In 2006, a study of DNA sequences showed that " Perrottetia " was misplaced in Celastrales and that it is sister to " Dipentodon " in Huerteales.

The first semblance of Malpighiales as now known came from a phylogeny of resurrected Hutchinson's name, though his concept of Malpighiales included much of what is now in Celastrales and Oxalidales.

The families into which " Lepidobotrys " had usually been placed, Linaceae and Oxalidaceae, are now placed in the orders Malpighiales and Oxalidales, respectively, which are closely related to Celastrales.

In 2005, a study of flower structure concluded that the family Parnassiaceae belonged in the order Celastrales with Lepidobotryaceae, and a broadly defined Celastraceae, including " Mortonia " and " Pottingeria ".

In 2006, Li-Bing Zhang and Mark Simmons produced a phylogeny of the Celastrales based on taxa that were not sampled, these results were confirmed by the second phylogeny of the Celastrales, which was produced by Mark Simmons and several co-authors in 2008.

The Phylocode definition includes Crossosomatales, Geraniales, Myrtales, Fabidae ( Celastrales, Cucurbitales, Fabales, Fagales, Huaceae, Oxalidales, Malpighiales, Rosales and Zygophyllales ), Malvidae ( Brassicales, Huerteales, Malvales, and Sapindales ) as they are defined in the APG III system.

In 2008, Simmons and others produced a phylogeny of the Celastrales that achieved better resolution than the 2006 study by sampling more species and more DNA . They found the same pentatomy of five strongly supported groups that the previous study had found, but only weak to moderate support for any relationships between the five groups.

The first very large DNA sequence comparison for flowering plants included both of them and was based on rbcL . The phylogeny produced by this study placed " Lepuropetalon " and " Parnassia " together, but only four members of Celastrales were sampled and the authors could not calculate statistical support for their clades.
