INFLORESCENCE Inflorescence a panicle.

Panicle contracted; lanceolate; continuous, or interrupted; 3–20 cm long.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 3–5 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume ovate; 3–4 mm long; 0.6–0.8 length of upper glume; membranous; grey; without keels; 5–7 -veined. Lower glume surface pubescent. Lower glume apex acute. Upper glume ovate; 3.5–5.5 mm long; 2.5 length of adjacent fertile lemma; membranous; grey; without keels; 3 -veined. Upper glume surface pubescent. Upper glume apex emarginate.

FLORETS Fertile lemma oblong; 1.5–2 mm long; chartaceous; without keel; 9 -veined. Lemma surface villous; hairy below. Lemma apex dentate; 9 -fid; awned; 9 -awned. Principal lemma awn 2.5–5 mm long overall; limb ciliate. Lateral lemma awns arising on apex of lobes; subequal to principal; ciliate. Palea keels ciliolate. Apical sterile florets 2 in number; dissimilar. First apical floret male; oblong; villous. Apical sterile florets barren; rudimentary. Apical sterile lemmas awned; 9 -awned. Apical sterile lemma awns 0.7–2 mm long; ciliate.

FLOWER Lodicules 2. Anthers 3; 1–2.7 mm long.
