Figure 1: Map of sampling region in South Australia.

Population sampling locations of Dodonaea viscosa ssp. angustissima are indicated by coloured circles, where colours represent genetic cluster assignment from population genetic structure analysis: blue = Kangaroo Island cluster; green = Flinders/Gammon ranges cluster; red = Eastern cluster. Map shading represents elevation with darker shading indicating higher elevation (© Commonwealth of Australia (Geoscience Australia) 2016).
