    Inflorescences
    Inflorescence composed of racemes. Racemes (1-)2(-3); single, or paired, or digitate; unilateral; 3-8 cm long. Rhachis narrowly winged; angular; 1 mm wide; pubescent on margins. Spikelets appressed; in pairs. Fertile spikelets pedicelled; 2 in the cluster.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 2.5-3.5 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 2.5-3.5 mm long; falling entire.
    Glume
    Glumes one the lower absent or obscure; shorter than spikelet; thinner than fertile lemma. Upper glume ovate; 0.5-1.5 mm long; 0.2-0.4 length of spikelet; membranous; without keels; 0-1 -veined. Upper glume primary vein absent, or distinct. Upper glume lateral veins absent. Upper glume apex obtuse, or acute; muticous, or awned; 1 -awned.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; 1 length of spikelet; membranous; 5 -veined; ribbed; convex across back; scabrous; rough on veins; acute; awned. Awn of lower sterile floret 10-25 mm long. Fertile lemma elliptic; 2.5-3.5 mm long; chartaceous; much thinner on margins; dark brown; without keel. Lemma margins flat; covering most of palea. Lemma apex acute. Palea chartaceous.
