The inclusion of Anogeissus, Buchenavia and Pteleopsis in Terminalia (Combretaceae: Terminaliinae)

Abstract

Previous molecular studies have confirmed that Terminalia (Combretaceae: Terminaliinae) is paraphyletic, with Anogeissus, Buchenavia and Pteleopsis embedded in it. Proposals were put forward to integrate these genera in Terminalia, following earlier transfers to Terminalia of Bucida, Ramatuella and Terminaliopsis. We emphasize the need to assess the relationships in Terminaliinae before formal taxonomic name changes are considered. We investigate relationships of Anogeissus, Buchenavia and Pteleopsis in Terminaliinae by a phylogenetic analysis of nuclear ribosomal DNA internal transcribed spacer and plastid rbcL, matK, trnH-psbA and psaA-ycf3. Our results confirm previous findings showing that Anogeissus, Buchenavia and Pteleopsis are embedded in Terminalia and reinforce the need to enlarge Terminalia to include these three genera. New combinations for the species concerned are provided.
