Abstract

In Zehneria thwaitesii long standing uncertainties persisted with respect to taxonomic delimitation. This study is a first step in clarifying the case using both morphological and molecular phylogenetic analyses. We here provide a complete overview on the nomenclatural history of Z. thwaitesii. For the African plants hitherto included in the broadly circumscribed species the name Z. tridactyla is reinstated and a lectotype is designated. Diagnostic features distinguishing both taxa are summarised. Z. thwaitesii is now considered restricted to Asia.
