Inflorescence terminal, 8-70 mm long, spike-like, linear, contracted, distichous or with a few basal branches, usually secund, partly enclosed or exserted from uppermost leaf; a dehiscence node absent below flag-leaf. Spikelet to 4-10 x to 4 mm; florets 5-9; glumes shorter than spikelet, acute to acuminate, glabrous or sparsely hairy with tubercle-based hairs; lemma 4-6 mm long, obtuse to acute, glabrous or hairy, lower 1/4-1/2 of back evenly hairy, hairs club-shaped, awnless; palea acute, glabrous or hairy between keels, tufts of long marginal hairs present or absent; anthers 1.6-3.1 mm long.
Plants perennial; innovation buds extravaginal. Culms 15–60 cm high. Leaves glabrous or rarely villous; hairs simple. Inflorescences terminal, racemose or subracemose, secund, occasionally branching at the base, contracted, linear, 12–60 mm long. Spikelets 7–10 mm long, with 4–8 florets. Glumes shorter than spikelet, acute to acuminate; lower glume 4–7 mm long. Lemma 5–6 mm long, obtuse to acute, awnless, villous; hairs clavate, distributed overall. Palea elliptic to ovate, 4.5–5 mm long, glabrous between keels. Anthers 2.8–3.1 mm long. Grain 1.2–1.7 mm long.
