The Poeae are the largest
tribe of the
grasses , with around 2,500 species in 121 genera.
[1] The tribe includes many
lawn and
pasture grasses.
Taxonomy
Two separate tribes, Poeae and Aveneae, used to be distinguished based on morphology, but phylogenetic analysis showed that they are intermingled. Poeae now includes the former Aveneae. Phylogenetic analyses identified two lineages based on
chloroplast genomes . The genera are classified in 25 subtribes.
[1]
Reticulate evolution occurred repeatedly in the tribe.
