Culms (1–)2–90 cm. Leaves: sheaths adaxially whitish, conspicuously red dotted, truncate or convex at mouth, prolonged 0.4–4(–6) mm beyond base of blade; ligules 8–57 mm; foliage leaf blades 14–30(–47) cm × 1–2.5 mm. Inflorescences bisexual, straight, little interrupted, ± compound (short branch at least on most proximal node or, occasionally, unbranched) , 2–5(–6) × 0.6–1.4(–1.7) cm, proximal 0–3 branches slightly overlapping 1 above; basal branch (when present) with 2–12 spikes; proximal internode 3–7(–10) mm. Pistillate scales straw colored or brownish, 1.5–2.7 × 0.9–1.6 mm, as wide as perigynia at base, narrower distally. Perigynia ± spreading, olive to dark chestnut brown, stongly 4–6-veined and finely 2–4-veined abaxially, with narrow median strip extending full length (grooved aspect emphasized by pair of bordering veins), often membranous flap toward apex, narrowly deltoid-ovoid, unequally biconvex, (2–)2.3–2.5(–2.9) × 1–1.4 mm, shiny; beak 0.9–1.1 mm. Achenes broadly compressed-ovoid, 1.4–1.7 × 0.7–1 mm. 2n = 48, 50, 54, 60.
