Distribution: Boreal circum-polar; in C. Asia south to Tian Shan Mts., Pakistan and Kashmir; also New Guinea, Australia and S. America.

Perennial, sometimes tufted, 20-45 cm. Rhizome short. Stem sharply trigonous, greyish green, papillose and scabrous especially along edges. Leaves shorter than stem; sheaths to 90 mm, soft, grey, margin of scarious side concave; ligule c. 0.5 mm, white, scarious, arch higher than wide; blades 1.5-2.5 mm wide, carinate, flat to folded, grey-green, margin revolute, both sides papillose, margins and keel scabrous especially towards apex. Inflorescence 25-50 mm, of 3-7 gynecandrous spikes, overlapping or lower remote. Bracts glume-like or lowest sometimes green, narrow, much longer than its spike. Spikes 5-8.5 x 3-4 mm, sessile; female glumes 1.5-2 x 1.3-1.5 mm, cymbiform, acute, midnerve green or yellow, sides scarious; utricles 2-2.3 x 1-1.3 mm, ellipsoid to ovoid, plano-convex, rather clearly nerved, green to yellow, papillose, occasionally with a 0.1 mm stipe; beak obscure, conical, with scabrous, almost straight lateral nerves. Nut 1.3-1.6 x c. 0.9 mm, ovoid, lenticular, apiculate, light brown to brown, finely striate papillose.

Plants cespitose, in small and medium-sized clumps; rhizomes short. Culms erect, not stiff, 15–90 cm. Leaves: sheaths pale brown abaxially, inner band thin, hyaline, sometimes slightly red tinged, concave at summit; ligules slightly longer than wide; blades pale green to gray-green flat, 10–20(–30) cm × (1.5–)2–4 mm, subequal to shorter than culms, not stiff. Inflorescences 2–15 cm × 5–10 mm; proximal bracts shorter than to exceeding spikes; distal bracts usually scalelike. Spikes 4–8, gynecandrous, proximal ± remote, distal spikes approximate, sometimes flexuous, containing (5–)10–20(–30) perigynia suborbicular to oblong, 3–12 × 3–5 mm; terminal spike staminate for less than 1/2 of length, often clavate due to more conspicuous staminate part. Pistillate scales hyaline with green, 3-veined center when young, usually brownish tinged in age, broadly ovate, subequal to, not concealing perigynia, apex obtuse to acutish. Perigynia appressed-ascending, gray-green, becoming yellowish brown, obscurely many-veined, elliptic-ovate, 1.8–3 × 1.2–1.7 mm, widest near middle, membranous; beak abaxial suture inconspicuous, small marginal teeth. Achenes pale brown, oblong-obovate, 1.25–1.5 × 1–1.25 mm, dull to slightly glossy. 2n = 56.
