Abstract

Re-examination of nomenclature of three Indo-Chinese species, Clerodendrum adenocalyx, C. nhatrangense and C. palmatolobatum reveals that their names are invalidly published according to Article 39.1. in the International Code of Nomenclature for Algae, Fungi, and Plants (ICN): all these species published in 1935 were described without a Latin diagnosis. Our study validates these species names and, in addition, C. adenocalyx is formally reported as a new record from Vietnam. Species description, distribution, ecological information and IUCN conservation status are provided.
