Cogongrass Imperata cylindrica, copyright Keisotyo.

Belongs within: Panicoideae.
Contains: Sorghum, Dichanthium, Saccharum, Ischaemum, Pollinia, Andropogon, Chrysopogon, Cymbopogon.

The Andropogoneae are a tribe of C4 grasses characterised by the possession of paired spikelets with bracts present outside the spikelets (Grass Phylogeny Working Group 2001). This tribe includes a number of economically significant crops such as maize Zea mays and sugarcane Saccharum officinarum. Miscanthus species are grown as ornamentals and for biofuel. Cogongrass Imperata cylindrica is a dominant plant species in disturbed habitats in many warmer regions of the Old World and has also become an invasive species outside its native range.

Members of the subgroup Mayadeae bear unisexual spikelets with male spikelets usually paniculate and female spikelets spicate at the base of the males or borne in a separate inflorescence. The Rottboellieae bear spikelets that lack awns and are usually present in pairs, with one member of a pair being sessile and fertile and the other pedicellate and barren. Awns are present in the Euandropogoneae in which spikelets are usually borne in pairs or groups of three (Bentham 1878).
