Tephrosia oxalidea (Fabaceae: Millettieae), a new species from the Pilbara and Gascoyne bioregions of Western Australia
BUTCHER, R. AND HURTER, P.J.H.

The Australian species of Tephrosia Pers. (Fabaceae: Millettieae) have not been revised in full since Bentham’s Flora Australiensis, although considerable work towards this goal has been performed at the herbaria of the Northern Territory (DNA) and Queensland (BRI) to date. Taxonomic work is now underway on the Tephrosia of Western Australia, with Western Australia’s plant census currently recording 23 informally named taxa in this State. One of these, Tephrosia sp. Cathedral Gorge (F.H. Mollemans 2420), is a distinctive species and is described herein as T. oxalidea R.Butcher & P.J.H.Hurter. Images and a distribution map for this species are included, as is a discussion of its affinities.
