- Abstract
The recent worldwide effort to transfer all non-Australian taxa of A cacia s.l. mostly to the genera S enegalia and V achellia follows the acceptance of the proposed re-typification of the genus with an Australian species. The Madagascan species have, as yet, not been included in phylogenetic studies of A cacia s.l. and their position in the new generic classification of A cacia s.l. is therefore still unclear. In this study, plastid DNA sequence data were generated for seven Madagascan species, included in existing matrices for A cacia s.l. and analysed to assess the placement of these species. The results indicate that the Madagascan species are placed either in S enegalia or V achellia and conform to the morphological characters used to distinguish these genera, despite some taxa having unusual red flowers. New combinations are formalized for Senegalia baronii, S . hildebrandtii, S . kraussiana ssp . madagascariensis, S . menabeensis, S . meridionalis, S . pervillei, S . pervillei ssp . pubescens, S . polhillii, S . sakalava, S . sakalava ssp . hispida, V achellia bellula, V . myrmecophila and V . vigueri. Nomenclatural errors are also corrected for three African taxa and, as such, new combinations are provided for Senegalia fleckii, S . hamulosa and V achellia theronii. © 2015 The Linnean Society of London, Botanical Journal of the Linnean Society, 2015, 179, 288-294.
