INFLORESCENCE Inflorescence a panicle.

Panicle contracted; lanceolate; 12–15 cm long.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2–3 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 13–18 mm long; 5–7 mm wide; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pilose.

Lower glume apex acuminate. Upper glume lanceolate; 13–18 mm long; 1.5 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex acuminate.

FLORETS Fertile lemma oblong; 9–10 mm long; chartaceous; without keel; 9 -veined. Lemma surface pubescent; hairy below; with a transverse row of hair tufts; bearing 6 hair tufts in all. Lemma hairs 5–7 mm long. Lemma apex lobed; 2 -fid; incised 0.5 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; simple at base; 15–18 mm long overall; with twisted column. Palea surface pilose; hairy on flanks. Apical sterile florets resembling fertile though underdeveloped.
