Tetramelaceae

The Tetramelaceae are a family of plants in the order Cucurbitales, containing two genera of mostly Asian, large trees, Octomeles and Tetrameles, each with a single species. These genera were formerly placed in the Datiscaceae, but genetic studies confirmed that they do not form a natural clade with the other members of that family.

Tetrameles is a genus of flowering plants in the family Tetramelaceae with one species, Tetrameles nudiflora. It grows as a large deciduous tree and is found across southern Asia from India through southeast Asia, Malesia, and into northern Australia.

Octomeles is a monotypic genus of plant in family Tetramelaceae. The sole species is Octomeles sumatrana, sometimes written O. sumatranum.
