TaxonomyThis order consists in Apg3 of the families
Nelumbonaceae,
Platanaceae,
Proteaceae.
In the
Plant theory more Orders and Families are included like
Buxaceae,
Gunneraceae,
Sabiaceae, Trochondendraceae and
Vitaceae. These families are close relatives to
Proteales. Including them in
Proteales will make
Proteales paraphyletic. But that is seen in the same way as
Gymnospermae: a group from where new evolution as arisen. To make the group monophyletic the new evolution should be included but that would make the group too extensive.
