Hippocastanoideae

Hippocastanoideae is a subfamily of flowering plants in the soapberry family Sapindaceae. The group was formerly treated as the separate families Aceraceae and Hippocastanaceae. Molecular phylogenetic research by Harrington et al. (2005) 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.

Dipteronia is a genus with two living and one extinct species in the soapberry family Sapindaceae. The living species are native to central and southern China. The fossil species has been found in Middle Paleocene to Early Oligocene sediments of North America and China.

Billia is a genus of trees in the family Sapindaceae and native to the Americas, from central Mexico to Ecuador. The wood is used in carpentry.
