Description Plants cespitose. Culms acutely angled, 30–115 cm, scabrous. Leaves: basal sheaths red-brown, indistinctly ladder-fibrillose; sheaths of proximal leaves glabrous, fronts with red-brown spots, veinless, apex U-shaped; blades 3–5 mm wide. Inflorescences: proximal bract subequal to inflorescence, 2–4 mm wide. Spikes erect; proximal 2–3 spikes pistillate, 1–5 cm × 4–6 mm, base obtuse; terminal 1–2 spikes staminate. Pistillate scales red-brown, longer than perigynia, apex acute or acuminate, awnless. Perigynia divergent, olive-brown with red-brown spots on apical 1/2, veinless, inflated, loosely enclosing achenes, obovoid, 1.5–2.8 × 1.5–2 mm, dull, apex rounded, papillose; beak green, 0.1–0.2 mm. Achenes not constricted, glaucous. 2n = 54. [details]
