A Hippocastanaceae occurs as little personal, using a virtually all far flung genus Aesculus (the horsechestnuts), which in todays world is taken to include Pavia (a buckeyes). Still, a U.s. genus Billia and the Chinese genus Handeliodendron should also become members of the personal. The feature of the personal is the palmate compound leaves.

A personal is closely related the big, mostly tropical personal Sapindaceae, and these times these are green for each Aceraceae and Hippocastanaceae to be involved in the Sapindaceae s.l. Better grounds to believe and then far shows from each one one deuce little families to exist as monophyletic (we.e. it is "good" groups) & to become radical to Sapindaceae. Inclusion (or even non) occurs as matter of taxonomical opinion, like than of firm fact.
