Leaves spreading to erect, distichous, usually hairy; hairs often in two series-a dense, short, velvety layer overlain by sparser bristles to 1 mm long; blade flat or inrolled, 1–12 cm long, 2–6 mm broad; ligule ciliate to 0.5 mm long with marginal hair-tufts to 2 mm long. Inflorescence an erect, spike-like raceme 2–4 cm long. Spikelets subsessile, 4–12 per raceme, 4.0–6.0 mm long, pale green; glumes subequal, 0.5–1.8 mm long, variably covered with short, stiff hairs; lemmas generally hairy or scabrous along the 5–7 slightly raised nerves, sterile lemma from one-third to one-half length of spikelet, obtuse, dorsally rounded, upper sterile lemma obtuse to acute, sometimes shortly mucronate; fertile lemma subequal to upper sterile lemma but more strongly keeled; palea slightly shorter than fertile lemma; stamens 4.
