Description Plants perennial, densely cespitose or solitary, 10–100 cm; rhizomes absent. Culms mostly lax, ascending to leaningexcurved, leafy, linear to filiform, terete. Leaves shorter than culm; blades ascending, filiform to narrowly linear, proximally flat, 0.5–1.5(–2.5) mm wide, margins distally strongly involute, apex trigonous, tapering. Inflorescences: spikelet clusters 1–3(–4), proximalmost distant, dense to sparse, narrowly turbinate to hemispheric; peduncles and branches ascending; leafy bracts linearsetaceous, mostly overtopping clusters. Spikelets redbrown, ovoid to lanceoloid, (3.5–)4–5 mm, apex acute; fertile scales ovate, 3–4.5 mm, apex acute, mucronate to awnedcuspidate. Flowers: bristles 6, mostly reaching tip of tubercle or beyond, antrorsely barbellate. Fruits 1–3 per spikelet, (2.5–)3–3.5(–4.1) mm; body dark brown with small pale center, lenticular, broadly ellipsoid to suborbicular, 1.3–2.1 × 1.3–1.5 mm, smooth, margins narrow, flowing into tubercle; tubercle triangular-subulate, compressed, mostly 1.5–2 mm.
