott. (Small Bottle Sedge).- A rank-growing sedge 

 of the wettest ground, with thick stems and Jong, broad leaves, often 2 or 3 feet 

 in lieight; heads usually three to four on each culm. It is very abundant and 

 wididy distriinited; on grounds that become sufficiently dry to admit of it, it is 

 cut and is said to Ibrm fair hay. Head of North Vermilion Creek, July 20 

 (3801); Evanston, July 28 (3861); Johnson's Ranch, Big Laramie, Augusts 

 (3><96) ; Battle Lake, August 16 (4036),
