Description Perennial; rhizome short, covered with dark brown fibrous remains of old leaf sheath. Culms central, 10–30 × ca. 0.1 cm, trigonous, usually prostrate on the ground. Leaves basal, green, blades linear, 15–40 × ca. 0.5 cm, flat, glabrous on both surfaces, apex acuminate, margins antrorsely scabrous, base gradually narrowed. Bracts leafy, the lowermost one surpassing inflorescence, sheathing, sheath ca. 5 mm long, green. Inflorescence paniculiform, contracted, head like, comprising 2–3 crowded spikes; terminal spike staminate, 8–12 × 1 mm, linear-cylindrical, with peduncle ca. 5 mm; lateral spikes pistillate, 5–15 × ca. 5 mm, cylindrical, with peduncle 5–8 mm long, loosely flowered, with 1–10 flowers. Staminate glumes ca. 3 mm, ovate, membranous, glabrous, middle vein green, apex rounded; pistillate glumes ca. 6 mm, ovate-lanceolate, membranous, glabrous, middle vein green, middle vein excurrent into a short awn for ca. 2 mm. Perigynia longer than the glumes, green, 7–10 × 3 mm, fusiform, obscurely trigonous, membranous, glabrous, many veined, apex attenuate into a beak for ca. 2 mm. Nutlet ca. 7 mm long, brown to dark brown, tightly enveloped by the perigynium, ovate-rhomboid, trigonous with angles constricted at the middle, base shortly stipitate, apex abruptly contracted into a curved short beak of 1 mm; persistent style, base thickened.
