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 kouaouana Pillon[4]
  • Polyosma leratii Guillaumin[4]
  • Polyosma pancheriana 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]
  • Polyosma subintegrifolia (Guillaumin) Pillon[4]
