Acacia exudans is similar in many respects to A. rostriformis and A. verniciflua. Acacia rostriformis is distinguished from A. exudans by the branchlets having dense appressed hairs, distinct phyllode shape, and smaller flower heads. Acacia exudans is distinguished from A. verniciflua by its densely hairy peduncles, large (3–4 mm long) persistent basal peduncular bracts, and stipules that are usually persistent (caducous in A. verniciflua).
