Cynodonteae is a large tribe of grasses in the subfamily Chloridoideae, with over 800 species. Like most of the subfamily, species in the tribe are adapted to warm, arid climates and use the C4 photosynthetic pathway. Some species, such as Bermuda grass (Cynodon dactylon) or goosegrass (Eleusine indica), are widespread weeds, introduced in many countries. Most of the 93 genera are classified in one of 18 subtribes, but some are still unplaced (incertae sedis) within the tribe.
