INFLORESCENCE Inflorescence a panicle.

Panicle open.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.

FERTILE SPIKELETS Spikelets comprising 4–7 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 6–10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; pubescent. Floret callus evident; pilose.

GLUMES Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 0.5 length of upper glume; hyaline; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume surface without pits. Lower glume apex acute. Upper glume lanceolate; 0.5–0.6 length of adjacent fertile lemma; hyaline; without keels; 0–1 -veined. Upper glume apex acute.

FLORETS Fertile lemma oblong; membranous; without keel; wingless; 1 -veined. Lemma surface unwrinkled; without grooves; pilose. Lemma apex lobed; 2 -fid; incised 0.25 of lemma length; awned; 1 -awned. Principal lemma awn curved. Palea 0.8 length of lemma; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Anthers 3.
