The genus Morinda (Morindeae, Rubioideae. Rubiaceae) is closely allied to Coelospermum, Gynochthodes , and Pogonolobus , but differs from these genera in inflorescence and pollen morphology. In this revision of Morinda in New Caledonia fourteen species are recognized, one of which is subdivided into four varieties. Eleven species are endemic to the area. Two new species, M. mumtana and M. truneata , and one new variety, M. myrtifolia var. vrevifolia , are described. Two recombinations, M. myrtifolia var. choriophylla and M. myrtifolia var. velutina , are made. All taxa are illustrated with line drawings and their distributions mapped, and a key to the species is presented. Phylogenetic analyses including nineteen species are presented.
