Plants densely cespitose. Culms (11–) 15–55 cm. Leaves: sheath summits U-shaped or rounded, occasionally prolonged to 2.5 mm beyond collar; distal ligules 0.5–2.5 mm; blades 3–5 per fertile culm, 5–18 cm × (1.1–) 1.5–2.6 (–3.1) mm. Inflorescences dense or loosely aggregated, gold to medium brown or occasionally dark-brown, 1.1–2.4 cm × 6.3–14 mm; proximal internode (1.5–) 2.5–9.5 mm; 2d internode 1–3 mm; proximal bracts bristlelike. Spikes 4–9, individually distinct or indistinct, usually ovoid, (4.5–) 6–10 × (2–) 4–6 mm, base usually acute, apex rounded to acute. Pistillate scales gold to dark-brown, with whitish to green midstripe, ovate, 1.9–3.5 mm, shorter or slightly longer than perigynia and ± equal in width, margin white, 0–0.2 (–0.4) mm wide, apex obtuse to acute. Perigynia ascending to ascending-spreading, straw colored to light-brown with green distal margins, conspicuously 0–5-veined abaxially, conspicuously 0–4-veined adaxially, at most 1 vein reaching top of achene, lanceovate to ovate, planoconvex or flat, usually constricted near base when dry, 2.1–3.6 × 0.8–1.4 mm, 0.4–0.5 mm thick, margin flat, 0.05–0.15 (–0.2) mm wide, entire, not usually extending to distal body and beak; beak gold to dark-brown at tip, cylindric, unwinged, abaxial suture conspicuously white-margined, or occasionally inconspicuous, distance from beak tip to achene 1–1.6 mm, entire for at least 0.4 mm. Achenes elliptic to quadrate, 1.1–1.4 × 0.7–1 mm, 0.3–0.5 mm thick. 2n = 82.
