Description  Plants densely cespitose. Culms 20–100 cm; vegetative culms with few leaves clustered at apex. Leaves: sheath summits U-shaped; distal ligules 2.3–4.8 mm; blades 3–5 per fertile culm, 10–32 cm × 1.4–3(–3.5) mm. Inflorescences arching or nodding, dense or open, green, yellow, or brown at maturity, 1.5–6 cm × 5–20 mm; proximal internode 2–12 mm; 2d internode 2–13 mm; proximal bracts scalelike, with bristle tip. Spikes 3–10, distinct, ellipsoid, 7–16 × 3–9(–13) mm, base acute to short-attenuate, apex acute to rounded. Pistillate scales hyaline brown, occasionally with green or gold midstripe, lanceolate, 3.4–4 mm, shorter and narrower than perigynia, apex acuminate. Perigynia ascending or rarely widely spreading, golden brown, conspicuously 5-veined on each face or fewer adaxially, winged to base, lanceolate, flat except over achene, 4.2–6.8 × 1.2–2 mm, length at least 3 times width, 0.35–0.55 mm thick, margin flat, including wing 0.2–0.6 mm wide; beak pale to golden-brown at tip, flattish, ciliate-serrulate, abaxial suture with white or golden brown hyaline margin, distance from beak tip to achene 2.2–4.8 mm. Achenes ovate or elliptic, 1.3–1.7 × 0.7–0.9 mm, 0.3–0.4 mm thick. [details]
