New combinations in the genus Vachellia (Fabaceae: Mimosoideae) from Australia

Abstract

Based on the evidence that the genus Acacia sens. lat. is polyphyletic and the acceptance that the major groups warrant generic status, and because the name Acacia has been conserved with a new type, the following new combinations in Vachellia Wight & Arn. are necessary for Australian taxa formerly included in Acacia subg. Acacia: Vachellia bidwillii (Benth.) Kodela, V. clarksoniana (Pedley) Kodela, V. ditricha (Pedley) Kodela, V. douglasica (Pedley) Kodela, V. pachyphloia (W.Fitzg.) Kodela and V. pachyphloia subsp. brevipinnula (Tindale & Kodela) Kodela, V. pallidifolia (Tindale) Kodela, V. suberosa (A.Cunn. ex Benth.) Kodela, V. sutherlandii (F.Muell.) Kodela, and V. valida (Tindale & Kodela) Kodela. Vachellia farnesiana (L.) Wight & Arn., a pre-European introduction to Australia, has previously been transferred to the genus. Acacia nilotica (L.) Delile has been left for the attention of other researchers more familiar with this taxon, its synonymy and its various subspecies. © 2006 Royal Botanic Gardens and Domain Trust.
