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.

Rubinoboletus phaseolisporus (Boletaceae) from Western Australia is a Tylopilus with bean-shaped spores

OSMUNDSON, T.W., BOUGHER, N.L., ROBINSON, R.M. AND HALLING, R.E., Nuytsia 32 : 87–97 (2021)

The bolete genus name Rubinoboletus Pilát & Dermek has been misapplied in the past to include taxa belonging to several genera including Tylopilus P.Karst. In this study, we provide morphological and molecular phylogenetic justification for alignment of Rubinoboletus phaseolisporus T.H.Li, R.N.Hilton & Watling in Tylopilus with the North American taxon T. balloui (Peck) Singer. Thus, a new combination, Tylopilus phaseolisporus (T.H.Li, R.N.Hilton & Watling) Osmundson, Bougher, R.Rob. & Halling, is proposed for this brightly-coloured species that is apparently endemic to bushland in south-west Western Australia.

Tephrosia sabulosa (Fabaceae: Millettieae), a new species from Australia’s sandhill deserts

BUTCHER, R., Nuytsia 32 : 109–119 (2021)

The new species described herein has been segregated from the complexes surrounding T. rosea Benth. and T. brachyodon Domin, both of which are extremely challenging taxonomically. Tephrosia sabulosa R.Butcher is distinctive; however, its relationship with the other members of these complexes is not yet known. It occurs in sandhill habitats on the crests and slopes of dunes and has a disjunct distribution in Australia, with all but one collection being made from the Simpson-Strzelecki Dunefields bioregion of the Northern Territory, South Australia and Queensland; nearly 900 km lies between these collections and that made from the Kiwirrkurra Indigenous Protected Area (Gibson Desert bioregion) in Western Australia. The new species is described and differentiated from similar taxa, and images and a distribution map are provided.

A revision of Lasiopetalum (Malvaceae: Byttnerioideae) from the northern sandplains of Western Australia, including two new species

SHEPHERD, K.A. AND WILKINS, C.F., Nuytsia 32 : 121–149 (2021)

Taxonomic descriptions are provided for eight species of Lasiopetalum Sm. with a centre of diversity in the Geraldton Sandplains bioregion. Circumscriptions are updated for six species, namely L. angustifolium W.Fitzg., L. drummondii Benth., L. lineare Paust, L. ogilvieanum F.Muell., L. oldfieldii F.Muell., and L. oppositifolium F.Muell. Lectotypes are designated for L. angustifolium, L. ogilvieanum, L. oldfieldii, and L. oppositifolium, while the holotype for L. drummondii is clarified. In addition, two new species from the region are recognised and named here as L. biloculatum K.A.Sheph. & C.F.Wilkins and L. erectifolium K.A.Sheph. & C.F.Wilkins. Images and distribution maps are provided for all species.
