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.

Corrigendum to: 50 years of botanical discovery: a golden anniversary edition of Nuytsia, the journal of the Western Australian Herbarium

WEGE, J.A. AND SHEPHERD, K.A., Nuytsia 32 : 85 (2021)

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.

Isotropis petrensis (Fabaceae: Mirbelieae), a new species from arid Western Australia

DAVIS, R.W. AND WEGE, J.A., Nuytsia 32 : 99–102 (2021)

Styphelia undulata (Ericaceae: Epacridoideae: Styphelieae), a distinctive, short-range endemic from the Geraldton Sandplains

HISLOP, M., Nuytsia 32 : 103–107 (2021)

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.

Eucalyptus merleae (Myrtaceae), a new rare species endemic to Ravensthorpe Shire in south-west Australia

MCQUOID, N.K. AND FRENCH, M.E., Nuytsia 32 : 151–158 (2021)

Eucalyptus merleae McQuoid & M.E.French, first collected by Ian Brooker in 1985, is described and illustrated. It is related to Eucalyptus astringens Maiden. The new species has a scattered distribution in the Ravensthorpe to Hopetoun area on the central south coast of Western Australia, is at risk from frequent fire, climate change and potential mining activity, and is in need of further survey and monitoring.

Convolvulus pyrophilus (Convolvulaceae), a new post-fire ephemeral, and an updated illustrated key to the Western Australian species

NAZAROVA, O. AND HISLOP, M., Nuytsia 32 : 159–165 (2021)

Taxonomic notes on Calandrinia remota (Montiaceae) and a reassessment of the status of C. polyandra var. leptophylla and C. polyandra var. monantha

Austrobaeckea, a new south-western Australian genus of Myrtaceae (Chamelaucieae: Hysterobaeckeinae)

RYE, B.L., Nuytsia 32 : 173–197 (2021)

The new Myrtaceous genus Austrobaeckea Rye is described, with eight species recognised. It is a member of tribe Chamelaucieae DC. subtribe Hysterobaeckeinae Rye & Peter G.Wilson and is restricted to the southern part of the South West Botanical Province of Western Australia. Three new species are named as A. columnaris Rye, A. fascifolia Rye and A. narembeen Rye, and the following new combinations are made: A. latens (C.R.P.Andrews) Rye, A. pygmaea (R.Br. ex Benth.) Rye, A. pachyphylla (Benth.) Rye, A. uncinella (Benth.) Rye and A. verrucosa (Turcz.) Rye. A lectotype is selected for A. uncinella. Three species have conservation priority.

New species of Western Australian Styphelia (Ericaceae: Epacridoideae: Styphelieae) from the S. pendula and S. conostephioides groups

HISLOP, M., Nuytsia 32 : 199–238 (2021)

Eight new species and one new subspecies are described and illustrated. Six of these, S. caudata Hislop, S. globosa Hislop, S. graniticola Hislop, S. intermediana Hislop, S. intricata Hislop and S. madida Hislop belong to the S. pendula (R.Br.) Spreng. group (also known as Group V), and the other two, S. carolineae Hislop and S. exarata Hislop, are from the S. conostephioides (DC.) F.Muell. group (also known as Group VIII). Styphelia madida includes the subspecies hirtigera Hislop. A key is provided to species of the S. pendula group occurring in the south-west corner of Western Australia (i.e. west of a line between Perth and Albany), this being the main region of diversity for the group. Five of the new species have conservation coding.
