Rhachis narrowly winged; angular; 1 mm wide. Spikelet packing adaxial; regular; 2 -rowed. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; compressed strongly; plano-convex; cuspidate; 4-5 mm long; falling entire. Spikelet callus pilose.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; compressed strongly; plano-convex; cuspidate; 4-5 mm long; falling entire. Spikelet callus pilose.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.1-0.2 length of spikelet; hyaline; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 2 length of adjacent fertile lemma; 1 length of spikelet; membranous; without keels; 7-9 -veined. Upper glume surface pubescent; hairy below. Upper glume apex obtuse.
    Florets
    Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 7 -veined; with unevenly spaced veins (near margins); ciliate on margins; obtuse. Fertile lemma elliptic; 2-2.5 mm long; indurate; without keel. Lemma surface rugulose. Lemma margins involute. Lemma apex obtuse; mucronate. Principal lemma awn 0.5 mm long overall.
