Octomeles[2] is a monotypic genus of plant in family Tetramelaceae. The sole species is Octomeles sumatrana,[3][4] sometimes written O. sumatranum.[5]

Octomeles sumatrana is found in Brunei,, Indonesia, Malaysia, Papua New Guinea, the Philippines, and the Solomon Islands. It and Tetrameles nudiflora are the only two species in the family Tetramelaceae. They were previously classified in the Datiscaceae but found genetically to not form a natural clade with the other members of that family.[6]

The tree is dioecious and large: reaching up to 75 m in height. A pioneer species, it regenerates quickly in disturbed habitats such as logged forest and previously cultivated land.
