Acacia sophorae (Labill.) R.Br., is treated here as a smaller growing, maritime subspecies of Acacia longifolia and is included in this record. However, some authorities recognize it as a distinct species[].
Classification of the genus Acacia (in the wider sense) has been subject to considerable debate. It is generally agreed that there are valid reasons for breaking it up into several distinct genera, but there has been disagreement over the way this should be done. As of 2017, it is widely (but not completely) accepted that the section that includes the majority of the Australian species (including this one) should retain the name Acacia, whilst other sections of the genus should be transferred to the genera Acaciella, Mariosousa, Senegalia and Vachellia[].
