[5] Octomeles sumatrana, commonly called Benuang, or Ilimo, is found in Brunei, Indonesia, Malaysia, Papua New Guinea, the Philippines, and the Solomon Islands.

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 (246 ft) in height and up to thirteen feet (four meters) in diameter above the buttresses.

[7] A pioneer species, it regenerates quickly in disturbed habitats such as logged forest and previously cultivated land.

Also, like other pioneer species, it is relatively short lived; even the emergent titans rarely exceeding 85 years of age.
