Description Herbaceous perennial. Rhizome woody, creeping or obliquely ascending, with many brown, fibrous adventitious roots. Culms loosely caespitose, 35–80 cm tall, acutely trigonous, slender to thick, upper parts scabrous, base with pale brown to dark brown bladeless sheaths. Leaves cauline, shorter than culms, 2.5–5 mm wide, flat, scabrous on both surfaces; sheaths not overlapping, 5–10 cm long, sparsely pubescent on the surface, but densely on the angles. Bracts leaf-like; lowermost 2 or 3 bracts shorter than inflorescence, with a 7–23 mm long sheathing base; upper ones longer or equaling the inflorescence, with a 3–5 mm long sheathing base or sheathless. Spikes 4–8, sparse in the base of the inflorescence, aggregated in the apex of the inflorescence; terminal staminate spikes 3 (rarely 2), narrowly clavate, 4–15 mm long, 1–1.5 mm wide; others pistillate, cylindrical, 1–3.6 cm long, 3.8–4.2 mm wide, ± densely flowered; lower peduncles extending to the apex of the bract sheaths, the upper ones enclosed. Staminate scales elliptic, yellowish brown, 4.5–5.5 mm long, apex obtuse, with yellow 1-veined costa excurrent into a 0.5–0.7 mm long scabrous awn. Pistillate scales ovate, pale brown to pale yellow, 2.5–2.8 mm long, apex mucronate, with green 3-veined costa. Utricles nearly erect or slightly patent, obovoid, obtusely trigonous, pale brownish green, longer than pistillate scales, 3.8–4.2 mm long, densely whitish hispidulous, lower part with 7 or 8 veins, base attenuate and short-stipitate, apex abruptly contracted into a 1–1.5 mm long erect beak, orifice with 2 short teeth. Achenes tightly enveloped by utricles, obovoid, trigonous, brown, 1.8–2.2 mm long, base short-stipitate, apex emarginate; style erect, base slightly thickened; stigmas 3. [details]
