Berberidopsidaceae is the botanical name for a family of flowering plants. Such a family has been recognized by only a few taxonomists: the plants involved have often been treated as belonging to family Flacourtiaceae.
The APG II system, of 2003 (unchanged from the APG system, of 1998), does recognize this family, unplaced as to order and merely assigned to the clade core eudicots. The family consists of one or two genera, Berberidopsis, with two species and Streptothamnus, with a single species.
However, APG II mentions the possibility of recognizing an order Berberidopsidales, which would comprise the two families Aextoxicaceae and Berberidopsidaceae.
