Acacia nanodealbata differs from A. dealbata in having crowded (almost touching to overlapping), almost glabrous pinnules which are less than 2.5 mm long and have an obtuse apex. The pinnules of Acacia dealbata subsp. alpina are generally longer and less stout than those of A. nanodealbata. The overall aspect of the tree is generally greener than the typical grey-green of A. dealbata.

Despite the common name, A. nanodealbata is rarely of 'dwarf' habit and often of similar stature to A. dealbata.
