False panicle c. 30 cm long, copious but becoming scanty in poorly grown specimens; spatheoles 2.5–5 cm long, lanceolate, glabrous; peduncles 3–5 mm long, much shorter than the spatheoles, densely barbate on one side near the apex with white bulbous-based hairs, deflexed; racemes 1.5–2 cm long, 2-awned per pair, not deflexed (instead the racemes exserted by flexion of the peduncle); raceme-bases unequal, the superior 2–2.5 mm long, subterete, thinly embellished with stiff bristles, the apex very oblique and produced into a scarious extension 0.5–0.7 mm long.
Sessile spikelets 7–9.5 mm long; callus 1.5–3 mm long, pungent; inferior glume lanceolate, pallid, glabrous or hispidulous; awn 4.5–8 cm long, the column pubescent with pallid hairs c. 0.2 mm long.
Leaf sheaths glabrous, produced at the mouth into auricles up to 10 mm long; leaf laminas up to 45 cm × 13 mm, glabrous, the longer ones narrowed at the base into a short false petiole.
Pedicelled spikelets 8–9 mm long, linear-lanceolate, glabrous, with or without a terminal bristle up to 6 mm long; callus scarcely developed; pedicel-tooth obscure.
Annual; culms up to 300 cm high, stout, erect or the inferior internodes geniculately ascending, supported by stilt roots.
Homogamous spikelets 8–9 mm long, a single pair at the base of the inferior raceme only, glabrous, awnless.
