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

Abstract

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.
