The Zygophyllales are an order of dicotyledonous plants, comprising the following two families:
- Family Zygophyllaceae
- Family Krameriaceae
According to the
Eurosids I.[1] The APG III system of 2009, however, recognized this order. Even if the monogeneric family Krameriaceae shares few common traits with the family Zygophyllaceae, researchers see little advantage in keeping it as a separate family (e.g. Sheahan and Chase). The name Zygophyllales can be used if one finds it appropriate to place both families into an order.[2] The order remains unchanged in the APG IV system.[3]
