Amygdaloideae

The expanded definition of the Amygdaloideae adds to these commercially important crops such as apples and pears that have pome fruit, and also important ornamental plants such as Spiraea and Aruncus that have hard dry fruits.

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.
