The gap between Borneo and New Caledonia is largely filled by the related sect. Rumphius which overlaps this section geographically only slightly. The primary bud scales in sect. Rumphius rather than being completely imbricate and overlapping more or less meet at their apices with usually one or more actually curling outward at their apex while, in addition, the pollen cones in sect. Rumphius are normally in clusters of more than three and all the species of sect. Rumphius occur as large canopy trees.
