Description Rhizomes 1–4 mm diam., tough, hard. Culms ridged, 10–70 cm × 0.5–2 mm, hard, without evident internal air cavities. Leaves 5–10; sheaths loose, the proximal often disintegrating to prominent fibers, often stramineous or brownish, papery, fronts membranous-hyaline with delicate veins, summit slightly concave with V-shaped veinless area and often disintegrating; blades 0.5–1 times as long as culms, hard, without evident internal air cavities; distal blades 3–30 cm × 0.5–2 mm, longer than sheaths, margins sparsely antrorsely spinulose or papillose, apex sharply acute. Inflorescences: proximal involucral bract 1–15 cm, resembling foliage leaf blade. Spikelets ovoid to lanceoloid or terete, 5–20 × 3–5 mm; scales pale to dark red-brown, midribs usually stramineous, smooth; proximal 1 or 2 scales often resembling involucral bracts, with awnlike blades, to 15 mm; other scales in proximal part of spikelet prominently 9-veined, ovate, 4 × 3 mm, papery to often cartilaginous, margins hyaline, ciliolate, apex entire, acute to rounded. Flowers: perianth bristles pale brown, unequal. Achenes greenish to orange-brown, broadly obovoid, 2–2.3 × 1.5–1.7 mm.
