Acacia imitans is a low, intricately branched and semi-prostrate shrub 0.3-1 m tall by 3m across. Branches divide into numerous short, ridged, smaller branchlets which end in a spine. Phyllodes are asymmetrical in shape, the upper margin straight or slightly concave, the lower margin convex, 3.5-7 mm long, 1.5-2.5 mm wide, thin, hairless and sharp-tipped. They are not grouped in clusters and are often bent backwards on the branches. Inflorescences are singular at each node, on a stalk 3-4 mm long. The flower head is golden, 6-8 mm long and 4-5 mm wide. Pods are tightly coiled to 7 mm long (when coiled) and 3 mm wide (Maslin 1999).
This species has been confused with Acacia kochii which occurs in the same area. Phyllodes of A. kochii are 1-2 cm long, grouped in bundles of 2-8 with a spine associated with each bundle. Flower heads are 7-13 mm long on stalks 1-2 cm. Pods are to 9 cm long and are not tightly coiled. A. erinacea also occurs in the same area and has a similar habit, small phyllodes and branches that form spines. It can be distinguished from A. imitans by its globular flower heads and pods which are short, straight and oblong, c. 8mm wide (Maslin 1999).
