Description Plants densely cespitose. Culms 20–110 cm. Leaves: sheath adaxially white-hyaline, summits usually U-shaped, occasionally prolonged to 3 mm beyond collar; distal ligules (1–)2–3(–6) mm; blades (2–)3–7 per fertile culm, 10–50 cm × 2–5 mm. Inflorescences usually dense, light to dark brown and green, (0.8–)1.1–2.6 cm × 9.5–17.5 mm; proximal internode 0.5–3(–4) mm; 2d internode 0.5–2(–3) mm; proximal bracts scalelike or rarely leaflike, occasionally bristlelike, shorter than inflorescences. Spikes 4–10(–14), densely aggregated, individually indistinct, usually broadly ovoid, 5–9(–11) × 4.3–7 mm, base and apex rounded or sometimes acute. Pistillate scales brown, often red, purple, or coppery tinged, with pale or green midstripe, ovate, 2.4–3.5 mm, shorter than and narrower or as wide as perigynia, white margin 0–0.1 mm wide, apex acute. Perigynia ascending to spreading, green or straw colored to brown when mature, conspicuously (0–)3–8(–11)-veined abaxially, conspicuously 0–8-veined adaxially, veins usually not reaching top of achene, ovate to broadly ovate, flat except over achene or ± plano-convex because of air within, (2.8–)3.4–4.5(–5.2) × 1.1–2.4 mm, 0.3–0.5 mm thick, margin flat, including wing 0.2–0.5 mm wide, ciliate-serrulate at least on distal body, without metallic sheen, dull to slightly shiny; beak tip gold or red-brown to dark brown, cylindric, unwinged, at least 1 mm, ± entire for 0.2–0.6(–0.9) mm, abaxial suture inconspicuous or with white margin, distance from beak tip to achene 1.5–2.5(–2.8) mm. Achenes ovate to obovate, 1.1–1.6 × 0.7–1.2 mm, 0.3–0.5 mm thick. 2n = 80, 90. [details]
