    Inflorescences
    Inflorescence a panicle. Panicle open; ovate; effuse; 12-25 cm long. Primary panicle branches spreading; 1 -nate; 5-10 cm long. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; glabrous.
    Spikelets
    Spikelets comprising 3-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 18-20 mm long; breaking up at maturity; disarticulating above glumes but not between florets.
    Fertile
    Spikelets comprising 3-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 18-20 mm long; breaking up at maturity; disarticulating above glumes but not between florets.
    Glume

Lower glume apex acute. Upper glume lanceolate; 4-7 mm long; 0.5-0.6 length of adjacent fertile lemma; membranous; purple; without keels; 5 -veined. Upper glume apex acute.
    Florets
    Fertile lemma elliptic; 6-11 mm long; chartaceous; without keel; 7-9 -veined. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn subapical; 3-5 mm long overall. Palea 0.66 length of lemma; 2 -veined. Palea keels ciliolate. Apical sterile florets 2-3 in number; barren; in a clump; lanceolate; 4 mm long. Apical sterile lemmas awned.
