It had long been thought, at least by some, to belong in the order Celastrales.[1] In a phylogenetic study of that order in 2006, Pottingeria was found to be a member of the order, but not of any of its families. It was in an unresolved pentatomy consisting of Parnassiaceae, Pottingeria, Mortonia, the pair (Quetzalia + Zinowiewia), and the other genera of Celastraceae.[2] When the APG III system was published in October 2009, the Angiosperm Phylogeny Group expanded Celastraceae to include all members of the pentatomy mentioned above.[3] Armen Takhtajan had placed Pottingeria in a monotypic family in 1987,[4] but he later treated it as a subfamily of Celastraceae.[5]
