INFLORESCENCE Inflorescence composed of racemes.
Racemes 5–8; borne along a central axis; unilateral; 3–6 cm long. Central inflorescence axis 8 cm long. Rhachis wingless. Spikelet packing abaxial; 4 -rowed. Raceme-bases brief; pilose.
Spikelets in pairs. Fertile spikelets pedicelled. Pedicels unequal.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; plano-convex; acute; 2–2.8 mm long; falling entire.
GLUMES Glumes one the lower absent or obscure; reaching apex of florets; thinner than fertile lemma. Upper glume ovate; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume margins ciliate. Upper glume apex obtuse.
FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; membranous; 5 -veined; glabrous, or puberulous; ciliate on margins; obtuse. Fertile lemma elliptic, or ovate; 2–2.8 mm long; indurate; pallid; without keel. Lemma margins involute. Palea involute; indurate.
