Research output: Contribution to journalArticle

Abstract

The Hibbertia commutata Steud. species group comprises 27 species in Hibbertia Andr. subgenus Hibbertia, all being endemic in south-western Western Australia; it is the largest species group in that state. Several taxa in the group have been the subject of considerable confusion in the past, with inadequate understanding of species boundaries leading to mixed determinations on specimens. All taxa in the group are treated here, and the following are described as new: Hibbertia acrotoma K.R.Thiele, H. ambita K.R.Thiele, H. barrettiae K.R.Thiele, H. davisii K.R.Thiele, H. elegans K.R.Thiele, H. hortiorum K.R.Thiele, H. improna K.R.Thiele, H. inopinata K.R.Thiele, H. sandifordiae K.R.Thiele, H. semipilosa K.R.Thiele, H. spectabilis K.R.Thiele, H. wheelerae K.R.Thiele.
