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]
Species include:
- Polyosma alangiacea F.Muell. – White Alder[3]
- Polyosma brachyandrum Domin[3]
- Polyosma brachystachys Schltr.[4]
- Polyosma cambodiana Gagnepain – dou xian mu[5]
- Polyosma comptonii Baker f.[4]
- Polyosma cunninghamii Benn.[3]
- Polyosma discolor Baill.[4]
- Polyosma hirsuta C.T.White – Alder[3]
- Polyosma integrifolia Blume[5]
- Polyosma leratii Guillaumin[4]
- Polyosma pancheri Baill.[4]
- Polyosma podophylla Schltr.[4]
- Polyosma reducta F.Muell.[3]
- Polyosma rhytophloia C.T.White & W.D.Francis[3]
- Polyosma rigidiuscula F.Muell. & F.M.Bailey[3]
- Polyosma spicata Baill.[4]
