Perennial, 15-35 cm high, producing numerous ovoid shining tunicated bulbils at the ends of capillary rhizomes, the latter very soon disintegrating; stems slender, triquetrous; leaves numerous, almost setaceous, about as long as the stem.
Inflorescence of rather few spikelets arranged in a simple or compound spike or short corymb, with the rays and bracts distant from one another, one or more of the lower bracts longer than the inflorescence; spikelets reddish to pallid, linear or somewhat lanceolate, 10-15 (rarely to 30) mm long, 1.5-2 mm wide, 10-28-flowered; rhachilla broadly winged; glumes not prominently keeled, several-nerved, c. 5 mm long; style 3-branched.
Nut oblong-cuneate to obovoid-ellipsoid, 1.3-1.5 x c. 0.8 mm, trigonous with concave or convex sides, grey-brown-red, with a whitish transparent very faint reticulate-papillose layer; tip a small pyramidal point at the style base; less than one-third the length of the glume.
