Upper glume apex dentate; 2-3 -fid; muticous, or mucronate.
    Florets
    Fertile lemma lanceolate, or elliptic; 8-10 mm long; coriaceous; 5 -veined. Lemma surface pubescent. Lemma apex dentate; 2 -fid; mucronate. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
