Plants cespitose or not, short-rhizomatous. Culms red, purple, or brown at base. Leaves: basal sheaths fibrous; sheath fronts membranous; blades V-shaped in cross section when young, smooth or papillose. Inflorescences racemose with 2–5(–9) spikes; proximal bracts leaflike or filiform, sheathless; lateral spikes pistillate or, rarely, androgynous in C. microchaeta, pedunculate, prophyllate; terminal spike staminate. Proximal pistillate scales black or dark brown, not leaflike, less than 5 mm, apex acuminate or shortly awned. Perigynia erect or ascending, veinless or weakly veined on faces, with 2, strong, marginal veins, sessile, ovate, obovate, or nearly circular, compressed-trigonous or almost flattened in cross section, base rounded, apex beaked, smooth or papillose, glabrous; beak 0.3–0.5 mm, entire, emarginate, or bidentate.
