    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; multilateral; 3-7 cm long. Rhachis angular. Spikelet packing abaxial; irregular. Spikelets ascending; solitary. Fertile spikelets pedicelled. Pedicels linear.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3.2-4 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3.2-4 mm long; falling entire.
    Glume
    Glumes similar; shorter than spikelet; thinner than fertile lemma. Lower glume orbicular; 0.2-0.5 mm long; 0.5-1 length of upper glume; 0.1 length of spikelet; hyaline; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex truncate, or obtuse. Upper glume orbicular; 0.4-0.6 mm long; 0.1 length of spikelet; hyaline; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex truncate, or obtuse.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; 1 length of spikelet; membranous; 5 -veined; scabrous; rough on veins; acuminate; awned. Awn of lower sterile floret 1-5 mm long. Fertile lemma elliptic; 3-3.6 mm long; membranous; without keel; 5 -veined. Lemma margins flat; covering most of palea. Lemma apex acute; mucronate. Palea 0.5 length of lemma; hyaline; without keels.
