Notes

This plant is evidently similar to 6. O. umbelliferum described by Rumphius. However, a number of differences make it unlikely that it is the same species. The diameter of the inflorescence of the Halmaheira plant is only about half that given by Rumphius; the lateral rays of the inflorescence are distinctly articulated near the base, a feature now shown in Rumphius' figure; and the sterile bacciform flowers are long-pedicelled, whereas Rumphius described and figured his as borne in capitula.
