Proteales is the botanical name of an order of flowering plants consisting of two (or three) families. The Proteales have been recognized by almost all taxonomists.
In the classification system of Dahlgren the Proteales were in the superorder Proteiflorae (also called Proteanae).The APG II system of 2003 also recognizes this order, and places it in the clade eudicots with this circumscription:
with "+ ..." = optionally separate family (that may be split off from the preceding family).
The APG III system of 2009 followed this same approach, but favored the narrower circumscription of the three families, firmly recognizing three families in Proteales: Nelumbonaceae, Platanaceae, and Proteaceae. The Angiosperm Phylogeny Website, however, suggests the addition of Sabiaceae, which was not placed in an order in the eudicots in the APG III system, would be sensible.
The APG IV system of 2016 added family Sabiaceae to the order.
Well-known members of the Proteales include the proteas of South Africa, the banksias and macadamias of Australia, the London plane, and the sacred lotus. The origins of the order are clearly ancient, with evidence of diversification in the mid-Cretaceous, over 100 million years ago. Of interest are the current family distributions, with the Proteaceae a mostly Southern Hemisphere family, while the Platanaceae and Nelumbonaceae are Northern Hemisphere plants.
