Pottingeria
''Pottingeria'' is a genus consisting of a single species, ''Pottingeria acuminata'', a small tree or large shrub native to mountainous areas of southeast Asia (Assam, Myanmar, and Thailand).〔
It had long been thought, at least by some, to belong in the order Celastrales. 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. 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.〔Peter F. Stevens (2001 onwards). (Celastrales ) At: Angiosperm Phylogeny Website. At: Missouri Botanical Garden Website.〕 Armen Takhtajan had placed ''Pottingeria'' in a monotypic family in 1987,〔James L. Reveal. 2008 onward. "A Checklist of Family and Suprafamilial Names for Extant Vascular Plants." At: Home page of James L. Reveal and C. Rose Broome. (see ''External links'' below).〕 but he later treated it as a subfamily of Celastraceae.〔"Celastraceae" pages 411-412. In: Armen L. Takhtajan (Takhtadzhian). ''Flowering Plants'' second edition (2009). ISBN 978-1-4020-9608-2.〕
