The subfamily Dryadoideae consists of four genera in the family Rosaceae,[1] all of which contain representative species with root nodules that host the nitrogen-fixing bacterium Frankia.[2] They are subshrubs, shrubs, or small trees with a base chromosome number of 9, whose fruits are either an achene or an aggregate of achenes.[1] It includes five genera (Dryas, Cercocarpus, Chamaebatia, Cowania, and Purshia), all of which except the first only occur in North America.
