The Anisophylleaceae are a small family with four genera and 71 species, in the order Cucurbitales, according to the APG II. However, it is more isolated from the other suprafamilal clades in this order, while it shows some similarities in flower morphology with the genus Ceratopetalum (family Cunoniaceae, order Oxalidales). Several wood features of this family are more primitive than those of the other families in the order Cucurbitales. Previously, this family was categorized under its own order, Anisophylleales, by Takhtajan in 1997.
