INFLORESCENCE Inflorescence a panicle.

Panicle open; linear, or oblong; 3–4 cm long; bearing few spikelets. Primary panicle branches indistinct the panicle almost racemose.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 5–7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 10–20 mm long; 3–5 mm wide; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; dissimilar; shorter than spikelet. Lower glume lanceolate; 4–5 mm long; 0.8–0.9 length of upper glume; chartaceous; without keels; 3 -veined. Lower glume apex obtuse; mucronate. Upper glume lanceolate; 5–6(–10) mm long; 0.7–0.8 length of adjacent fertile lemma; chartaceous; without keels; 5–7 -veined. Upper glume apex obtuse; mucronate.

FLORETS Fertile florets with the lowest dissimilar. Lowest fertile lemma awned (1-awned). Fertile lemma elliptic; 7–8 mm long; 3–4 mm wide; coriaceous; without keel. Lemma apex dentate; 2 -fid; awned; 3 -awned. Principal lemma awn subapical; 2–10 mm long overall. Lateral lemma awns arising on apex of lobes; 3–4 mm long. Palea 1 length of lemma. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Anthers 3; 1 mm long. Ovary with a fleshy appendage above style insertion.
