New combinations of Hibbertia (Dilleniaceae) segregated from H. hibbertioides and H. glomerata

Infraspecific taxa within the southwest Australian species Hibbertia glomerata Benth. and H. hibbertioides (Steud.) J.R.Wheeler are critically re-evaluated. Morphological evidence is presented to recognise H. glomerata subsp. wandoo J.R.Wheeler and H. hibbertioides var. meridionalis J.R.Wheeler at species rank, as H. wandoo (J.R.Wheeler) T.Hammer & K.R.Thiele and H. meridionalis (J.R.Wheeler) T.Hammer & K.R.Thiele respectively. Hibbertia hibbertioides var. pedunculata J.R.Wheeler is reduced to synonymy under H. hibbertioides. The remaining subspecies in H. glomerata are provisionally retained but are marginally distinct.
