Fabaceae is the systematic name of the plant family that is commonly known as the Pea family. It consists of three subgroups: Caesalpinioideae, Mimosoideae and Papilionoideae (or better Faboideae). In modern systems like APG II this family Fabaceae is closely related to Quillajaceae, Polygalaceae or milkworts (including the families Diclidantheraceae, Moutabeaceae, and Xanthophyllaceae), and Surianaceae.
