Description:	A compact caespitose often stoloniferous perennial, usually densely glandular-pubescent all over. Culms 5-15 (rarely to 40) cm. tall, 2-5-noded, geniculately ascending, sometimes decumbent, often with a bulbous thickening at the base, simple or branched, rather slender, asperulous. Leaves mostly confined to the base, forming dense tufts; sheaths tight at first later somewhat loose, finely to coarsely striate, the oldest long-persistent and splitting into fibres which form dense cushions at the base of the culm. Leaf-laminae 2.5-7.5(12) x 0.3-0.5 cm., filiform, almost always convolute, tapering to a very fine point, flexible, asperulous. Panicle 1.5-5(7.5) cm. long, spike-like, narrowly cylindrical or rarely ovate-oblong in outline, rather dense, light to dark grey. Spikelets 3-5.5 mm. long, 3-flowered (see note below), crowded. Glumes subequal, oblong, scantily pilose, with the apex obtuse to slightly emarginate, light to dark grey; the inferior 2.3-5 mm. long, 3-7-nerved; the superior 2.8-5.5 mm. long, 3-5-nerved. Fertile lemma (the inferior) 1.5-2 mm. long (excluding the awns), dorsally shortly villous; awns 2-4 mm. long, shortly plumose to or beyond the middle. Anthers 0.3-0.5 (rarely 0.7) mm. long. Caryopsis c. 1 mm. long.
