Notes
The spherical inflorescence is characteristic, having straight rigid rays with no articulation on the secondary branches, and the pseudo-fruits are well separated from the true flowers. Miquel distinguished Trevesia zippeliana because the collector noted that its ovary was 4-celled. Possibly this number related to the sterile flowers. In two gatherings from Ambon (Waai, Teysmann; G. Salhutu, Boerlage 179) the fertile flowers are subsessile in heads, but otherwise conform to the characters of this species. The only record of this genus from the Tenimber Is. consists of leaves only, but their characters conform to this species.
