Shown here: Leaves dull (not glossy nor shiny) . Leaves' margins toothed . (In the NSW–Vic. native *Clematis* spp. the leaves' undersides colour has been loosely said to identify the species, but that's not accurate nor consistent, for an identifying feature, as for example *Clematis aristata* may have purple leaves' undersides or green leaves' undersides or white-hairy leaves' undersides, etc. ) .
