Upper glume ovate; 3-4 mm long; 0.4-0.5 length of adjacent fertile lemma; herbaceous; without keels; 5-7 -veined. Upper glume apex acute.
    Florets
    Fertile florets divergent. Fertile lemma obovate; 7-10 mm long; herbaceous; without keel; 11 -veined. Lemma surface pubescent; hairy all along. Lemma apex acute. Palea 1 length of lemma; 6 -veined. Palea keels winged; narrowly winged; ciliolate. Apical sterile florets resembling fertile though underdeveloped.
