(2627.) C. Salterensis, Bailey, Mem. Torr. Bot, Club, I., 7.

C. vaginata, Tausch.; Macoun, Cat. IV., 153.

Professor Bailey separates this species from the European C. vaginata by its much more slender and less caespitose habit, narrower leaves and less conspicuous sheaths, its alternately-flowered spikes, and its much smaller, less inflated, and conspicuously nerved perigynium. All references in Part IV., 153, belong here. Low ground near Hamilton, Out., 1889. (Burgess.)

(2636.) C. laxiflora, Lam.; Macoun, Cat. IV., 155.

Professor Bailey has revised this species and finds the type to be what we have been calling C. laxiflora, var. intermedia, Boott. It embraces slender plants, characterized by narrow leaves (usually less than \ in. in width), a pedunclcd, or at least very conspicuous staminate spike, scattered pistillate spikes, which are very loose flowered and narrow (1/2 to 1 1/2 in. long), and very blunt perigynium. This includes both the type and var. intermedia of Part IV"., 155. The synonymy may be considered cancelled, as it only refers in part to the type.

Not uncommon in woods and open thickets between Yale and the coast of British Columbia, 1889. (Macoun.)

(2639.) C. digitalis, Willd., var. copulata, Bailey, Mem. Torr. Bot. Club, I., 47.

C. retrocurva, Macoun, Cat. IV., 156, in part. "Larger than in the species, the culm weak and reclining, sometimes two feet long; leaves twice or thrice broader; spikes shorter and heavier; perigynium mostly larger. In aspect much like C. laxiculmis, but has no glaucousness, the upper spikes are shorter peduncled." (Bailey.) Wet ravines, London, Ont., June 24th, 1881. (Burgess.)

(2647.) C. Pennsylvanica, Lam., var. vespertina, Bailey, Mem. Torr. Bot. Club., I., 47.

C. Pennsylvanica, Macoun, Cat IV., 158, in part. "Habitually taller than the species, very slender; staminate spike commonly slimmer and usually very short-peduncled; pistillate spikes more separated and the lowest subtended by a leafy bract from one half inch to one inch long; perigynium mostly larger, more hairy, the beak longer and stouter." This form includes all our British Columbia and Vancouver Island specimens of C. Pennsylvanica.

C. Novae-Angliae, Macoun, Cat. IV., 160, in part.

"Very slender, stoloniferous, the culms 6 to 8 inches high, about the length of the very narrow loose leaves; staminate spike quite distinct, erect and prominent, 3 to 8 lines long, mostly minutely peduncled, exceedingly narrow (about half a line broad); pistillate spikes usually two, the upper near the base of the staminate spike, the lower from 1/2 to 1 inch removed and short-stalked and subtended by a bract which nearly or quite equals the culm, both rather loosely three to six-flowered; radical spikes none; perigynium very narrow, often nearly oblanceolate, very thinly hairy, the sharp beak prominent; stigmas often two."
