Previously regarded as a variant of A. halliana. Acacia simmonsiana may be distinguished from that species by the glabrous branchlets, smaller phyllodes and heads, and terete pods that are not clearly constricted between seeds. It may also resemble A. ×grayana, which is distinguished by its hairy new shoots and peduncles, and caducous stipules.
