FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate (1), or elliptic (5); dorsally compressed; 2.2-3.537-6.5 mm long; falling entire. GLUMES Glumes reaching apex of florets (1), or exceeding apex of florets (5); thinner than fertile lemma. Lower glume ovate (4), or oblate (2); hyaline (2), or membranous (4); without keels; 0-1 -veined (3). Lower glume lateral veins absent. Lower glume apex obtuse (1), or acute (5), or acuminate (1). Upper glume lanceolate (1), or elliptic (4), or ovate (1); 1-1.066-1.3 length of adjacent fertile lemma; membranous (2), or herbaceous (4); without keels; 5 -veined. Upper glume surface smooth, or asperulous (2). Upper glume apex obtuse (1), or acute (5). FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic (4), or ovate (2); membranous (2), or herbaceous (4); 5 -veined (5/5); obtuse (1), or acute (5). Fertile lemma elliptic (4), or oblong (2); dorsally compressed; coriaceous; without keel; 5 -veined (5/5). Lemma lateral veins obscure (5/5). Lemma surface pubescent. Lemma margins involute.
