Culms densely cespitose, reddish, 3–33 cm, base thick, extending 1–8 cm into soil. Leaves: sheath throats densely hairy; basal leaves erect, channeled, linear, 2–15 cm × 1–4 mm, apex not callous; cauline leaves 2–3. Inflorescences panicles of dense, nodding, spikelike clusters (each 1–25 mm), often interrupted by 10–70 mm; proximal inflorescence bract conspicuous, generally exceeding inflorescence; bracts clear; bracteoles clear, margins ciliate, apex narrow, extended. Flowers: tepals brown with clear margins or very pale throughout (outer whorl bristle-pointed), 2–2.5 mm; outer whorl longer than inner whorl; anthers ± equaling filaments. Capsules pale to dark brown or blackish, round (apex ± acute), generally shorter than tepals, apex ± acute. Seeds brown, cylindric-ovoid, body 1–1.2 mm; caruncle 0.2 mm. 2n = 24.
Phenology: Flowering and fruiting summer.
Habitat: Alpine slopes and heaths, dry or damp situations among grasses, herbs, or lichens, and in subalpine forests
