Description Herbs perennial. Rhizome short, ligneous. Culms lateral, 30-70 cm. tall, trigonous, covered with dark brown sheaths at base. Leaves longer than culms; leaf- blade brownish yellow, flat, leathery, 6-8 mm wide, acuminate at apex, scabrous on upper margins. Involucral bracts shortly leaf-like, shorter than inflorescence, sheathed; sheaths 1-2 cm long, obliquely truncate at orifice. Inflorescence paniculate, with 4 or 5 spikes; terminal spike staminate, linear-cylindrical, 4-7. 5 cm long, ca. 2.5 mm wide, with a long peduncle at base; lateral spikes androgynous, cylindrical, 5-7. 5 cm long, 8- 9 mm wide, densely flowered, bearing a 2-3.5 cm long staminate part at apex» pedunculate; peduncles exserted from sheaths. Staminate scales lanceolate, pale brown, 6. 5-7 mm long, acuminate at apex, brown l-veined costa on dorsal surface. Pistillate scales narrowly ovate, pale brown, 5-5. 5 mm long, acuminate at apex, green 3-veined costa excurrent into a short awn. Perigynia broadly ovoid (excluding beak), 6-7 mm long, longer than pistillate scales (including beak), horizontally patent at maturity, obtusely trigonous, papery» yellowish brown, distinctly veined, glabrous, gradually contracted into a ca. 3 mm long beak; orifice 2-lobed with short teeth. Stigmas 3; style thicken at base. Achenes tightly enveloped, rhombic-ovoid, trigonous, 2-2. 5 mm long
(including beak), yellowish brown or castaneous, with 3 angles constricted at middle, sides concave above and below, shortly curved, stipitate at base, abruptly contracted into a short beak at apex, beak coiled.
