INFLORESCENCE Inflorescence a panicle.

Panicle open; 6–10 cm long.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 2–12 mm long; ciliate.

FERTILE SPIKELETS Spikelets comprising 5–14 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 5–15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes clavate; 3–5 mm long; pubescent.

FLORETS Fertile lemma ovate; 7–8 mm long; chartaceous; without keel. Lemma surface pilose; inner surface pilose. Lemma margins ciliolate. Lemma apex acuminate; mucronate. Palea 8–9 -veined. Palea surface pilose; hairy on margins. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.
