Description Slender annual with fibrous roots, 12‒50 cm tall. Culms tufted, trigonous, striate, scabrous, 0.5‒1.2 mm wide. Leaves all basal, shorter than the stem. Lamina flat, straight, 1‒1.5 mm wide, glabrous, margins in lower part hyaline, spotted with brown flecks. Involucral bracts 2‒4, glume like, shorter than the spikelet, smooth. Inflorescence simple or once compound, open, consisting of 1‒5 primary rays obliquely erect. Spikelets solitary, ovoid or almost globular, obtuse, many-flowered, erect, 5‒12 mm long, 3‒6 mm wide, pale brown to brown. Stamens 3; anthers linear, connective smooth, 1.8‒2 mm long. Glumes spirally arranged, ovate, or broadly ovate, 3.5‒5 mm long, light brown to brown with red-brown glandular markings, surface glabrous, apex acute, margin ciliate, keeled without nerves; rachilla persistent on rachis after glumes and achenes have fallen off, narrowly winged. Style as long as stigmas, triquetrous, glabrous, base prominently enlarged, triangular, surface with short, turgid hairs. Stigmas three. Achene broadly obovoid or obpyriform, trigonous, apex truncate, base rather prominently stipitate, lobes at the distal end decurrent on achene angles; 1.2‒1.4 mm long, 0.8‒1 mm wide, smooth, epidermal cells isodiametric.
