Differs frem the following species in its fruit, pubescence, and stouter, coarser aspect.

131 C. Hitchcockiana Dew. (Boott. t. 94.) Spike erect, pedunculate; Spikes 2 - 3, erect, 5 to 10-flowered, lowest distant; perig. oval-triquetrous, tapering at both ends, inflated, alternate, bent at the apex, striate, with a short, truncated and open beak, about equaling or shorter than the oblong or ovate, mucronate glume; st. 10 - 24' high, erect, stiff, scabrous above, with long and leafy braets; st. lvs. and bracts scabrous and subpubescent. - Borders of woods, N. Eng. to Ill. and Ky.

132 C. styloflexa Buckley. Spikes cylindric, short, slender, erect, with oblong, obtuse glumes; spikes 1 to 4, oblong, dense, some of them near the staminate and subsessile, the others distant or very remote, on long (2 to 6'), filiform, exsert, drooping peduncles, leafy-bracted; perig. ellipsoid, tapering below, rostrate, often recurved, once to twice longer than the ovate or lance-linear, membranous glume; culm 2f, slender, flaccid, triquetrous, longer than the smooth, light green leaves. - Mts. X. Car. (Buckley) and Va. to Fla. (C. laxiflora, β. styloflexa, Boott. t. 87).

133 C. debilis Michx. Spike erect, filiform; spikes 3 - 4, not very rarely pistillate above, filiform, hose-flowered, flexuous, nodding, remotish, 1 - 2' long; perig. oblong-lanceolate, subtriquetrous, alternate, rostrate, bifid, glabrous, nerved, nearly twice longer than the ovate-lanceolate glume; st. 1 - 2f triquetrous and scabrous above, leafy towards the base. - Bright green. Moist woods and meadows, common. (C. flexuosa Schk.)

134 C. arctata Boott. Spikes 3 - 4, long and slender, loose-flowered, nodding and remote; perig. ovate, triquetrous; lanceolate or long-rostrate, subventricous, bifid, glabrous, little surpassing the ovate, membranaceous, mucronate glume; st. 10 - 20', scabrous above and leafy below. - Pale green. In the same situations as the preceding, common. (C. Sylvatica Dew. Sill. Jour.)

135 C. Sullivantii Boott. (t. 122). Spikes 3, oblong, erect, cylindric, rather loose-flowered, bracted, the lowest long-pedunculate and sparse-flowered below; perig. ovate or oval, apiculate, scarcely veined, scabrous-hairy, short-pediceled; glume on the lowest spike obovate, obtuse or emarginate, long-cuspidate, the cusp extending above the fruit; on the upper spike the cusp is shortened and the oblong glume scarce equals the fruit; culm 1 to 2f, longer than the leaves plant slightly hairy, light green. - Columbus, Ohio (Sullivant).

136 C. Kneiskernii Dow. Spikes 3, long-cylindric. rather distant, sublax-flowered, with recurved peduncles; perig. ovate, oblong, subtriquetrous, glabrous, terete-conic, rostrate, short-2-toothed, a little longer than the ovate and oblong glume which is obtusish and short-mucronate. - Woods, Oriskany and Rome, N. Y. Closely related to C. Sullivantii, but differs materially when mature, in the fruit, glume and long triquetrous achenium. Also, by the same marks, from C. arctata Boott. to which Carey improperly (as mentioned by Boott. t, 122) re-fers it.

137 C. capillaris L.
