Comments
McTaggart et al. (2014) determined the rusts on Goodeniaceae, Puccinia stylidii (Stylidaceae) and P. lagenophorae (Asteraceae) were closely related and may be the product of sympatric speciation after host jumps in a shared environment. Puccinia brunoniae is distinguished from the rusts on Goodeniaceae as it occurs on Brunonia australis.
