Culms densely tufted, erect, ascending, or, rarely, decumbent, 21–39 cm × 0.7–1 mm. Leaves: basal sheaths reddish purple, lustrous; sheaths 5–40 mm; blades lateral, erect or ascending, green, midrib well developed, especially abaxially, 2 lateral-veins developed adaxially, flat to slightly corrugated, 11–29 cm × 0.7–5.2 mm, dead leaves lateral to new clumps, overwintered leaves smooth abaxially. Inflorescences: peduncles of lateral spikes 3–22 mm; of terminal spike (0.9–) 1.2–3.2 (–5.3) cm. Bracts 0.45–3.75 cm × 1.9–4.8 mm, bract blade of distal lateral spikes linear, narrower than spikes, not concealing them (viewed from abaxial surface), widest bract blade of distalmost lateral spike 0.5–3.4 mm wide. Spikes (3–) 4 (–5) per culm; lateral spikes 8–35 × 2.8–4 mm; terminal spike linear, 8–21 × 0.9–2.7 mm, usually exceeded by bract blade of distalmost lateral spike, sometimes sharing sheath with distalmost pistillate spike. Pistillate scales 3.6–3.8 × 1.4–1.6 mm, apex acute to aristate or, occasionally, awned, awn to 0.6 mm, serrulate apically. Staminate scales 3.8–4.8 × 0.8–1.2 mm, margins hyaline (rarely slightly purplish tinged). Anthers 2–2.2 mm. Perigynia 2–7 per spike, conspicuously (22–) 25–32-veined, oblongelliptic, 3.4–4.2 × 1.7–2 mm; beak slightly curved, 0.8–1.3 mm. Achenes ovoid, 1.8–2.2 × 1.4–1.8 mm. 2n = 28.
