P. cunninghamii is usually distinguished from the very similar species P. drummondii by its smaller and always distinctly beaked fruits. The acute beak of the capsule is often vaguely quadrangular underlining its intermediate nature between P. drummondii and P. turrifera as Briggs et al. (1977) Flora of New South Wales, p. 34 pointed out.
