Description Herbs perennial. Rhizome short, ligneous. Culms central, 20-40 cm tall, trigonous, covered with dark brown fibrous sheaths at base. Leaves longer than culms; leaf-blade brownish yellow, flat, revolute, leathery, 7-11 mm wide, acuminate at apex, scabrous on upper margins. Involucral bracts shortly leaf-like, shorter than inflorescence, sheathed; sheaths 1-2. 5 cm long, obliquely truncate at orifice, Inflorescence paniculate, with 3 or 4 spikes; terminal spike staminate, linear-cylindrical, 3-4. 5 cm long, ca. 3 mm wide, with a long peduncle at base; lateral spikes androgynous, cylindrical, 2. 5-4. 5 cm long, 5-6 mm wide, densely flowered, bearing a ca. 1 cm long staminate part at apex, sometimes bearing a few staminate flowers at apex, pedunculate; peduncles exserted from sheaths. Staminate scales oblanceolate-elliptic, reddish brown, 4. 5-5 mm long, acuminate at apex» brown 1-veined costa on dorsal surface. Pistillate scales ovate» reddish brown, 4-5 mm long, acuminate at apex, green 3-veined costa on dorsal surface. Perigynia ellipsoid or ovoid (excluding beak), 5. 5-6 mm long, longer than pistillate scales (including beak), obliquely patent, obtusely trigonous, papery, brown, distinctly veined, glabrous, gradually contracted into a scabrous beak; orifice 2-lobed with teeth. Stigmas 3; style thicken at base. Achenes tightly enveloped, rhombic-ovoid, trigonous» 2.5-3 mm long (including beak), castaneous, sides concave below, shortly curved, stipitate at base, abruptly contracted into a beak at apex, beak coiled, annulate at orifice.
