INFLORESCENCE Inflorescence a panicle.

Panicle contracted, or spiciform; linear, or lanceolate; 3–10 cm long; 1.5–2 cm wide.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5.5–11.5 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 lanceolate, or ovate; 4–10 mm long; 0.6–0.9 length of upper glume; membranous; grey; without keels; 5–9 -veined. Lower glume surface pubescent. Lower glume apex acute. Upper glume lanceolate, or ovate; 5.5–11.5 mm long; 2–4 length of adjacent fertile lemma; membranous; grey; without keels; 5–9 -veined. Upper glume surface pubescent. Upper glume apex acute.

FLORETS Fertile lemma oblong; 1.5–3 mm long; chartaceous; without keel; 9 -veined. Lemma surface villous; hairy below. Lemma apex dentate; 9 -fid; awned; 9 -awned. Principal lemma awn 5–10 mm long overall; limb ciliate; glabrescent towards tip. 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; in a clump; rudimentary. Apical sterile lemmas awned; 9 -awned. Apical sterile lemma awns 4–7 mm long; ciliate.

FLOWER Lodicules 2. Anthers 3; 0.5–1.4 mm long.
