Poeae

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.[1]

gollark: As of now, *no* reassignments could actually do it.
gollark: We have two days, I'm sure we can make negotiations for reassignments later.
gollark: They really should just be allowed to use channel names for said counters. Discord is SUCH an apioform sometimes?
gollark: I don't think so.
gollark: I... see?
