Chloridoideae is one of the largest subfamilies of grasses, with roughly 130 genera and 1,600 species, mainly found in arid tropical or subtropical grasslands. Within the PACMAD clade, their sister group are the Danthonioideae. The subfamily includes widespread weeds such as Bermuda grass (Cynodon dactylon) or goosegrass (Eleusine indica), but also millet species grown in some tropical regions, namely finger millet (Eleusine coracana) and teff (Eragrostis tef).
