INFLORESCENCE Inflorescence a panicle.
Spikelets solitary, or in pairs. Fertile spikelets pedicelled; 1–2 in the cluster. Pedicels filiform.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 1.5–2 mm long; falling entire; deciduous with the pedicel.

Lower glume surface without pits. Lower glume apex acute. Upper glume ovate; 0.5 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume apex acute.
FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; membranous; 1–3 -veined; acute. Fertile lemma lanceolate; membranous; much thinner on margins; without keel; wingless; 3 -veined. Lemma surface unwrinkled; without grooves. Lemma margins ciliate. Lemma apex acute. Palea 0.5 length of lemma.
