Description Plants perennial, cespitose, 20–90 cm, base pale brown to dark brown; rhizomes absent or compact, knotty, scaly. Culms erect to arching-ascending, leafy, wand-like. Leaves mostly basal, few and increasingly distant upculm, shorter than scape; blades narrowly linear, concave proximally, (1–)2–3 mm wide, tapering and increasingly involute-sulcate proximally, margins scabrid, apex triquetrous, tip narrow but blunt. Inflorescences: clusters 1(–2), if 2 then close together, dense, broadly turbinate to hemispheric; primary leafy bracts linear, stiff, exceeding clusters. Spikelets light brown, narrowly lanceoloid, 8–10 mm, apex acuminate; fertile scales lanceolate, convex, (6–)7–8 mm, apex narrowly acute, low midrib short-excurrent or not. Flowers: perianth bristles 6, excurved, plumose from base to midbristle, 5–7.5 mm, antrorsely barbellate to tip. Fruits 1–2 per spikelet, 2.3–2.6 × 1.1–1.2 mm; body brown, short-stipitate, tumidly obovoid, subterete, 1.8–2 mm, margin low, broad; surfaces interruptedly transversely wavy-rugulose; tubercle broadly and concavely conic, 0.5–0.7 mm high, base shallowly 2-lobed, discoid, abruptly narrowed to blunt tip.
