    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 9-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; pubescent; acute.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 9-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; pubescent; acute.
    Glume
    Glumes persistent; similar; shorter than spikelet, or reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 4.5-12 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein smooth to scabrous. Lower glume lateral veins absent. Lower glume apex acute, or acuminate. Upper glume lanceolate; 4.5-12 mm long; 0.5-1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume surface smooth to scabrous. Upper glume apex acute, or acuminate.
    Florets
    Fertile lemma lanceolate; subterete; 9-10.5 mm long; coriaceous; pallid, or light brown; without keel; 3 -veined. Lemma margins convolute; covering most of palea; scaberulous. Lemma apex acute; awned; 3 -awned. Principal lemma awn with 12.5-25 mm long limb; without a column; persistent. Lateral lemma awns 11-23 mm long; subequal to principal. Palea 0.2 length of lemma; without keels.
