DOIAbstract
Storthocalyx is one of four genera of Sapindaceae endemic to New Caledonia. The most recent taxonomic revision is >60 years old and is based on material that represents <10% of the collections available today. Four species are currently recognized: Storthocalyx chryseus, Storthocalyx leioneurus, Storthocalyx pancheri, and Storthocalyx sordidus, although a significant number of specimens cannot be assigned to any of them. One hundred and ninety-eight herbarium specimens were examined for an ascendant hierarchical classification and a principal coordinates analysis based on 19 morphological characters regarded as diagnostic at the species level (including those used in the original revision). The analyses revealed five morphologically well de...
