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.
Given the similarity in flower colour and shape (In nearly all species, the five petals are obovate), the number of stamens is a useful method of identification as this can vary widely from 4 to about 200 depending on species.
