Description Rhizomes short; shoots tufted; roots pale yellow-brown; scales brown, red-brown, or blackish, becoming fibrous in decay. Stems 6–30(–40) cm, trigonous. Leaves 5–20 cm × 1.5–3 mm, mid green, not glaucous, ± flat or keeled, gradually tapered to a short, fine trigonous point; hypostomous; sheaths white with green veins, becoming red, red-brown, or brown, persistent, inner face hyaline; apex straight; ligule 0.5–1 mm, obtuse. Inflorescence a compact, terminal cluster of 1–4 subglobose, erect spikes, terminal one female at top and male at base (often detectable only by presence of white filaments), the rest female; upper bracts glumaceous, lower bracts leaf-like, exceeding inflorescence, lowest not or scarcely sheathing. Male glumes 2–2.5 mm, lanceolate-elliptic, dark red-brown with pale midrib; apex acute. Female glumes 1.5–2 mm, ovate, red-black with narrow pale midrib; apex acute. Utricles 2–2.5 mm, obovoid-ellipsoid, minutely papillose, greenish-brown; beak 0.25 mm, slightly notched; stigmas 3; nut ellipsoid, trigonous. [details]

Description Plants densely cespitose. Culms 5–35 cm, distally scabrous. Leaves 2–3 mm wide. Inflorescences: proximal bracts shorter than or exceeding inflorescences; spikes globose or oblong, 4–10 × 3–6 mm; lateral 1–2(–3) spikes pistillate, distant, distinct, erect, short-pedunculate; terminal and distal lateral spikes overlapping, sessile, forming dense terminal cluster; terminal spike gynecandrous. Pistillate scales dark brown or black, margins hyaline, ovate, shorter than or equaling and as broad as perigynia; midvein same color as body, inconspicuous. Perigynia ascending, green becoming dark brown or purple-black, veinless, elliptic or obovate, 2–2.5 × 1.25–1.5 mm, often serrulate distally, apex abruptly beaked, papillose; beak 0.2–0.3 mm, shallowly bidentate, smooth or serrulate. Achenes nearly filling body of perigynia. 2n = 56. [details]
