title: A revision of the fern genus Oleandra (Oleandraceae) in Asia.
abstract: The Asiatic species of Oleandra (Oleandraceae) are revised. We reduce a large number of species to Oleandra neriiformis and Oleandra sibbaldii, we provide a revised circumscription of Oleandra cumingii and Oleandra undulata and we establish the identity of Oleandra vulpina. In total, we recognize 9 species, with full synonymy, descriptions and distribution maps. A list of identifications is appended.
