An evaluation of genomic and chloroplast DNA together with morphological characters discovered that the part is polyphyletic, although the shut relationships of many species had been unable to be resolved. Acacia dealbata seems to be most carefully associated to A. mearnsii, A. nanodealbata and A. baileyana.[11]

Some authorities think about A. dealbata to be a variant of Acacia decurrens.[3]

The leaves are typically utilized in Indian chutney.[3]

Invasive species[edit]

In South Africa, the species is a Class 1 weed within the Western Cape (requiring eradication) and Class 2 weed (requiring management exterior plantation areas) elsewhere.[22] In New Zealand the Division of Conservation class it as an environmental weed.[23] In Spain, as a result of its colonizing potential and constituting a severe menace to native species, habitats or ecosystems, this species has been included within the Spanish Catalog of Invasive Unique Species, regulated by Royal Decree 630/2013, of two of August, being prohibited in Spain, besides the Canary Islands and the Balearic Islands, its introduction into the pure setting, possession, transport, site visitors and commerce.[24]
