Hibbertia glaucophylla is the correct name for the Western Australian species currently known as H. rupicola (Dilleniaceae)

Abstract

There has been historical confusion and error in the application and typification of the name Pleurandra glaucophylla Steud., likely caused by a slip of the pen on the original collecting label which caused the collecting number assigned by Preiss (2179) to be mis-transcribed as 2159, a number already used for another Preiss collection. We show that the type of P. glaucophylla falls within the circumscription of the species currently known as Hibbertia rupicola (S.Moore) C.A.Gardner, necessitating the new combination H. glaucophylla (Steud.) K.R.Thiele & T.Hammer as the correct name for the species currently known as H. rupicola.
