A review of Hibbertia hemignosta and its allies (Dilleniaceae) from Western Australia

The group of species that includes Hibbertia hemignosta (Steud.) J.R. Wheeler is reviewed and a key provided. The new species Hibbertia acrotrichion J.R. Wheeler and Hibbertia chartacea are described. Two new varieties of Hibbertia hibbertioides (Steud.) J.R. Wheeler, var. meridionalis and var. pedunculata, and two new varieties of Hibbertia pulchra Ostenf., var. acutibractea and var. crassinervia, are also described. All taxa are mapped and illustrated. Both new species have conservation priority, but the four new varieties are not considered endangered.
