Taxonomic notes on Asterolasia (Rutaceae) in Western Australia to inform conservation
WEGE, J.A., Nuytsia 28: 141–146 (2017)
Following examination of collections at the Western Australian Herbarium, the Threatened species Asterolasia nivea (Paul G.Wilson) Paul G.Wilson is synonymised under A. grandiflora (Hook.) Benth. A revised description is provided for A. grandiflora, a geographically restricted species that will remain listed as Priority Four under Department of Parks and Wildlife Conservation Codes for Western Australian Flora despite its expanded circumscription. Asterolasia pallida Benth. subsp. hyalina Paul G.Wilson, a distinctive taxon previously only known from Dryandra State Forest, is raised to species level and A. sp. Kalgan River (S. Barrett 1522), which is listed as Threatened in Western Australia, is treated as synonymous. While the latter action greatly expands the known range of A. hyalina (Paul G.Wilson) Wege, this taxon retains its conservation ranking of Priority Two. A key to species of Asterolasia F.Muell. in Western Australia is provided.
Acacia nicholsonensis (Fabaceae), a new ‘Minni Ritchi’-barked species of Acacia sect. Juliflorae from the Gulf of Carpentaria region of Northern Australia
CUFF, N.J. AND COWIE, I.D., Nuytsia 28: 147–158 (2017)
Acacia nicholsonensis Cuff is described as a new species of Acacia Mill. sect. Juliflorae (Benth.) Maiden & Betche. Acacia nicholsonensis is currently only known from the upper Nicholson River catchment in the far east of the Northern Territory where it is restricted to the levees and banks of major river channels. A key to the ‘Minni Ritchi’-barked Acacia species of the Top End of the Northern Territory and adjacent regions of tropical northern Australia is presented. The conservation status and ecology of the new species are discussed.
New lectotypes and synonyms in the Western Australian genus Scholtzia (Myrtaceae: Chamelaucieae)
RYE, B.L., Nuytsia 28: 159–167 (2017)
Lectotypes are selected for the genus Scholtzia Schauer and for S. capitata F.Muell. ex Benth., S. leptantha Benth., S. oligandra F.Muell. ex Benth., S. parviflora F.Muell. and Baeckea obovata DC. Scholtzia obovata (DC.) Schauer is reinstated and S. leptantha reduced to a synonym of it. Two informal names are made redundant by the lectotypifications. Brief descriptions are provided for these taxa as now defined.
