Tufted perennial to 400 mm high; stolons absent. Leaf blade to 250 x 0.5-4.0 mm, usually glabrous on limestone and hairy elsewhere, hairs tubercle-based; sheath mouth with bristles. Inflorescence a sparse contracted panicle, 10-50(-70) mm long, ovate or linear; a dehiscence node absent below flag-leaf. Spikelet 3-5 x to 1.5 mm; florets 2-3(-4), not distichous; glumes usually longer than spikelet, acute to shortly acuminate, awned, scaberulous, tubercle-based hairs 1.0-1.5 mm long; lemma acuminate, awnless, keels glabrous, sub-marginal hairs in tufts, hairs acute 0.3-0.5 mm long, rarely hairs sparsely scattered; palea acute, hairy between keels, sometimes margins with long hairs; anthers 1.5-2.0 mm long.
Perennial, up to 400 mm tall. Leaves linear, glabrous or hairy; ligule a fringe of hairs. Inflorescence a sparse contracted panicle. Spikelets 3-5 mm long, 2-or 3-flowered; glumes usually longer than spikelet, densely covered with long, bristly, tubercle-based hairs, minutely scabrid, 3-7-nerved; lemmas entire, acute to acuminate, with 2 submarginal tufts of hair, rarely hairs scattered on the back; anthers 1.5-2 mm long.
