    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 7-10(-14) mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 1 mm long; pilose; obtuse.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 5.5-10 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume primary vein scaberulous. Lower glume apex setaceously attenuate. Upper glume lanceolate; 5.5-10 mm long; 0.7-0.8 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex dentate; 2 -fid; mucronate.
    Florets
    Fertile lemma elliptic; subterete; 7-10(-14) mm long; coriaceous; keeled; 3 -veined. Lemma margins convolute; covering most of palea. Lemma apex acute; awned; 1 -awned, or 3 -awned. Principal lemma awn curved, or 3-branched; with (7.5-)15-25 mm long limb; with twisted column; persistent. Column of lemma awn 3.5-10 mm long. Lateral lemma awns 0-15 mm long; shorter than principal.
