A phylogenetic study of the Malpighiales has been made by Wurdack & Davis (2009). The family Hypericaceae is shown to be monophyletic and sister to Podostemaceae, whereas the family Clusiaceae is paraphyletic and comprises two unrelated subfamilies (Kielmeyeroideae and Clusioideae). The subfamily Clusioideae is treated as the family Clusiaceae, and the subfamily Kielmeyeroideae is circumscribed as the reinstated family Calophyllaceae (Wurdack & Davis 2009). Previously, some authors had placed Hypericum in Clusiaceae sensu lato.
