INFLORESCENCE Inflorescence a panicle.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 3–5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 2–2.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite. Floret callus pubescent.
GLUMES Glumes persistent; reaching apex of florets. Lower glume lanceolate; 0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface without pits. Lower glume apex acuminate. Upper glume lanceolate; 2 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume apex acuminate.
FLORETS Fertile lemma oblong; membranous; keeled; wingless; 3 -veined. Lemma surface unwrinkled; without grooves. Lemma margins ciliate. Lemma apex dentate; 2 -fid; truncate; awned; 1 -awned. Principal lemma awn from a sinus; curved. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 2; fleshy. Anthers 3.
