Taxonomy

It was originally published by Robert Brown in 1810 as a species of Persoonia. In 1975, Lawrence Alexander Sidney Johnson and Barbara G. Briggs erected the genus Acidonia, transferring a great many Persoonia species into it.Template:R Later, the circumscription of Acidonia was changed to include only A. microcarpa.Template:R

However, phylogenetic studies indicate that Acidonia is nested in the larger genus Persoonia, where it was once included.Template:R
