Over 100 names have been proposed for species, subspecies, varieties, and other infraspecific taxa within ''Avenula'', but only one species is accepted. The others names are all regarded as synonyms of other accepted names. The only recognized species in the genus is ''Avenula pubescens'', commonly known as downy oat-grass or downy alpine oatgrass, native to Europe and Asia from Iceland and Portugal to Xinjiang, Mongolia, and Siberia. It is also naturalized in scattered locations in North America, in states as Connecticut, Delaware, Minnesota, New Jersey and Vermont, and in Canadian provinces such as Alberta, Manitoba, Ontario, Quebec, and Saskatchewan. Other genera containing species once included in ''Avenula'': ''Helictochloa'', ''Helictotrichon'' and ''Tricholemma''.

Danthonia Californica
''Danthonia californica'' is a species of grass known by the common name California oatgrass. This plant is native to two separate regions of the Americas, western North America from California to Saskatchewan, and Chile. Description ''Danthonia californica'' is a clumping erect perennial bunch grass with stems approaching a meter (3 feet) in height at maximum. The leaves are flat and short and may be hairy or hairless. The inflorescence holds one or more spikelets, each spikelet holding up to eight florets. This grass grows best in moist areas, generally in thin forests and meadows. Typical native grass associates in the far western North American coastal prairies are ''Festuca idahoensis'', '' Deschampsia caespitosa'', and ''Nassella pulchra''.C.
