[1] The species was first formally described by botanist Ferdinand von Mueller in 1882 as part of the work Definitions of some new Australian plants as published in Southern Science Record.

It was reclassified as Racosperma estrophiolatum by Leslie Pedley in 1987 then returned to the genus Acacia in 2001.

It is then ground and mixed with a little water, then left to set again to a chewable gum, and eaten with a small stick.
