Description Perennial herbs. Rhizomes short, indurate. Culms 25–55 cm tall, 0.5–1 mm thick, trigonous, glabrous, smooth, with yellowish brown, persistent bladeless sheaths at base. Leaves shorter than culms, rarely equal in length; blades 1.5–3 mm wide, flat, scabrous on dorsal surfaces. Involucral bracts leaf-like, terminal 1 or 2 longer than inflorescence,
lower bracts shorter, sheathed; sheaths 5–25 mm long, with the lowest longer than others. Spikes 4–6, androgynous, cylindrical, 10–30 mm long, 3–4 mm wide; terminal 2 or 3 spikes closed, others remote; peduncles slightly exerted from sheaths, or enclosed; staminate part shorter than pistillate part, 3–6 mm long, densely flowered, pistillate part 5–25 mm long, sparsely flowered. Staminate scales oblong-lanceolate, 4.5–5 mm long (including awn), pale yellowish brown, acuminate at apex, green 3-veined costa extending 0.5–1 mm long scabrous awn at apex. Pistillate scales narrowly elliptic-lanceolate, 6.5–7 mm long (including awn), greenish white, acuminate at apex, green 3-veined costa extending 3–4 mm long scabrous awn at apex. Perigynia narrowly ellipsoid, trigonous (excluding beak), shorter than pistillate scales (including beak), 4–4.5 mm long, greenish yellow, membranaceous, whitish pubescence, conspicuously thinly veined, attenuate and stipitate at base, gradually contracted into a short beak at apex; orifice 2-lobed with short teeth, sparsely pubescent at margins. Achenes tightly enveloped, oblong-obovoid, trigonous, castaneous, ca. 2.2 mm long, abruptly attenuate and curved stipitate at base, shortly beaked at apex; style glabrous, thickened and curved at base; stigmas 3.
