    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 10 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 1 mm long; pubescent; obtuse, or acute.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 10 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 1 mm long; pubescent; obtuse, or acute.
    Glume
    Glumes similar; exceeding apex of florets; thinner than fertile lemma. Lower glume linear; 10 mm long; 1 length of upper glume; membranous; 1 -veined. Lower glume primary vein ciliolate. Lower glume lateral veins absent. Lower glume apex acuminate to setaceously attenuate. Upper glume linear; 10 mm long; 2 length of adjacent fertile lemma; membranous; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume apex acuminate to setaceously attenuate.
    Florets
    Fertile lemma linear; subterete; 5-6 mm long; coriaceous; without keel; 3 -veined. Lemma margins convolute; covering most of palea. Lemma apex awned; 3 -awned.
