Hibbertia striata, a new combination for a long-overlooked Western Australian species, and inclusion of H. pachyrrhiza in H. huegelii

The common and widespread species Hibbertia huegelii (Endl.) F.Muell. comprises two distinct taxa, one of which matches the type of Candollea striata Steud., which is here recombined as Hibbertia striata (Steud.) K.R.Thiele. Hibbertia pachyrrhiza Steud. is reduced to a synonym of H. huegelii s. str. Descriptions and distribution maps are provided for both accepted species.
