Stolons short to (rarely) 15 cm. Culms loosely cespitose, usually slightly arched, 15–30 cm, thin. Leaves: sheaths brownish purple, throats rounded, densely pilose; basal leaves flat, 8–15 cm × 3–5 mm, not reaching inflorescences, margins pubescent; cauline leaves 1–3, smaller than basal, not reaching inflorescences. Inflorescences corymbose, proximal branch longest; glomerules 8–15 (each with 3–5 flowers, sometimes reduced to 1–2 flowers), pedunculate, capitate or spicate; branches mostly arching in same direction (often branching at apex); proximal inflorescence bract bladeless; bracts and bracteoles brown, ciliate. Flowers: tepals light brown, (margins ± ciliate, apex acuminate, usually distinctly awned), 1.8–3 mm; anthers ± equaling filament length. Capsules brown, ellipsoid, shorter than tepals; (beak short). Seeds brown (with few hairs present), 1 mm, few hairs present; caruncle generally indistinct. 2n = 36.
Phenology: Flowering and fruiting summer.
Habitat: Rocky to gravelly snow patches on mountains, dry to mesic meadows, and patches of bare soil in heaths
Elevation: 50–2500 m
Distribution
