INFLORESCENCE Inflorescence a panicle.
Panicle spiciform; linear; 15–30 cm long; 0.5–0.8 cm wide. Panicle axis scabrous.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels scabrous.
FERTILE SPIKELETS Spikelets comprising 8–10 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 10 mm long; breaking up at maturity; rhachilla persistent; retaining paleas. Rhachilla internodes obscured by lemmas.
GLUMES Glumes deciduous; similar; shorter than spikelet. Lower glume lanceolate; 5 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex attenuate. Upper glume lanceolate; 5 mm long; 1.7 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins distinct. Upper glume apex attenuate.
FLORETS Fertile lemma ovate; 3 mm long; chartaceous; keeled; 3 -veined. Lemma midvein scaberulous. Lemma lateral veins obscure. Lemma apex acute. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
