Validating a striking new species endemic from New Caledonia: Pandanus bernardii H.St.John ex Callm., sp. nov. (Pandanaceae) and its monospecific section: Pandanus Parkinson sect. Bernardia B.C.Stone ex Callm., sect. nov.

A distinctive new species, Pandanus bernardii H.St.John ex Callm., sp. nov., endemic from New Caledonia, is described. The new species differs from other members of the genus in by the ornamentation of its drupes and the arrangement and shape of its stigmas. The species was already recognized by both H.St.John and B.C. Stone but was never validly published. The monospecific section: Pandanus Parkinson sect. Bernardia B.C.Stone ex Callm., sect. nov., validated here, is required to accommodate the unique morphology of the new species. Line drawings are provided for the new species, along with discussions of its morphological affinities and preliminary assessment of extinction risk following IUCN Red List Categories and Criteria.
