Inflorescence varying in number of spikelets and degree of branching, from a terminal, much-branched ± umbellate panicle with several leafy bracts, to an apparently lateral single spikelet or small cluster of spikelets, with subterete green bract appearing as a prolongation of the stem. Spikelets usually many-flowered. Glumes spirally imbricate round rhachilla, all floriferous or lower 1- (2) empty; flowers hermaphrodite. Hypogynous bristles c. 6, or often 0. Stamens 3 or fewer.
