Initially it comprised a group of plant species native to Africa and Australia, with the first species "A. nilotica" described by Linnaeus. Controversy erupted in the early 2000s when it became evident that the genus as it stood was not monophyletic, and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia was not closely related to the mainly African lineage that contained "A. nilotica"the first and type species. This meant that the Australian lineage (by far the most prolific in number of species) would need to be renamed. Botanist Les Pedley named this group Racosperma, which was inconsistently adopted. Australian botanists proposed that this would be more disruptive than setting a different type species ("A. penninervis") and allowing this large number of species to remain "Acacia", resulting in the African lineage being renamed to "Vachellia". This was officially adopted, but many botanists from Africa and elsewhere disagreed that this was necessary., Saudi Arabia, officially known as the Kingdom of Saudi Arabia (KSA), is an Arab sovereign state in Western Asia constituting the bulk of the Arabian Peninsula.
