Octomeles
Octomeles is a monotypic genus of plant in family Tetramelaceae. The sole species is Octomeles sumatrana, sometimes written O. sumatranum. Octomeles sumatrana, commonly called Benuang, or Ilimo, 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. Description
The tree is dioecious and large: reaching up to   in height and up to thirteen feet (four meters) in diameter above the buttresses. A pioneer species, it regenerates quickly in disturbed habitats such as logged forest and previously cultivated land. It has been known to grow as much as  in height and up to  diameter at breast height (DBH) in just four years, equivalent to annual rings 2.3 inches (six centimeters) wide. Also, like other pioneer species, it is relatively short lived; even the emergent titans rarely exceeding 85 years of age. It also has noteworthy buttresses; up to 19.5 feet (six meters) high by up to  in length. On Bougainville the buttresses take a different form; higher and narrower, up to  in height while only  in length. References
