The shrub or small tree typically grows to a height of 5 to 5 m (16 to 16 ft) and has a spreading habit with glabrous branchlets that are sometimes covered in a fine white powdery coating.

"Acacia honey" is not collected from plants in the acacia family, but rather from Robinia pseudoacacia, known as black locust in North America. These findings for the utilization of A. mearnsii bark extract deserve further attention and research for the implementation at larger scales, not only due to the improved properties given by the tannin extract to silver nanoparticles, superparamagnetic nanoparticles, nanocellulose films and nanofiber membranes, but mainly because this extract can be delivered from well-established procedures at a commercial scale, and can be provided at a relatively low cost. This meant that the Australasian lineage (by far the most prolific in number of species) would need to be renamed.
