Abstract

Examination of specimens from the Marquesas Islands, French Polynesia, disclosed the presence of an undescribed species of Jacquemontia Choisy from the uninhabited island of Mohotani: the new species Jacquemontia mohotaniensis is described here and its conservation status is proposed as critically endangered. To place this novelty in context, a review of the native and naturalized Indo-Pacific taxa of Jacquemontia is provided; 14 names are accounted for and some taxonomic problems are highlighted for future study. New combinations are made for two Australian species, J. distigma (Benth.) Halford and J. flexuosa (Spreng.) Halford; a second step typification is provided for the latter name to stabilize the nomenclature.
