Sheaths pale to greyish, glabrous, sometimes with scattered long hairs; collar hairs 1- 3 mm long; ligule c. 0.3 mm long; lamina to 15—(22) cm long, stiff, inrolled with scabrous margins, glabrous, or with scattered long hairs. Culms up to 45 cm long, glabrous, minutely scabrous below inflorescence. Panicle strict, up to 6.5 cm long, shortly branched below, with few to many spikelets on short pedicels; rhachis and pedicels closely short-scabrous, with numerous minute hairs interspersed, longer hairs below spikelets and at branch axils.
