Poaceae Barnhart. Common name: Grass Family.

Key to Poaceae

A family of about 771 genera and 12,074 species, herbs (and some shrubs and trees), cosmopolitan. Tribal classification largely follows FNA (2003a, 2007a), with some changes based on subsequent research, as for instance in the Chloridoideae (Peterson, Romaschenko, & Johnson 2010a). Key to genera adapted in large part from FNA. Subtribal classification of the Andropogoneae is from Welker et al. (2020).

Grass classification from Soreng et al. (2015).

Key advice:The key to bamboos based on Stapleton (2007). Other genera are grown and may be expected to persist and vegetatively spread or potentially truly naturalize in our area.
