THE GENUS ACACIA S.L. IN PAKISTAN

Abstract

The molecular studies clearly indicate that Acacia s.l. is non-monophyletic and there is robust support for the recognition of five genera. Hence the classical identity of Acacia has to change. The pros and cons of typifying and retypifying Acacia by different types are discussed. It is argued that under the circumstances, the only option available is to accept the decision taken at the XVIII International Botanical Congress at Melbourne. Consequently the current position of various taxa present in Pakistan, formerly placed in Acacia s.l., have been transferred to Acacia s.s. Vachellia and Senegalia. This has resulted in five new combinations in the genus Vachellia and one new combination in Senegalia.
