The placement of Berberidopsidales has been quite problematic. This name is new, only recognised in the Apg3 classification. Berberidopsidales is a close ally of Caryophyllales. The Apg2 classification left the members unplaced as to order, assigning them to the core eudicots.
The Order Berberidopsidales has 2 families: Berberidopsidaceae and Aextoxicaceae.
In the Plant system they are tentatively placed as Subclass 1 of the Asteranae.
Aextoxicaceae: 1 genus and 1 species: Aextoxicon punctatum.
Berberidopsidaceae: Berberidopsis, 2 species, Streptothamnus, 1 species; often treated as belonging to Flacourtiaceae.
