Page "Rosales" Paragraph 2

The order Rosales is strongly supported as monophyletic in phylogenetic analyses of DNA sequences, such as those carried out by members of the Angiosperm Phylogeny Group.

In their APG III system of plant classification, they defined Rosales as consisting of the nine families listed in the taxobox on the right.

The relationships of these families were uncertain until 2011, when they were resolved in a molecular phylogenetic study based on two nuclear genes and ten chloroplast genes.
