Var. Oregana, Bailey, Mem. Torr. Bot. Club, I., 75.
C. arcta, Boott; Macoun, Part IV., 125, in part.
"Head larger and more dense than in the var. polystachya, becoming brown; spikes loosely flowered, the perigynia sometimes spreading in a stellate manner; perigynium narrow, often almost linear-lanceolate, brown-nerved, sharp edged and rough above." Very abundant in ditches at Hastings, B.C.; and Victoria and Nanaimo, Vancouver Island. (Macoun.) Cedar Hill, near Victoria, V. I. (Fletcher.) Vancouver City, Burrard Inlet, B.C. (Prof. Fowler.)
A very tall form growing in clumps in boggy places. Spikes 6 to 8, generally 7, often half an inch long, tapering at the base, lower spikes distant and peduncled, the latter four forming an oval head, lower with a short setaceous bract, whole head with a light silvery hue. In damp woods at Port Haney, B.C., May 1st, 1889. (Macoun.) Burnaby Lake, near Hastings, B.C., April, 1889. (J. M. Macoun,)
Low and slender, scarcely a foot high, growing in tufts in ditches. Spikes brown, scattered, 3 to 5, generally 4, small, but elongated, the upper often half staminate; lower bract seldom longer than the spike. The scattered light-brown, elongated, spikes distinguish this variety from all other forms of the species. Port Haney and Port Moody, B.C., May 3rd, 1889. (Macoun.)

Fine specimens were collected at Lytton and Spence's Bridge on the Thompson River, B.C., May, 1889. (Macoun.)
(2566.) C. pratensis, Drej., var. furva, Bailey, MS. C. pratensis, Macoun, Cat. IV., 128,
in part. "Spikes much larger than in the type (1/2 in. or more long), more loosely flowered, dark brown. The culms appear to be more sharply angled, also." (Bailey.') Not uncommon in damp meadows at Cedar Hill, Coldstream, and throughout southern Vancouver Island, May 27th and 31st, 1887. (Macoun.)
(1809.) C. adusta, Macoun, Cat. IV., 129, in part. "Culm slender and often weak (1 to 2 feet high); head long and weak; spikes five to eight, small and silvery green, much contracted below and alternately disposed; perigynium varying from ovate to long-ovate, thin, much longer than the small achenium, prominently rough-margined, strongly many-nerved on both sides; bracts entirely wanting or very inconspicuous." In the valley of Eagle River at Griffin Lake, B.C., July 7th, 1889. (Macoun.)
Var. perplexa, Bailey; Mem. Torr. Bot. Club, I., 27. C. adusta, Macoun, Cat. IV., 129, in part.
"Mostly taller and stouter than the species, the spikes larger and less attenuated or even truncate below, more approximate or even aggregated, the head erect or nearly so and the lowest bract sometimes prominent." Burnt woods, North Hastings, Ont., and near the Lake of the Woods. (Macoun.)

Var. cumulata, Bailey, Mem. Torr. Bot. Club, I., 23. C. straminea, var. alata, Macoun, Cat. IV., 133.
"Culm very tall and stiff; spikes several to many (sometimes 25!), greenish, usually aggregated into a bunchy head, very densely flowered and squarely contracted at the base, short and pointed, spreading; peri-gynium appressed, the points therefore not conspicuous."

Prof. Bailey says that the synonym G. petasata, Dew., should not have been placed here in Part IV. All our own specimens go here. Summit of Mount Queest, Gold Range, B.C. Alt. 6000 feet, 1889. (J. M. Macoun.) Gold Range, north of Griffin Lake, B.C. Alt. 6500 ft. 1889. (Macoun.)
(2574.) C. bicolor, Allioni; Macoun, Cat. IV., 134.
Of a specimen received from Mr. J. Brittain, Fredericton, New Brunswick, which we doubtfully referred here, Professor Bailey writes: "It has many of the characteristics of G. bicolor, but I should prefer to call it G. aurea until more material accumulates." It is retained here until New Brunswick collectors get more material. Upper Resti-gouche River, N.B., July, 1883. (Brittain.)
(2578.) C. atrata, Linn., var. ovata, Boott; Macoun, Cat. IV., 135.
"Habitually more slender than the species and usually lower, spikes small or oblong-ovate, reddish-brown, slenderly peduncled," This form includes all our herbarium specimens collected between the Atlantic Coast and the Rocky Mountains. Mountain specimens are placed under G. atrata, as they are identical with Greenland specimens, having the heads short peduncled and closely aggregated, while the scales are deep black without any tinge of red. The specimens referred to G. atrata, var. nigra, in Part IV., arc placed with the species, and the variety disappears, as Prof. Bailey erects Olney's variety into a species named C. nova. All our specimens are more or less peduncled, and hence are excluded.
