Sapindaceae, as described above, include Aceraceae and Hippocastanaceae, as recommended by APG4. The major additions are that the Aceraceae have opposite leaves and that the Hippocastanceae has digitately compound leaves and that both often have bisexual flowers, the Aceraceae sometimes having a mix of unisexual and bisexual flowers. When included in the Sapindaceae, they are often treated as subfamilies. They are not present in Somaliland or Somalia.
