INFLORESCENCE Inflorescence a panicle.

Panicle contracted.

Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels linear.

FERTILE SPIKELETS Spikelets comprising 5–13 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 5–13 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.

GLUMES Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.6–1 length of upper glume; membranous; 1-keeled; 3–5 -veined. Lower glume surface without pits. Lower glume apex obtuse. Upper glume ovate; 0.6–1.1 length of adjacent fertile lemma; membranous; 1-keeled; 3–5 -veined. Upper glume apex obtuse.

FLORETS Fertile lemma elliptic; linear in profile; chartaceous; much thinner on margins; keeled; wingless; 5–11 -veined. Lemma lateral veins ribbed. Lemma surface unwrinkled; without grooves; pilose; hairy on veins. Lemma apex emarginate, or obtuse. Palea 1 length of lemma; 2 -veined. Palea keels eciliate, or ciliate. Apical sterile florets resembling fertile though underdeveloped.
