    Fertile
    Spikelets comprising 4-9 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 12-17 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 12-17 mm long; 1 length of upper glume; membranous; without keels; 3-5 -veined. Lower glume apex acuminate. Upper glume lanceolate; 12-17 mm long; 3 length of adjacent fertile lemma; membranous; without keels; 3-5 -veined. Upper glume apex acuminate.
