Description Culms 3–6 cm (fl), elongating to 6–100 cm (fr). Leaves: sheaths adaxially strongly copper colored distally, truncate to convex at mouth, prolonged 2–8 mm beyond base of blade; ligules 1.2–5.8(–9.2) mm; foliage leaf blades 6–50 cm × 2–3 mm. Inflorescences bisexual or, sometimes, nearly or wholly unisexual, flexuous and interrupted, proximal 1–5 branches often separated, decompound, 3–8(–9) × (0.4–)0.8–1.8 cm; basal branch with (2–)4–10 spikes; proximal internode 7–26(–33) mm. Pistillate scales light reddish brown, 2.4–3.3 × (1.1–)1.4–2.1 mm, as wide as or wider than perigynia. Perigynia appressed or ascending, straw colored to light or dark brown, strongly 6–9-veined abaxially, with or without median lengthwise groove near base, sometimes membranous flap toward apex, lance-ovate (body ovate to very widely ovate) in outline, plano-convex, (2.1–)2.3–3(–3.3) × (1–)1.1–1.4 mm, dull; beak 0.8–1.4 mm. Achenes broadly or very broadly trullate-ovate in outline, 1.2–1.6 × 0.7–1 mm. 2n = 66. [details]
