The light green sessile phyllodes have a quadrangular shape and have a yellow nerve at apex of each angle. The phyllodes have a length of 1.5 to 4.5 cm (0.59 to 1.77 in) and a width of 1 to 1.3 mm (0.039 to 0.051 in). The rudimentary inflorescences are found on one or two branched racemes with an axes that has a length of 1 mm (0.039 in).

It was reclassified as Racosperma atrox by Leslie Pedley in 2003 then transferred back to the genus Acacia in 2011.[3]
