Densely caespitose perennial without rhizomes or stolons; culms up to 120 cm tall, erect, unbranched, glabrous at the nodes, densely velutinous to glabrescent or rarely glabrous on the internodes, eglandular; basal leaf sheaths densely woolly-tomentose below, chartaceous, terete, eglandular, disintegrating into persistent fibres; ligule a line of hairs; leaf laminas 15–50 cm × 2–8(10) mm, linear, flat or becoming involute when dry, scaberulous to velutinous, rarely smooth and glabrous, glaucous to bright green.
Panicle 15–50(70) cm long, broadly linear to lanceolate, diffuse or contracted, the spikelets evenly distributed, the branches and, where present, the branchlets stiff and straight, clearly demarcated from the slender flexuous pedicels, these 3–6(10) mm long, the primary branches not or scarcely in whorls, usually terminating in a slender bristle, often with long silky hairs in the axils, eglandular.
Caryopsis 0.6–0.7 mm long, elliptic.
