Plants cespitose, short-rhizomatous. Culms brown at base. Leaves: basal sheaths ± fibrous; sheath fronts membranous; blades V-shaped in cross-section when young, or filiform or channeled, widest leaves 1–4 mm, glabrous. Inflorescences racemose, with 3–6 spikes; proximal nonbasal bracts leaflike, often short, long-sheathing, sheath more than 4 mm, longer than diameter of stem; lateral spikes pistillate, spreading or pendent, pedunculate, peduncles longer than spikes (spikes erect or on short peduncles in artic and high mountain plants), prophyllate; terminal spike staminate, gynecandrous, or androgynous. Proximal pistillate scales with apex obtuse to acute. Perigynia ascending, not speckled redbrown, veinless except for 2, strong, marginal veins or weakly 2–10-veined, stipitate, lanceolate to narrowly ovate, obtusely trigonous in cross-section, base rounded, apex contracted or tapering to beak, glabrous; beak 0.3–1 mm, margins entire or serrulate, orifice entire or subentire. Stigmas 3. Achenes trigonous, almost as large as perigynia, glabrous; style deciduous.
