INFLORESCENCE Inflorescence a panicle.
Panicle open; obovate; effuse; 10–16 cm long. Panicle branches capillary.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; acute; 1.5–2 mm long; falling entire; readily shedding fertile florets.
GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.66–0.8 length of spikelet; membranous; without keels; 3 -veined. Lower glume apex acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume apex acute.
FLORETS Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 5 -veined; acute. Fertile lemma oblong; dorsally compressed; 1–1.5 mm long; chartaceous; pallid; without keel. Lemma surface tuberculate (verruculose). Lemma margins involute. Lemma apex obtuse.
