Hippocastanoideae is a subfamily of flowering plants in the soapberry family Sapindaceae.[1] The group was formerly treated as the separate families Aceraceae and Hippocastanaceae. Molecular phylogenetic research by Harrington et al. (2005)[2] has shown that while both the Aceraceae and Hippocastanaceae are monophyletic in themselves, their removal from the Sapindaceae sensu lato would leave Sapindaceae sensu stricto as a paraphyletic group, particularly with reference to the genus Xanthoceras.
