Oncotheca is the sole genus of the Oncothecaceae, which is one of three families of flowering plants endemic to New Caledonia. Its placement has been enigmatic for a long time, but a recent phylogenetic analysis[5] based on 73 plastid genes found it to be sister to Icacinaceae. It is now placed in the order Icacinales.[6][7]
