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, compressedtrigonous or almost flattened in cross-section, base rounded, apex beaked, smooth or papillose, glabrous; beak 0.3–0.5 mm, entire, emarginate, or bidentate.
