IntroductionThe 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
Hydrogen series of the
Asteranae.
FamiliesAextoxicaceae: 1 genus and 1 species:
Aextoxicon punctatum.
Berberidopsidaceae: Berberidopsis, 2 species, Streptothamnus, 1 species; often treated as belonging to
Flacourtiaceae.
