INFLORESCENCE Inflorescence a panicle, or composed of racemes.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 4–8 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 12–25 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite. Floret callus bearded.
GLUMES Glumes persistent; reaching apex of florets, or exceeding apex of florets; thinner than fertile lemma; gaping. Lower glume lanceolate; 0.8 length of upper glume; chartaceous; 1-keeled; 5–7 -veined. Lower glume surface without pits. Lower glume apex attenuate. Upper glume lanceolate; 2 length of adjacent fertile lemma; chartaceous; with hyaline margins; 1-keeled; 7–9 -veined. Upper glume apex setaceously attenuate.
FLORETS Fertile lemma lanceolate; coriaceous; without keel; wingless; 7–9 -veined. Lemma surface unwrinkled; without grooves; pilose. Lemma apex lobed; 2 -fid; incised 0.3 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate. Palea 0.6 length of lemma; 2 -veined. Palea keels winged. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 2; membranous; obtuse. Anthers 3. Stigmas 3. Ovary pubescent all over.
