Inflorenscence of a grass with long awns on a white background

The true grasses (Poaceae) are one of the largest plant families, with over 11,000 species and roughly 800 genera. They contain, among others, the cereal crop species and other plants of economic importance, such as the bamboos.

The deeper relationships in the family have been resolved by recent phylogenetic work;[1] it is now divided in twelve subfamilies. Anomochlooideae, Pharoideae and Puelioideae are early diverging lineages containing only a few species. Most of the diversity falls into the two big BEP and PACMAD clades, which each contain roughly halve of the family's species. A major ecological feature of many species, found only in the PACMAD clade, is the evolution of C4 photosynthesis.

There has been substantial revision of the taxonomy at species and genus level over the last years. The list of genera below is therefore indicative.
