Poaceae, also known as the true grasses, is the fourth largest plant family in the world with around 12,000 species and roughly 800 genera.<ref name="SorengPeterson2015"/><ref>Template:Cite web</ref> They contain, among others, the cereal crop species and other plants of economic importance, such as the bamboos, and several important weeds.

Grasses probably originated in the understory of tropical rainforests in the Late Cretaceous, but have since come to occupy a wide range of different habitats.<ref name="EdwardsSmith2010">Template:Cite journal Template:Open access</ref><ref name="ChristinSpriggs2013">Template:Cite journal Template:Open access</ref> Notably, they are the dominant species in grasslands, open habitats that cover around one fifth of the earth's terrestrial surface.<ref name="EdwardsSmith2010"/> The C₄ photosynthetic pathway has evolved at least 22 times independently in the grasses; C₄ species are more competitive than C₃ plants in open habitats with high light intensity and warm temperatures.<ref name="GWPGII"/>

The deeper relationships in the family have been resolved by recent molecular phylogenetic work.<ref name="GWPGII">Template:Cite journal Template:Open access</ref> This has been translated into a modern classification which divides the grasses into twelve subfamilies and a number of tribes, with large tribes further divided into subtribes.<ref name="SorengPeterson2015">Template:Cite journal Template:Open access</ref>

Anomochlooideae, Pharoideae and Puelioideae are early diverging lineages containing only a few species. 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.<ref name=VorontsovaSimons2012>Template:Cite journal</ref> The list of genera below is therefore likely to evolve with further study.
