Grey shading shows the distribution of specimens that are morphologically assigned to the ‘southern’ nrDNA group; samples from other areas are assigned here to the ‘northern’ group. Map is based on records in the Australasian Virtual Herbarium and our examination of specimens from MEL, NSW and CANB (primarily in terms of leaf shape, leaf size and habitat). NP, National Park; SF, State Forest.

We consider this option as untenable, given the degree of morphological, ecological and genetic differentiation within the pedunculate clade, and such a broad species concept is inconsistent with other species in the family and would seem unparalleled in current classifications of any other group in the Australian vascular flora.
