The single pair of pinnae have a length of 1 to 2 mm (0.039 to 0.079 in) and have two pairs of pinnules with a length of 6 to 10 mm (0.24 to 0.39 in) and a width of 0.7 to 1.5 mm (0.028 to 0.059 in). [3] It blooms from July to August and produces yellow flowers. [2]

It was reclassified as Racosperma epacanthum in 2003 by Leslie Pedley then transferred back to genus Acacia in 2006. [4]
