INFLORESCENCE Inflorescence a panicle.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
FERTILE SPIKELETS Spikelets comprising 3–7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 7.47–10.8 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 lanceolate; 0.5–0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface without pits. Lower glume apex acute. Upper glume oblong; 1–1.3 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume surface scabrous. Upper glume apex acute.
FLORETS Fertile lemma oblong; chartaceous; keeled; wingless; 5 -veined. Lemma lateral veins prominent. Lemma surface scabrous; unwrinkled; without grooves. Lemma apex erose; truncate. Palea 1 length of lemma; 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 2; membranous. Anthers 3. Ovary pubescent on apex.
