Unabridged note: Acer and Aesculus have traditionally been placed in small families (Aceraceae and Hippocastanaceae, respectively). However, virtually all the traits considered characteristic of these two small families are also found in the closely related large family Sapindaceae, and it seems more reasonable to emphasize the close relationship of the whole group by treating it as a single family, rather than maintaining two small segregate families that differ from Sapindaceae in virtually nothing except opposite leaves (Harrington et al. 2005).
