INFLORESCENCE Inflorescence a panicle.

Panicle open; lanceolate; 5–7 cm long. Primary panicle branches spreading. Panicle branches capillary; pilose.

Spikelets solitary. Fertile spikelets pedicelled.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; lanceolate, or ovate; 1.5 mm long; 1 length of spikelet; membranous; 3 -veined; acute.
