Description Rhizome slightly short. Culms tufted, 40-45 cm tall, 1.2-1.5 mm thick, stiff, triquetrous, scabrous on upper part of angles. Leaves longer than culm, flat, blades 10-11 mm wide, stiff, slightly scabrous on veins of lower surface and margins, glabrous, few sheaths brownish, persistent at base. Involucral bracts leaflike, longer than inflorescence, shortly sheathed. Spikes single, terminal, sometimes 1 or 2 lateral spikes borne on middle or lower part of culm, remote, not well developed; terminal spike ovate, 2.5-3 cm, 8-10 mm thick; male part of spike slightly shorter than or equaling female part, oblong, densely many flowered; female part densely many flowered. Female glumes pale greenish laterally, green at middle, ovate or broadly ovate, 4.5-5.5 mm, membranous, 3-veined, thinly several veined on both sides, apex acute or acuminate. Utricles greenish, longer than glume, obovate-oblong, trigonous, 6-6.5 mm, thickly papery, several veined, pubescent on veins, base attenuate into a short stipe, margins densely hispidulous, apex abruptly contracted into a short beak, orifice shortly 2-toothed. Nutlets brown at maturity, obovate-elliptic, trigonous, 4-4.5 mm, base abruptly contracted into a short stipe, apex beakless; style base thickened, conic; stigmas 3. [details]
