    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 8.5-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; pubescent; acute.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 3.5-7 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex cuspidate. Upper glume lanceolate; 3.5-7 mm long; 0.4-0.6 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex emarginate, or obtuse.
    Florets
