Description Herbs perennial. Rhizome short, ligneous, thick. Culms lateral, 20-60 cm tall, trigonous, with dark brown fibrous sheaths at base. Leaves shorter to longer than culms; leaf-blade brownish green, flat, leathery, 3-10 mm wide, acuminate at apex, margins scabrous, revolute. Involucral bracts shortly leaf-like, shorter than inflorescence, sheathed; sheaths 1-5 cm long, obliquely truncate at orifice. Inflorescence paniculate, with 4 to many spikes» rarely 2 or 3; terminal spike staminate» clavate, 3-6 cm long, ca. 5 mm wide, with a long peduncle at base; lateral spikes androgynous, single to ternate at each node, cylindrical, 2-6 cm long, 7-12 mm wide, densely flowered, bearing a 1. 5-3 cm long staminate part at apex, pedunculate; peduncles exserted from sheaths. Staminate scales elliptic, yellowish brown or brown, 7-8 mm long (including awn), emarginate at apex, brown l-veined costa excurrent into a 3-4 mm long scabrous awn. Pistillate scales ovate, brown, 6-7. 5 mm long (including awn), emarginate at apex, brown 3-veined costa excurrent into a ca. 2. 5-4 mm long scabrous awn. Perigynia broadly ovoid (excluding beak), 5-7 mm long, longer to shorter than pistillate scales (including beak), obliquely patent, obtusely trigonous» subleathery, yellowish brown, distinctly veined, glabrous, gradually contracted into a ca. 2.5 mm long beak; orifice 2-lobed with long teeth. Stigmas 3; style slightly thicken at base. Achenes tightly enveloped, rhombic-ovoid, trigonous, 2. 5-4 mm long (including beak), yellowish brown or castaneous, sometimes with 3 angles constricted at middle, sides concave above and below, shortly curved, stipitate at base, abruptly contracted into a 0.5-1.2 mm long beak at apex, beak slightly curved or coiled. [details]
