During the preparation of the Vascular Flora of the Marquesas Islands and Flore de la Polynesie francaise, four new species of Ixora L. ( Rubiaceae) have come to light and are described and illustrated herein: Ixora jourdanii Mouly and J.Florence, Ixora tahuataensis Mouly and J.Florence, Ixora uahukaensis Lorence and W.L.Wagner, and Ixora uapouensis Lorence and W.L.Wagner. In addition to these new taxa, the following three species of Ixora previously described from the Marquesas are recognized: Ixora marquesensis F. Br., Ixora ooumuensis J.Florence, and Ixora spathoidea F. Br. As the Marquesan environment is under serious threat from human impact, feral animals and weeds, the conservation status was estimated for each Ixora species. It is concluded that all Marquesan taxa are in need of inclusion in the IUCN Red List, their status ranging from endangered to critically endangered.
