THREATENED SPECIES SCIENTIFIC COMMITTEE Established under the Environment Protection and Biodiversity Conservation Act 1999 The Minister deleted this species from the vulnerable category effective from 16 September 2015. Listing Advice Bosistoa selwynii Taxonomy Bosistoa selwynii is a species of bonewood or satinwood that was described as being unifoliolate (having one leaflet) (Hartley, 1977) whilst other Bosistoa species have some leaves on the plant with three or more leaflets (Hartley, 1977; Richards, 1991). Defining characters of B. selwynii have been found to be insufficient to maintain it as a species and it is now placed in synonymy with B. transversa (Richards, 2002; Hartley, 2013). Bosistoa selwynii is now excluded from the Queensland flora census (Queensland Herbarium, 2013) and the New South Wales flora census (The Royal Botanic Gardens and Domain Trust, 2014). Bosistoa transversa is listed as vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and vulnerable under the Threatened Species Conservation Act 1995 (New South Wales). Reason for conservation assessment by the Threatened Species Scientific Committee Bosistoa selwynii is listed as vulnerable. This species is eligible for listing as vulnerable under the EPBC Act as, prior to the commencement of the EPBC Act, it was listed as vulnerable under Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth). This assessment is due to current information on Bosistoa selwynii, stating the species is no longer considered a valid taxon. Public consultation Notice of the proposed amendment and the reasons was made available for public comment for 46 business days between 24 November 2014 and 30 January 2015. No comments were received. Assessment of available information in relation to the EPBC Act Criteria and Regulations and consideration for delisting As identified in the taxonomic discussion provided above, Bosistoa selwynii is no longer considered to be a valid taxon and is not eligible for listing in any category. Consideration for delisting As Bosistoa selwynii is not considered to be a valid species, delisting is not expected to have any negative impacts. Recommendations (i) The Committee recommends that the list referred to in section 178 of the EPBC Act be amended by deleting from the list in the vulnerable category: Bosistoa selwynii The Committee notes that this species is eligible for delisting due to taxonomic change.
