(with "+ ..." = optional segregate of the preceding family)
The [[Cronquist system]] of 1981 used a somewhat different circumscription, including the following families:
*[[Staphyleaceae]]
*[[Melianthaceae]]
*[[Bretschneideraceae]]
*[[Akaniaceae]]
*[[Sapindaceae]]
*[[Hippocastanaceae]]
*[[Aceraceae]]
*[[Burseraceae]]
*[[Anacardiaceae]]
*[[Julianiaceae]]
*[[Simaroubaceae]]
*[[Cneoraceae]]
*[[Meliaceae]]
*[[Rutaceae]]
*[[Zygophyllaceae]]
The difference with the APG II system is not as large as may appear, as the plants in the families Aceraceae and Hippocastanaceae stay in this order at APG II (both included in family Sapindaceae). The species now comprising the family Nitrariaceae in APG II also belonged to this order in the Cronquist system as part of the family Zygophyllaceae, while those now in the family Kirkiaceae were present as part of the family Simaroubaceae.
