Description Culms aphyllopodic, smoothly 3-angled, 8–40 cm. Leaves: sheath white-hyaline adaxially, summit U-shaped, smooth; distal ligule 0.5–4.3 mm; blades 0–3 per culm, 12 cm × 1.2–3 mm. Inflorescences green or pale brown, 1.6–3 cm × 7–15 mm; proximal internode (2–)4–8 mm, 2d internode 1.7–4 mm; bracts appressed to ascending. Spikes 3–8, densely clustered except, often, the proximal 1–2, obovoid-oblanceoloid, 10–16 × 5–7 mm, base acute to acuminate, apex truncate. Pistillate scales white- or gold-hyaline with green or gold midstripe, lanceolate to ovate, to 3.5–4.5 mm, shorter than or longer than perigynia. Perigynia appressed, green or gold to light brown, conspicuously 3–12-veined abaxially, 0–9-veined adaxially, wing 0.1–0.15(–0.2) mm wide, narrowly lanceolate, (4.6–)5.5–7.3 × 0.7–1.2 mm, 0.3–0.4 mm thick; beak tip white, green, or gold, narrowly flat, distance from beak tip to achene 3–5 mm, ± ciliate-serrulate. Achenes elliptic to ovate, 1–1.8 × 0.6–0.8 mm, 0.3–0.4 mm thick. 2n = 64.
