Description Plants densely cespitose, in small clumps; rhizomes short. Culms erect to arching, slender, 15–90 cm. Leaves: sheaths relatively tight, pale to mid brown abaxially, inner band thin and hyaline, often concave at summit; ligules as long as wide; blades green to yellowish green, flat, 10–25(–40) cm × 0.5–2 mm, shorter than culms. Inflorescences erect to somewhat nodding, 1.5–7 cm × 3–6 mm; proximal bracts bristlelike-prolonged, shorter than to exceeding spikes; distal bracts usually scalelike. Spikes 5–10, gynecandrous, proximal ± separate, distal closely approximate, containing 5–10 perigynia, sessile, globose to short-oblong, 3–7 × 3–4 mm; terminal spike staminate for less than 1/2 of length, scarcely clavate. Pistillate scales white-hyaline with green, 3-veined center, often brown tinged, ovate, subequal to, not concealing perigynia, apex obtuse to acute. Perigynia appressed-ascending to loosely spreading at maturity, green or brown, often dark brown in age, lightly several-veined, elliptic-ovate, 2–2.5 × 0.8–1.5 mm, widest near middle, membranous; beak shor, margin serrulate. Achenes pale to mid brown, ovate-orbiculate, 1.25–1.5 × 0.8–1 mm, glossy. 2n = 56. [details]
