The subfamily Spiraeoideae was traditionally a subfamily of flowering plants within family Rosaceae. The taxonomy of this subfamily has changed several times in the last century as more detailed studies have been carried out. Spiraeoideae as defined before 2007 is paraphyletic, leading some authors to define a broader subfamily which includes the Spiraeoideae as well as the Maleae (plants such as pears and apples whose fruits are pomes), and the Amygdaloideae (including almonds and plums, whose fruits are drupes). Such an expanded subfamily is to be called Amygdaloideae under the International Code of Nomenclature for algae, fungi, and plants.
