Danthonia Explained

Danthonia is a genus of Eurasian, North African, and American plants in the grass family.^[1] 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.^{[2] [3] [4] [5]} Australian species have since been reclassified into the genus Rytidosperma.^[6]
