{{main|List of Rosaceae genera}}

Identified clades include:
* Subfamily [[Rosoideae]]: Traditionally composed of those genera bearing [[fruit#Aggregate fruit|aggregate fruits]] that are made up of small achenes or [[drupelet]]s, and often the fleshy part of the fruit (e.g. [[strawberry]]) is the [[Receptacle (botany)|receptacle]] or the stalk bearing the carpels. The circumscription is now narrowed (excluding, for example, the Dryadoideae), but it still remains a diverse group containing five or six tribes and 20 or more genera, including rose, ''[[Rubus]]'' (blackberry, raspberry), ''[[Fragaria]]'' (strawberry), ''[[Potentilla]]'', and ''[[Geum]]''.
* Subfamily [[Amygdaloideae]]: Within this group remains an identified clade with a pome fruit, traditionally known as subfamily Maloideae (or Pyroideae) which included genera such as apple, ''[[Cotoneaster]]'', and ''[[Crataegus]]'' (hawthorn). To separate it at the subfamily level would leave the remaining genera as a [[paraphyletic]] group, so it has been expanded to include the former Spiraeoideae and Amygdaloideae.<ref name="Potter" /> The subfamily has sometimes been referred to by the name "Spiraeoideae", but this is not permitted by the [[International Code of Nomenclature for algae, fungi, and plants]].
* Subfamily [[Dryadoideae]]: Fruits are achenes with hairy styles, and includes five genera (''[[Dryas (plant)|Dryas]]'', ''[[Cercocarpus]]'', ''[[Chamaebatia]]'', ''[[Cowania (plant)|Cowania]]'', and ''[[Purshia]]''), most species of which form [[root nodule]]s which host nitrogen-fixing bacteria from the genus ''[[Frankia]]''.
