INFLORESCENCE Inflorescence a panicle.
Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels filiform.
FERTILE SPIKELETS Spikelets comprising 4–8 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 6–10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
GLUMES Glumes shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 1 length of upper glume; membranous; without keels; 3 -veined. Lower glume surface without pits. Lower glume apex acute. Upper glume ovate; 0.75 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex acute.
FLORETS Fertile lemma ovate; laterally compressed; cartilaginous; without keel; wingless; 5–7 -veined. Lemma surface unwrinkled; without grooves. Lemma apex acute. Palea 1 length of lemma; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
