Description Rhizomes 0.6–1.8 mm thick, shoots often arising 2–several per cluster, many nodes without shoots. Culms bluntly trigonous, (6–)10–35 cm, smooth-angled distally. Leaves: basal sheaths grayish brown to dark brown, shredding into fibers; sheaths with hyaline inner band, apex not prolonged beyond base of blade; ligules 0–0.8 mm, glabrous; blades 0.6–1.8 mm wide. Inflorescences 0.7–2 cm, 1/2+ as wide as long (if pistillate); spikes 3–8, androgynous, ovoid. Pistillate scales dark reddish brown, with hyaline margins, broadly ovate, 2.4–4.1 mm, apex acute to acuminate, shiny. Anthers 1.4–3 mm, apiculus smooth to warty, very short and broad (30X). Perigynia dark reddish brown, essentially veinless, ± stipitate, broadly ovate to nearly orbicular, thickly plano-convex, 2.4–3.9 × 1.5–2.1 mm, shiny; beak 0.3–0.9 mm, hyaline, weakly bidentulate or oblique.
