Towards a monophyletic (Rutaceae): Phylogenetic placement of and other New Caledonian genera, and an updated infrageneric classification of .

(Rutaceae) is a scarcely known monotypic genus from New Caledonia. It is one of the few genera of Rutaceae that has never been included in a molecular phylogenetic study. Based on Sanger sequencing of the markers ETS, ITS, and L-F, we conclude that is nested within the large genus and that it is most closely related to other New Caledonian species of . Previous molecular phylogenetic studies revealed that other New Caledonian genera - namely the endemic , , , and the near-endemic (only one out of the nine species is not endemic to New Caledonia) - are nested in as well and we propose nomenclatural changes to render monophyletic and develop a new classification system for the genus.
