Hibbertia

Hibbertia, or Guinea flower, is a genus of trees, shrubs, trailing shrubs and climbers of the family Dilleniaceae. The five-petalled flowers of all species are varying shades of yellow, with the exception of H. stellaris, H. miniata and H. selkii, a recently named (1980s) species from the Stirling Ranges, which all have orange flowers. Around 150 species occur in Australia of which two are also found in New Guinea. Additionally, 24 species occur in New Caledonia, one of which is also found in Fiji, and one other species is endemic to Madagascar. The genus is currently being revised by Helmut Toelken of the South Australian Herbarium.
