Description Culms 5–120 cm. Leaves: sheaths adaxially strongly dotted purplish red, concave at mouth, not prolonged beyond base of blade; ligules 1.2–5.8 mm; foliage leaf blades 10–80 cm × 2.5–5.5(–7) mm. Inflorescences bisexual, evidently paniculate, proximal 3–9 branches well separated, (6–)7–15(–18) × 1–4.2 cm; basal branch with 9–33(–48) spikes; proximal internode 6–27 mm. Pistillate scales translucent with green center, 1.6–2.4 × 1–1.6 mm, shorter, narrower than perigynia. Perigynia spreading, deep olive green to brown, 8–11-veined abaxially, with or without slight median lengthwise depression, without membranous flap toward apex, obpyramidal or obovoid (body very widely obovoid or widely depressed-obovoid), unequally biconvex, 1.8–2.6 × 1.4–2 mm, shiny; beak 0.4–0.7 mm. Achenes oblong-ellipsoid to widely ellipsoid, 1.4–1.7 × 0.8–1 mm. 2n = 60, 64, 66. [details]
