Description Herbs perennial. Rhizome short, ligneous. Culms lateral, 3-15 cm tall, compressed trigonous, smooth, covered with pale brown bladeless sheaths at base. Leaves longer than culms; leaf-blade green, flat, leathery, 6-16. 5 mm wide, scabrous on margins, acuminate at apex. Involucral bracts shortly leaf-like, shorter than inflorescences sheathed; sheaths 4-10 mm long, obliquely truncate at orifice. Inflorescence paniculate, with 3 or 4 spikes; terminal spike staminate, linear-clavate, 5- 9 mm long» ca. 2 mm wide, with a short peduncle at base; lateral spikes pistillate, shortly cylindrical, 0. 8-1 cm long, ca. 7 mm wide, loosely 5-7-flowered; peduncles enclosed in sheaths. Staminate scales ovate, pale yellow, 4. 5-5 mm long, obtuse at apex, green 3-veined costa on dorsal surface. Pistillate scales ovate or oblong-ovate, pale green, 6-6. 5 mm long (including awn), acuminate at apex, green 3-veined costa excurrent into a short awn. Perigynia ellipsoid or ovoid (excluding beak), 7-8 mm long, longer than pistillate scales (including beak), obliquely patent, obtusely trigonous, papery, yellowish green, distinctly veined, glabrous, gradually contracted into a ca. 2 cm long beak; orifice 2-lobed with teeth. Stigmas 3; style thicken at base. Achenes tightly enveloped, rhombic-ovoid», trigonous», 4.5-5 mm long Cincluding beak), castaneous, with 3 angles constricted at middle, sides concave above and below, shortly slightly curved, stipitate at base, abruptly contracted into a ca. 1 mm long beak at apex» beak erect, annulate at orifice.
