 Subspecies "evoluta" is found further inland in the Sydney region, from Hill Top in the southwest to Glen Davis in the northwest and Putty to the north.The subspecies are distinguished by leaf shape, the former having narrow linear leaves, 0.75 to 1.5 mm wide, with revolute margins, and the latter spoon- or oval-shaped (spathulate to elliptic) leaves measuring 1.5 to 5 mm wide, with recurved margins.There is a wide zone where intermediate forms are found from the Lower Blue Mountains to 15 km (8 mi) of the coast.
