Sometimes these genera have been placed in either the Grossulariaceae or the Saxifragaceae.

Escalloniaceae sens. lat. has been shown to include a number of unrelated groups, here separated as Argophyllaceae, Quintiniiaceae and Rousseaceae. Polyosma may also be better placed in its own family, but further study is needed.
