INFLORESCENCE Inflorescence a panicle.
Panicle open; lanceolate; 15–26 cm long. Panicle branches smooth.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 5–10 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 8–14 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 1.3–1.7 mm long; 0.75 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Upper glume lanceolate; 1.7–2.3 mm long; 0.66 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume lateral veins absent.
FLORETS Fertile lemma ovate; 2.6–3.3 mm long; membranous; much thinner above; without keel. Lemma lateral veins with distinct primaries but obscure intermediates. Lemma surface asperulous. Lemma apex attenuate. Palea 1 length of lemma; 2 -veined. Palea keels winged; narrowly winged. Apical sterile florets resembling fertile though underdeveloped.
