INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 5–6 cm long.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–5 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 4.5–5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1 mm long; pilose. Floret callus woolly.

Lower glume surface scabrous; rough above. Lower glume apex acute. Upper glume lanceolate; 3.5 mm long; 1 length of adjacent fertile lemma; membranous; with hyaline margins; 1-keeled; 3 -veined. Upper glume surface scabrous; rough above. Upper glume apex acute.

FLORETS Fertile lemma elliptic; 3.5 mm long; membranous; keeled; 5 -veined. Lemma midvein pubescent. Lemma margins pubescent. Lemma apex acute. Palea 1 length of lemma. Palea keels ciliolate. Palea surface puberulous; hairy on flanks; hairy below. Apical sterile florets resembling fertile though underdeveloped.
