New Caledonia is an archipelago in the South Pacific. It includes the main island of Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines, and a few remote islets. Politically New Caledonia is a sui generis collectivity of France, while it is recognized as a distinct botanical country by the World Geographical Scheme for Recording Plant Distributions.
