Description Plants loosely cespitose. Rhizomes horizontal, slender, 1–3 mm thick. Culms (5–)10–45 cm × 1–2(–3) mm, glabrous. Leaves 1–3; ligules 0.3 mm; blades distichous, thickly crescentiform in cross section, 2–12(–18) cm × 1.5–4 mm, conspicuous midrib absent, apex blunt, glabrous. Inflorescences in loose spikes, 5–8; spikelets distichous, spreading-ascending, 1–2 cm; bracts erect to oblique, leaflike or scalelike, 4–15 mm. Spikelets linear-lanceoid to subterete, 3–6(–10) × 3–4.5 mm; floral scales deciduous, 3, tristichous, reddish brown, oblong-lanceolate, 3–5 × 2–3 mm, apex acute, glossy; prophylls linear, subtending flower. Flowers: perianth bristles separating from achene when mature, white, 0.5–1.2 mm, apex antrorsely roughened or barbed; anthers linear, 2.5–3 mm; connective apices barely 0.1 mm, obtuse, smooth; style as long as stigmas. Achenes yellowish brown, narrowly ellipsoid, dorsiventrally compressed, 4–5 × 1–1.3(–1.7) mm, base cuneate-stipelike, apex acute, beaked, smooth; embryo turbinate with lateral coleoptile and basal root cap (“Carex-type”). 2n = 40.
