Abstract

The close biotic link between Africa and Madagascar has led to many interesting taxonomic and phylogenetic questions. It has been suggested that the African-Madagascan genus Protorhus and the African-Madagascan species of Rhus s.l. are paraphyletic, but definitive evidence has been lacking. We investigated a clade of Anacardiaceae subfamily Anacardioideae in order to clarify evolutionary relationships and taxonomic rankings of the African-Madagascan members of these two genera. Phylogenetic analysis of sequence data from cpDNA trnL-trnF, and nrDNA ETS and ITS provide strong statistical support for the 1) paraphyly of Protorhus; 2) monophyly of Madagascan Protorhus species; 3) paraphyly of Madagascan Rhus. These results support the need for new circumscriptions of African Protorhus and new generic classifications for the Madagascan species of these two genera. Two nomenclatural changes are proposed, recognizing two former Rhus species in Searsia.
