Limeum madagascariense, a new species and the first record of Limeaceae in Madagascar

The distribution of Limeum, the single genus in Limeaceac, has been considered limited to continental Africa, SW Asia and India. Limeum madagascariense Sukhor., a new species described here, is the first member of the genus reported from Madagascar. It was recorded from the area surrounding Mahajanga in the northwest of the island. The species can be easily distinguished from all congeners by its twining habit, unique within the genus, and long-attenuate leaves.
