Lower glume lateral veins absent (2), or distinct (1). Lower glume apex obtuse (1), or acute; muticous (2), or mucronate (1). Upper glume lanceolate (1), or ovate (2); 0.5-0.825-1 length of adjacent fertile lemma; membranous (1), or scarious (2); with undifferentiated margins (1), or hyaline margins (2); without keels (1), or 1-keeled (2); wingless (1), or winged on keel (2); 1 -veined (2), or 5 -veined (1). Upper glume apex obtuse (1), or acute; muticous (2), or mucronate (1).
    Florets
    Fertile lemma elliptic (1), or ovate (2); membranous (1), or chartaceous (2), or coriaceous (1); of similar consistency on margins (1), or much thinner on margins (2); without keel; 5 -veined, or 6-7 -veined (2), or 8-9 -veined (1). Lemma surface smooth, or scabrous (1); glabrous (2), or pubescent (1), or pilose (1); with simple hairs (1/2), or capitate hairs (1/2). Lemma apex entire, or dentate (1); 2 -fid (1/1); emarginate (1), or obtuse (1), or acute (1); muticous (1), or mucronate (2), or awned (1); 1 -awned (1/1). Principal lemma awn apical (2), or from a sinus (1). Palea 0.9-0.95-1 length of lemma; 2 -veined (2/2). Palea keels smooth (2), or scaberulous (1); eciliate (2), or ciliolate (1). Apical sterile florets resembling fertile though underdeveloped (2/2).
