The species was first formally described by the botanist Ferdinand von Mueller in 1859 as part of the work Contributiones ad Acaciarum Australiae Cognitionem published in the Journal of the Proceedings of the Linnean Society, Botany. It was later reclassified as Racosperma megalanthum in 1987 by Leslie Pedley and transferred back to the genus Acacia in 2001. [3]
