Two new, orange-flowered Tephrosia (Fabaceae: Millettieae) species from the Kimberley region, in Western Australia’s monsoon tropics

BUTCHER, R., Nuytsia 32 : 39–50 (2021)

Ongoing taxonomic revision of Tephrosia Pers. in Australia is continuing to identify new taxa from study of existing herbarium collections as well as new material gathered from remote and under-collected areas. The Kimberley region of Western Australia is recognised for its biodiversity and endemism, but the recognition of new species is hampered by its inaccessibility, especially to areas of relief with complex microhabitats and refugia. It is from these areas that many recently described species, from across the Western Australian flora, have been collected. This paper describes and illustrates two new, poorly known, orange-flowered species of Tephrosia from the Kimberley region: T. cowiei R.Butcher, a close ally of the Northern Territory’s T. bifacialis Cowie, and T. funicularis R.Butcher, a distinctive new species from sandstone habitats.

Redefinition of Tephrosia supina (Fabaceae: Millettiae), a north-west Western Australian endemic, and description of two similar species

BUTCHER, R. AND COWIE, I.D., Nuytsia 32 : 67–83 (2021)

The application of the name Tephrosia supina Domin is clarified herein, with this species determined as being a north-west Western Australian endemic subshrub with pink-purple flowers; T. supina s. str. is differentiated from two similar taxa, which also occur in the Northern Territory and Queensland. These are described herein as T. insolens R.Butcher & Cowie and T. lithosperma R.Butcher & Cowie, and T. supina is lectotypified. Full descriptions and images are provided for these three species and their histories and affinities are discussed.
