Western Australian plant taxa not collected for more than 50 years
GIBSON, N., Nuytsia 27: 139–164 (2016)
An analysis of the Western Australian Herbarium collections generated a list of 29 endemic taxa last collected between 1888 and 1965, which are not currently on the Presumed Extinct schedule. On review, four of these taxa are not of immediate concern. The remaining 25 taxa are predominantly shrubs, generally known from very few collections, and are concentrated in heavily cleared bioregions, particularly the Avon Wheatbelt. Two taxa, Ptilotus sericostachyus subsp. roseus (Moq.) Benl and Darwinia divisa Keighery & N.G.Marchant, are recommended for immediate nomination as Presumed Extinct, while the remaining taxa will require further survey and/or taxonomic work to resolve their conservation status. Further survey will be challenging given the general lack of specific geographical and habitat information available for these taxa.
A taxonomic revision of Beaufortia (Myrtaceae: Melaleuceae)
BURBIDGE, A.A., Nuytsia 27: 165–202 (2016)
Beaufortia R.Br. (Myrtaceae) is endemic to the south-west of Western Australia and is almost confined to the South-West Botanical Province, with a few species extending a short distance into the Eremaean. Twenty-two species are recognised in this revision of the genus, including three new species: B. burbidgeae A.A.Burb., B. kwongkanicola A.A.Burb. and B. raggedensis A.A.Burb. Beaufortia puberula Turcz. is reinstated and B. interstans F.Muell. placed into synonymy under it. Lectotypes are selected for B. anisandra Schauer, B. dampieri A.Cunn., B. elegans Schauer, B. empetrifolia (Rchb.) Schauer, B. micrantha Schauer, B. micrantha var. puberula Benth., B. orbifolia F.Muell., B. schaueri Preiss ex Schauer, B. schaueri var. (?) atrorubens Benth., B. sparsa R.Br. and B. squarrosa Schauer.
Tetratheca butcheriana (Elaeocarpaceae), a new and rare species from the Pilbara bioregion of Western Australia
PERKINS, A.J., REIFFER, S. AND AJDUK, H., Nuytsia 27: 203–209 (2016)
A new species of Tetratheca Sm., discovered while performing flora surveys along banded ironstone cliffs north-west of Tom Price in 2015, is described. It is named T. butcheriana A.J.Perkins in honour of Ryonen Butcher, a botanical researcher and well-published taxonomic expert on Tetratheca in Western Australia. This species is one of two species of Tetratheca geographically restricted to the Pilbara bioregion, both of which are of conservation significance. A taxonomic description of T. butcheriana is provided, along with photographs and a list of diagnostic features to aid in identification.
