“The end of an enigma”, new subtribe and nomenclatural novelties in Asclepiadeae (Apocynaceae: Asclepiadoideae)

Abstract

A new name, Topea H. A. Keller, is proposed for the genus Aenigma H. A. Keller (Apocynaceae) because there is a preexisting phonetic homonym. In addition, based on molecular phylogenetic studies, the new, monogeneric subtribe Topeinae H. A. Keller & Liede, endemic to the southern cone of South America, is here described within the tribe Asclepiadeae
