INFLORESCENCE Inflorescence a panicle.

Panicle open.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; tip pyriform.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 1.3–1.6–2 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.

GLUMES Glumes persistent; exceeding apex of florets; similar to fertile lemma in texture (1), or firmer than fertile lemma (1). Lower glume ovate; 1 length of upper glume; membranous; 1-keeled; 1 -veined (1), or 3 -veined (1). Lower glume lateral veins absent (1), or distinct (1). Lower glume surface without pits. Lower glume apex obtuse. Upper glume ovate; 1.6–1.8–2 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex obtuse.

FLORETS Fertile lemma elliptic; hyaline (1), or membranous (1); without keel; wingless; 3 -veined. Lemma surface unwrinkled; without grooves. Lemma apex dentate; 3 -fid; truncate (1/1). Palea 1 length of lemma.
