Flore de la Nouvelle-Calédonie is an ongoing multi-volume flora describing the vascular plants of New Caledonia in the South-West Pacific. published by the National Museum of Natural History in Paris since 1967. Each species treatment typically includes taxonomic information, morphological description, a line drawing and a distribution map. Originally published as Flore de la Nouvelle-Calédonie et Dépendances, since 2014 it has been renamed shortly Flore de la Nouvelle-Calédonie and is co-published with Institut de Recherche pour le Développement in a fully colored format. Flore de la Nouvelle-Calédonie currently consists of 27 volumes, covering little over 50% of a total of approximately 3,400 species native to the New Caledonian archipelago. Major botanical families awaiting treatment include Rubiaceae, Cyperaceae, Rutaceae, and Poaceae.
