Description Plants loosely cespitose; rhizomes appearing elongate in old clumps. Culms typically (3–)5–9 per clump, 25–85(–150) cm; vegetative culms inconspicuous, usually fewer than 10 leaves clustered at apex, not strikingly 3-ranked. Leaves: sheaths with adaxial hyaline area, not mottled abaxially, frequently puckered or cross-corrugated, summits truncate or U-shaped, rarely slightly V-shaped, at most shortly prolonged beyond collar, papillose (at 30X); distal ligules 1.5–3.5 mm; blades 2–4 per fertile culm, 10–28(–40) cm × 2–4 mm. Inflorescences erect, compact on tallest culms, dense, brown, 1.2–2.5(–3.5) cm × 8–12(–15) mm; proximal internode 1.5–6(–10) mm; 2d internode 2–3.5 mm. Spikes 4–11, ± overlapping, ellipsoid or globose, 5.5–10 × 3.6–6.5 mm, base usually acute, apex rounded to broadly acute; proximal bracts scalelike, often with bristle tips shorter than inflorescences. Pistillate scales reddish brown or dark brown, ovate to lanceolate, 2.4–3.5 mm, at least slightly shorter than perigynium beaks, narrower than perigynia, apex acute or somewhat obtuse. Perigynia spreading to ascending-spreading, tan to brown at maturity, contrasting with scales while maturing, conspicuously at least 4–8-veined abaxially, 3–7-veined adaxially, broadly ovate, plano-convex, 3.5–4.5(–4.7) × (1.4–)1.6–2.4 mm, 0.45–0.6 mm thick, margin flat, including wing 0.25–0.45 mm wide, smooth; beak golden to dark brown tinged at tip, flat, ciliate-serrulate, abaxial suture with golden to dark brown hyaline margin, distance from beak tip to achene 1.7–2.3 mm. Achenes ovate to broadly elliptic, 1.3–1.6 × 0.9–1.2 mm, 0.4–0.55 mm thick. n = 36+IV. [details]
