Leaf-blades slightly biconvex with central groove on each face, shorter than culms, 0.5–2.0 mm wide; sheaths yellow-brown to reddish, not viscid, ± shining. Inflorescence ± ovate, of several small clusters of spikelets with rachis usually strongly flexuose (rarely scarcely so), 0.8–4 cm long, 0.5–1 cm diam.; involucral bract shorter than to longer than inflorescence. Spikelets few, 5–8 mm long; glumes 5–7, red-brown with straw-coloured patches to grey-brown, the 3 or 4 lowest empty, much shorter than fertile glumes, obtuse, mucronate, glabrous; fertile glumes 4–5 mm long, acute, slightly scabrous; hypogynous scales 6, whitish, from one-third to two-thirds length of nut. Nut ellipsoid to ovoid, grey-green, ± smooth, shining, 2.0–2.7 mm long, c. 1.5 mm diam. Flowers spring–summer.
