Description Herbs perennial. Rhizome short, ligneous, thick. Culms lateral, 15-40 cm tall, obtusely trigonous, covered with brown bladeless sheaths at base. Leaves longer than culms; leaf-blade green or yellowish green, flat, revolute, leathery, 5-12 mm wide, acuminate at apex» scabrous on margins. Involucral bracts shortly leaf-like, shorter than inflorescence, sheathed; sheaths 0. 6-1. 5 cm long, obliquely truncate at orifice. Inflorescence paniculate, with 3 or 4 spikes; terminal spike staminate, clavate or clavate-cylindrical, 1. 5-2 cm long, 3. 5-4 mm wide, with a peduncle at base; lateral spikes pistillate, cylindrical, 2-3. 5 cm long, 8-10 mm wide, densely flowered, pedunculate; peduncles slightly exserted from sheaths, or enclosed. Staminate scales oblong or elliptic, pale yellow, 5. 5-6 mm long, acute at apex, brown 1-veined costa on dorsal surface. Pistillate scales ovate to broadly ovate, yellowish green, 4-4. 5 mm long including awn), acuminate at apex, green 3-veined costa excurrent into a short awn. Perigynia broadly ovoid or ovoid (excluding beak), 6. 5-7 mm long, longer than pistillate scales (including beak), obliquely patent, obtusely trigonous, papery» yellowish green or green, distinctly veined, glabrous, gradually contracted into a ca. 2 mm long beak; orifice 2-lobed with short teeth. Stigmas 3; style thicken at base. Achenes tightly enveloped, rhombic-ovoid, trigonous, 4-4. 5 mm long (including beak) , yellowish brown or castaneous, sides concave below, shortly erect, stipitate at base, abruptly contracted into a beak at apex, beak erect, annulate at orifice.
