Description Rhizomes 0.8–1.9 mm thick, shoots often arising 2–several per cluster, many nodes without shoots. Culms bluntly trigonous, (8–)15–40 cm, smooth-angled distally. Leaves: basal sheaths pale to dark brown; sheaths with hyaline inner band, apex not prolonged, glabrous; ligules 0–2.8 mm; blades 1–3(–3.5) mm wide. Inflorescences dense, headlike, 1.2–3.5(–4.5) cm, 1/2+ as wide as long (if pistillate); spikes 6–20(–25), usually unisexual; staminate spikes lanceoloid; pistillate spikes ovoid. Pistillate scales pale brown to ± whitish hyaline, hyaline margins, lanceolate to ovate, (4.3–)4.7–7.5 mm, apex acute to acuminate, satiny to ± dull. Anthers (2.5–)2.8–3.9 mm, apiculus bristly (30X). Perigynia brown, essentially veinless, usually stipitate, ovate to broadly elliptic, ± plano-convex, (3–)3.5–4.2(–4.8) × 1.2–2.1 mm, dull; beak (0.9–)1.2–1.9 mm, apex hyaline, friable, oblique or obscurely bidentulate. [details]
