    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3.5-6 mm long; falling entire; deciduous with accessory branch structures; readily shedding fertile florets.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate, or oblong; 1-3 mm long; 0.33-0.5 length of spikelet; hyaline; without keels; 0-1 -veined. Lower glume lateral veins absent. Lower glume surface pubescent; hairy below. Lower glume apex emarginate, or obtuse, or acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 5-7 -veined. Upper glume surface pubescent; hairy below. Upper glume margins eciliate, or ciliate. Upper glume apex acute; muticous, or mucronate.
    Florets
    Basal sterile florets male, or barren; with palea, or without significant palea. Lemma of lower sterile floret similar to upper glume; oblong; 1 length of spikelet; membranous; 5 -veined; puberulous; dentate; 3 -fid. Fertile lemma lanceolate; 2.5-3 mm long; coriaceous; shiny; without keel; 5 -veined. Lemma margins flat. Lemma apex obtuse. Palea coriaceous.
