Upper glume lateral veins without ribs (1), or ribbed (4). Upper glume surface smooth (3), or asperulous (1), or scabrous (1). Upper glume apex acute.
    Florets
    Fertile lemma elliptic (1), or oblong (3), or ovate (1); membranous (4), or chartaceous (1); of similar consistency above (1), or much thinner above (4); of similar consistency on margins (1), or much thinner on margins (4); without keel; 7-8 -veined (2), or 9 -veined. Lemma surface glabrous (1), or pubescent (2), or pilose (3); without hair tufts (4), or with a transverse fringe of hair (1). Lemma margins eciliate (3), or ciliate (2).

Palea surface glabrous (2), or pubescent (1), or pilose (2). Apical sterile florets resembling fertile though underdeveloped.
