Plants perennial, cespitose, (5–)10–60 cm, bases hard, glabrous; rhizomes absent. Leaves polystichous, mostly spreading-excurved, to 1/2 as long as culms; sheaths usually entire; ligule absent; blades linear, 2–3 mm wide, flat or shallowly involute, margin scabrid, apex blunt. Inflorescences: simple or compound anthelae with numerous small pedunculate clusters of sessile spikelets; scapes linear, distally terete, 1–2 mm thick; involucral bracts short, usually shorter than inflorescence. Spikelets greenish brown or yellow-brown, ovoid, 2–3 mm; fertile scales broadly ovate, 1–1.5 mm, obtuse or apically notched, midrib not excurrent. Flowers: stamens usually 1; styles 2-fid, slender, glabrous. Achenes dark brown to nearly black, tumidly obovoid, rarely obscurely 3-ribbed, 1 mm, faintly striate to variously warty, faintly reticulate. 2n = 56.
