Description Plants perennial, densely cespitose, 30–60(–90) cm; rhizomes forking, compact. Culms lax, leafy toward base, filiform, ± terete. Leaves ascending, exceeded by culm; blades filiform, to 0.5 mm, margins mostly involute, apex trigonous, tapering. Inflorescences mostly lax cymes or clusters of cymes, 1–2, sparse, turbinate, branches capillary; leafy bracts setaceous, exceeding proximal cymes, shorter than, equaling or slightly exceeding distal cymes. Spikelets red brown, fusiform lanceoloid, 5 mm, apex acute; fertile scales lanceolate, 3.5–4.5 mm, apex acute or acuminate, midrib included or short excurrent. Flowers: perianth bristles 6, exceeding tubercle base, antrorsely barbellate, basally setose. Fruits 1 per spikelet, 2.8–3 mm; body pale brown, obovoid pyriform, tumidly lenticular, 1.5–1 × 1 mm; surfaces transversely wavy rugose, intervals vertically striate with narrow, raised alveolae; tubercle flat, narrowly triangular-subulate, (0.8–)1–1.5 mm. [details]
