Tribe:	Danthonieae; Zotov

Danthonioideae is a mainly southern hemisphere subfamily of grasses, containing the single tribe Danthonieae and three unplaced genera, with altogether roughly 300 species.^[1] It includes herbaceous to partially woody perennial or annual (less common) grasses that grow in open grasslands, shrublands, and woodlands.^[2] It belongs to the PACMAD clade of grasses, but unlike some other lineages in that clade, grasses in the Danthonioideae exclusively use the C₃ photosynthetic pathway.^[3] Its sister group is the subfamily Chloridoideae.^[3]

There are 20 genera, 17 of which are placed in tribe Danthonieae, while three are as yet unplaced (incertae sedis).^[1] The relationships within the group are complicated; conflicting phylogenetic evidence from nuclear and chloroplast DNA suggests that hybridisation events played an important role in the Danthonioideae.^[4]

Alloeochaete, Danthonidium, Phaenanthoecium
