INFLORESCENCE Inflorescence a panicle.

Panicle open; elliptic; 23 cm long; 8 cm wide. Panicle branches capillary.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–11 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 8 mm long; 1 mm wide; breaking up at maturity; rhachilla persistent; retaining paleas.

Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 1.6 mm long; 0.75 length of adjacent fertile lemma; membranous; with hyaline margins; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex obtuse, or acute.

FLORETS Fertile lemma ovate; 2 mm long; chartaceous; mid-green, or grey; keeled; 3 -veined. Lemma apex obtuse. Palea 1.8 mm long. Apical sterile florets resembling fertile though underdeveloped.
