The Dryadoideae subfamily of the Rosaceae consists of four genera,[1] all of which share root nodules that host the nitrogen-fixing bacterium Frankia.[2] They are sub-shrubs, shrubs, or small trees with a base chromosome number of 9, whose fruits are either an achene or an aggregate of achenes.[1]
Taxonomic history
The subfamily has at various times been separated as its own family (Dryadaceae), or as a tribe (Dryadeae) or subtribe (Dryadinae).[3]
