Most of the diversity falls into the two big BOP and PACMAD clades, which each contain roughly half of the family's species. C₄ lineages have only evolved in the PACMAD clade, whereas many lineages in the BOP clade have evolved adaptations to cold climate. While the higher-level classification of the grasses is now relatively well understood, taxonomic efforts continue at the species and genera level, and with continuing phylogenetic research, a number of names is likely to change. The list of genera below is therefore likely to evolve with further study.
