TaxonomyIn the
Apg3 classification Euphorbiales is not recognised as an order, It is part of the Order
Malpighiales.
Malpighiales is a huge Order, containing about 16000 species, about 8% of the eudicots.
The research shows as main clades:Violales,
Euphorbiaceae,
Clusiaceae,
Ochnaceae,
Chrysobalanaceae,
Rhizophoraceae Malppighiaceae,
Linaceae all the the broad sense defined.
Besides there are small unplaced Families
Caryocaraceae,
Centroplacaceae, Hugoniaceae,
Humiriaceae, Irvingaceae,
Ixonanthaceae, Lophophyxidaceae,
Pandaceae,
Putranjivaceae.
In older classifications Mapighiales did not exist. Only the
Hutchinson classification has an Order Mapighiales, consisting of
Malpighiaceae.
Erythroxylaceae and
Humiriaceae.
In the
Plant theory Malpighiales is split in
Violales and
Euphorbiales and parts are tranfered to
Celastrales. In the first version
Euphorbiales was named
Malpighiales and was differently organised
