The nomenclature of a number of taxa that occur in Southeast Asia in Baeckea, Decaspermum, Leptospermum, Melaleuca, Psidium, Rhodamnia, Rhodomyrtus and Tristaniopsis is discussed: eight lectotypes are designated, six taxa are shown to have been previously lectotypified under Article 9.9 with second-stage lectotypification being deemed unnecessary for two of them, and comments are made on two species that we cannot yet typify.
