Description Rhizomes shortly creeping; shoots closely tufted; roots brown; scales brown, soon fibrous. Stems up to 20(–30) cm, bluntly trigonous, striate. Leaves shorter than stems, 1–2 mm broad, flat, dark green; hypostomous; sheaths deep brown, becoming fibrous; ligule c. 1 mm, rounded. Inflorescence 2–4 cm, red-brown. Spikes 2–5, closely contiguous, the upper at the apex of a triangle completed by the next two below, 5–8 mm, subclavate, female at top, male at base. Male glumes 2–3 mm, elliptic; apex obtuse, red-brown. Female glumes c. 2.5 mm, ovate, red-brown, with broad hyaline margin; apex obtuse. Utricles 2.5–4 mm, ovoid, markedly narrowed at base, usually green below and brown above; beak c. 0.5–0.8 mm, smooth, split at the back, with the halves overlapping; stigmas 2; nut obovoid, biconvex.

Description Plants ± loosely cespitose, in small clumps; rhizomes short. Culms weakly erect, sometimes slightly curving, 10–40 cm, smooth or nearly so. Leaves: sheaths pale brown abaxially, inner band hyaline, slightly red tinged, concave at summit; ligules short; blades mid to dark green, flat, 5–15 cm × 1–2 mm, usually shorter than culms. Inflorescences erect, 1–2.5 cm × 5–12 mm; proximal bracts scalelike, usually 2–8 mm, shorter than spikes. Spikes 2–5, lateral spikes gynecandrous, approximate or 1–2 proximal slightly separate, containing 10–20 perigynia, short-oblong to suborbicular. Pistillate scales red-brown with pale brown center and white-hyaline margins, oblong-ovate, subequaling perigynia, apex obtuse. Perigynia ascending, brownish green or in age brownish yellow, lightly or obscurely several-veined, obovate, 2–3.5 × 1–1.5 mm, base round-tapering, membranous; beak abaxial suture evident, entire or with few marginal teeth. Achenes pale to mid brown, elliptic, 1.2–1.5 × 1 mm, dull to slightly glossy. 2n = 64 [details]
