Description Plants perennial; rhizomes 0.25–0.5 mm thick, internodes 5–15 mm, scales fugaceous, rarely evident, translucent, 2 mm. Culms sometimes arching, smooth or 3–12-ridged, terete to sometimes distinctly compressed, 1–60 cm × 0.2–0.5(–0.7) mm, flaccid to rigid. Leaves: distal leaf sheaths persistent or fugaceous, proximally stramineous to red, distally colorless to stramineous or whitish, closely sheathing to prominently inflated, often splitting adaxially, apex rounded (to acute). Spikelets ovoid to lanceoloid or subcylindric, 2–8 × 1–2 mm, apex acute; floral scales 4–25, 4–6 per mm of rachilla, bright reddish or purplish brown to stramineous, midrib region often green, ovate, 1.5–2.5(–3.5) × 1–1.5 mm, midrib prominent to obscure, apex blunt to acute. Flowers: perianth bristles mostly absent, uncommonly 2–4, whitish to pale brownish, slender, obscurely retrorsely and spreading-spinulose, shorter than to equaling achene; stamens 3; anthers yellow to brown, 0.7–1.5 mm. Achenes with angles plus longitudinal ridges ca. 8–12, obscure to prominent, narrowly to broadly obovoid to obpyriform, 2 times to much less than 2 times longer than wide, 0.7–1.1 × 0.35–0.6 mm, trabeculae 30–60, clearly evident to crowded and obscure, spaces between trabeculae sometimes translucent. Tubercles gray to greenish or brownish, pyramidal to much depressed, (0.05–)0.1–0.2 × 0.15–0.25 mm. 2n = 20. [details]
