Mont Panié, the highest mountain on New Caledonia, has a rich and distinctive flora. A new species was recently collected and is here described in the genus Symplocos (Symplocaceae), which is now represented by seven species in New Caledonia, all endemic. Symplocos paniensis Pillon & Nooteboom, sp. nov. is most similar to S. neocaledonica (Vieill.) Nooteboom, from which it differs by its shorter leaves with rounded apex, and the more even disposition of the leaves along the twigs. This provides further evidence that the Mont Panié chain, which also includes Mont Colnett and Mont Ignambi, is still under-collected.
