INFLORESCENCE Synflorescence bractiferous; clustered at the nodes; in globose clusters; dense; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters.
Fertile spikelets sessile.
FERTILE SPIKELETS Spikelets comprising 1–2 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 8 mm long; 1.5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.
GLUMES Glumes several; persistent; similar; shorter than spikelet.
FLORETS Fertile lemma ovate; 7 mm long; chartaceous; without keel. Lemma apex acute. Palea chartaceous; 4 -veined; without keels, or 2-keeled but the uppermost without keels. Palea keels ciliolate.
