Natural populations

The subtropical distribution of Goodenia rotundifolia is north of the Hunter River, New South Wales to the Mackay coast, Queensland with populations on the coast and tablelands. A perennial herb, G. rotundifolia grows in open eucalypt forest and woodlands in grassy understoreys, on the margins of wet sclerophyll forest, in coastal Melaleuca swamps and Banksia headlands. It is a very variable species particularly in density of the hairs covering the leaves and in plant habit; it may be prostrate, erect or stoloniferous [83].
