Lower glume surface smooth, or scabrous (1), or tuberculate (1); glabrous, or hispid (2). Lower glume apex obtuse (1), or acute (5), or cuspidate (1); muticous, or mucronate (2). Upper glume oblong (4), or ovate (2); membranous; without keels; 5 -veined (4), or 6 -veined (3), or 7 -veined (5). Upper glume lateral veins ribbed. Upper glume surface smooth, or asperulous (2), or tuberculate (1); glabrous (5), or pubescent (1), or hispid (2); with simple hairs (1/3), or tubercle-based hairs (2/3). Upper glume apex acute (1), or acuminate (4), or laterally pinched (1); muticous (5), or mucronate (1).
    Florets
    Basal sterile florets male, or barren (1); with palea. Lemma of lower sterile floret oblong (2), or ovate (4); scarious; 5 -veined, or 6-7 -veined (1); sulcate; obtuse (1), or acute (4), or acuminate (1). Palea of lower sterile floret wingless (4), or winged on keels (2). Fertile lemma elliptic (5), or orbicular (1); dorsally compressed; not gibbous (5), or gibbous (1); indurate; without keel; 3 -veined (1/1). Lemma surface smooth (4), or granulose (2); unwrinkled (4), or rugulose (1), or rugose (1). Lemma margins involute. Lemma apex acute (4), or acuminate (1), or apiculate (2). Palea indurate.
