Named after Joseph Henry Maiden (1859-1925), a former Government Botanist and Director of the Royal Botanic Gardens, Sydney. Acacia maidenii is related to A. longifolia, A. floribunda and A. longissima but may be distinguished from these by the usually yellowish hairs on the peduncles. Frequently subject to borer attack. It may also spread by suckering, particularly if the roots are damaged. (T. Tame, Acacias of Southeast Australia, 1992).
