Description Rhizomes very shortly creeping; shoots loosely tufted; roots pale brown or whitish; scales pale or pink-brown, usually persistent. Stems 10–50 cm, rough above, slender, sharply trigonous, scarcely ribbed. Leaves 15–55 cm × 2–3 mm, soft, thin, flat or ± keeled, tapering gradually to a fine, rough, ± flat tip, pale green; amphistomous but with stomata mostly on underside; sheaths thin, forming short false stems only, lower pink-brown, soon decaying; inner face hyaline; apex ± straight; ligule 2–3 mm, acute. Inflorescence 3–5 cm; bracts glumaceous, lower sometimes setaceous. Spikes 4–8, contiguous or ± distant, 5–8 mm, female at top, male at base. Male glumes 2.5 mm, ovate or broadly elliptic, hyaline, with green midrib; apex obtuse. Female glumes c. 2 mm, ovate-oblong, hyaline, with green midrib; apex acute or apiculate. Utricles 2–3 mm, ovoid-ellipsoid, plano-convex, pale or blue-green to yellow, with yellowish ribs; beak 0.5–0.75 mm, minutely rough, notched; stigmas 2; nut obovoid or ellipsoid, biconvex. [details]

Description Perennials. loosely tufted, with short rhizomes. Stems erect, trigonous, scabrous above, 25–50 cm tall. Leaves shorter than stem, 2–3 mm wide, margins scabrous. Basal sheaths pale brown to brown, bladeless. Involucral bracts scalelike, proximal ones sometimes setaceous. Inflorescences spikes 4–8, sessile, gynaeandrous, ovate-oblong, 6–10 mm long, 3–4 mm wide, upper spikes congested, lower ones remote. Staminate scales pale green, apex acute. Pistillate scales pale green, ca. 2 mm long, apex acute. Perigynia slightly longer than pistillate scales, ovate or elliptic, plano-convex, 2–2.2 mm long, ca. 1.2 mm wide, 5–12-veined on both faces, apex abruptly contracted into a slightly scabrous short beak, mouth emarginate. Achenes elliptic or ovate, plano-convex, ca. 1.5 mm long. Stigmas 2. [details]
