Danthonia is a genus of Eurasian, North African, and American plants in the grass family.[3] Members of this genus are sometimes referred to as oatgrass, but that common name is not restricted to this genus. Other common names include heathgrass and wallaby grass.[4][5][6][7][8][9][10]Australian species have since been reclassified into the genus Rytidosperma.[11]
A number of species which were formerly classified under Danthonia are now included in Amphibromus, Astrebla, Chionochloa, Joycea, Karroochloa, Monachather, Merxmuellera, Notodanthonia, Plinthanthesis, Rytidosperma or Schismus.
