Perennial (always ?). Stems erect, tufted, obtus-angular, slightly compressed, glabrous and smooth, 10-30(-50) cm by ½-1 mm, the base clothed with 2-3 bladeless or very short-bladed, obliquely truncate sheaths ferrugineous-membranous at the mouth. Leaves shorter than the stems, flaccid, flat, obtuse or abruptly acuminate, glabrous, scabrid on the margins in the upper part, (1½-)2-4 mm wide; ligule absent. Inflorescence simple or compound, relatively small, dense to rather loose, with 4-25 spikelets, 1-5 cm long and wide. Involucral bracts small, glume-like, or the lower 1-2 produced into a short point. Primary rays 4-6, obliquely erect but outer ones widely spreading, compressed, smooth, up to 3 cm; secondary rays very short, widely spreading. Spikelets solitary, ovoid or oblong-ovoid, terete, acute, brown, 4-8 by c. 2 mm; rachilla winged. Glumes spiral, membranous, appressed, ovate or broadly ovate, obtuse, mucronulate, slightly keeled, with prominent midnerve, glabrous, nerveless sides, and scarious, ciliate margins, 2¼-3 by c. 2 mm. Stamens 2-3; anthers oblong-linear, 1-1½ mm; connective dis-tinctly produced, setulose at the top. Style triquetrous, pyramidally thickened at the base, sparsely ciliate, hispidulous at the base, 1¼-1¾ mm; stigmas 3, about as long as or longer than the style. Nut obtusely trigonous, obovoid, shortly stipitate, um-bonulate, smooth or scaly-verruculose, purplish black, 3/5-7/10 by 2/5-½ mm; epidermal cells longi-tudinally oblong to almost isodiametric.
