C. vulgaris, Macoun, Cat. IV, 142, in part.

"Tall and lax (1 1/2 to 2 1/2 ft. high), the leaves long and narrow; staminate spike longer peduncled; pistillate spikes looser and often longer than in the species, the perigynia never being so densely packed and usually becoming browner." Lower St. Lawrence. (Pringle, fide Bailey.) North-west Arm Ferry and Point Pleasant, Halifax, N.S.; also at the mouth of Madalene River, Gaspé Coast, Q. (Macoun.)

(2599.) C. decidua, Boott; Macoun, Cat. IV., 143.

The specimens from Rogers Pass, Selkirk Mountains, belong here. It turns out to be a common species in British Columbia, and seems as much at home at 1100 feet altitude as at 6000. Mount Queest, Gold Range, B.C. (J .M. Macoun.) On the Gold Range north of Griffin Lake, alt. 6000 feet; shore of Shuswap Lake, and along the Thompson to Kamloops, quite common. (Macoun.) Professor Bailey writes that the present arrangement of specimens under this species is provisional. It is the Pacific representative of G. vulgaris.

(2600.) C. invisa, Bailey; Macoun, Cat. IV., 143.

Common along Queest Creek, Shuswap Lake, B.C. Alt. 5000 feet. (J. M. Macoun.) Mountains north of Griffin Lake, Gold Range, B.C. Alt. 6000; also along Spallumsheen Arm, at Sicamous, B.C. 1200 feet alt. 1889. (Macoun.)

(3195.) C. variabilis, Bailey, Mem. Torr. Bot. Club, I., 18.

C. aquatilis, Macoun, Cat. IV., 143, in part.

"Glaucous; mostly low (2 feet or less high), stout, culm sharply angled, roughish on the angles; leaves rather broad (as compared with G. stricta, Lam.); spikes three or four, short and stout (2 in., or less, long), borne near the top of the culm, erect, the lower one or two conspicuously attenuated at the base, and appearing clavate, the upper sessile, lower peduncled; bracts leaf-like and broad, the lower one or two equalling or exceeding the culm; perigynium small and broadly ovate, abruptly and very short beaked, nerveless, beak entire, green or whitish, conspicuously broader and usually shorter than the obtuse or muticous black scale." Old Wives' Lakes, Assiniboia; along Bow River at Calgary, Alberta. (Macoun.)

Var. elatior, Bailey, l.c.

"Much taller, the leaves very long, and narrower; spikes longer (often 3 to 4 in.) and more slender, the lower much attenuated below, the upper bearing conspicuous staminate portions; bracts long and narrow." Open thickets at Morley, foot-hills of Rocky Mountains; Kicking Horse Lake, Rocky Mountains, and Donald, in the Columbia Valley; near Cedar Hill, Victoria, Vancouver Island. (Macoun.)

(3196.) C. aperta, Boott; Hook., PL, II., 218, 219.

Fifty miles up the North Thompson River, above Kamloops, B.C. 1889. (J. M. Macoun.) By a lake near Fort St. James, northern British Columbia, June, 1875; abundant at Shuswap Lake and Agassiz, B.C. 1889. (Macoun.)

(2605.) C. acutina, Bailey, Mem. Torr. Bot. Club, I., 52.

C. acuta, Linn.; Macoun, Cat. IV., 146.

"A fine suite of specimens of Carex acuta given me by Arthur Bennett, Croydon, England, and a study of the species in various foreign herbaria, have enabled me to draw lines of separation between the European plant and the western plants which have been referred to it. O. acutina differs from G. acuta in the pale color of the plant and its lesser size and thin leaves, habitually smaller spikes, thinner and shorter perigynium, which is much less prominently nerved, and the lighter colored obtuse or muticous scales." (Bailey.) Lewes River, Lat. 62°, N.W.T, 1887. (Dawson.)

Gordon Head, Nanaimo, Qualicum and Comox, Vancouver Island; common in salt marshes along Burrard Inlet, B.C. 1889. (Macoun.)
