Polyosma is a genus of about 60 species of trees native to south-east Asia. They occur from China south through south-east Asia to the east coast of Australia, and also in New Caledonia.

Its taxonomic placement has long been uncertain: it was traditionally placed in Grossulariaceae, but in the APG II system it was given its own family, Polyosmaceae, which was unplaced as to order within the euasterids II (campanulids) clade.[1] More recent research found Polyosmaceae to be a sister to the Escalloniaceae, so for simplicity's sake the Angiosperm Phylogeny Website now recommends the latter family be expanded to include this genus.[2]
