This result is consistentwith the findings of and watson (1975) and indicaie that it is unlikely the Alatae or continuae will be recognizedas formal, higher-ordercategories in future classifications. "phyllocladinous There are six speciesincluded below under the heading taxa". Although these speciesall have decurent phyllodes that lbrm prominent,opposite wings along the stemsihey are not all closely related to one another. Acacia bifaria sp. nov. and its close relative A. glaucopterq Benth. difrer significantly from the others,particularly in carpologicalfeatures; these two speciesare related to the A. merraLlii F . M'ell . groupwhose members do not have winged stemsand only rarely have decurrent phyllodes. Acacitl applanata sp. nov. is closely related to A. willdetlowiena H. wendl. and taxonomicallynot far tiom A. alqtaR.Br. The preciseaffinitie s of A. pterocdulon sp. nov. are not a)togetherclear. Bentharn's( 1864)classification included three species where the phyllodes were reduced to scales; thesewere incfudedin seriesPungentes subseries AphylLae Benth, (A. spinescensBenth.) and series calamlfurmes subseriessubaphyllae Benth. (A. tetragonocarpaMeisn. and A. restiacea Benth,). Neither ofthese subserieshas been recognized in the recentclassifications of,4c acia and there areno indications that aphyllodinous taxa (of which there are about five now recognized) represent a monophyletic group. "Aphyllodinous of the five speciesincluded below underthe heading taxa" only A. cummingiana sp nov. has all its phyllodes reducedto horizontally flattened scales (like those found in A. tetragonocarpd). It seemslikely that in thesetwo speciesat leastthe scalesare homologous to fused phyllodes and stipules(see note underA. cummingiana). wh)le A. aemula sp.nov. has for the most part normal phyllodes (which closely resemblethe branchlets)a few terminal ones are sometimes reducedto horizontally flattenedscales . rn A. carens sp,nov. and A. cerastessp. nov. the phyllodes are very rudimentary and are representedby minute, stipule-like or horn-like projections, Acacia volubilis F. Muell., which like A. aemula has distant, normal phyllodes which resemble the branchlets,is included within this group for comparativepurposes because the name had until now commonly been misapplied to some of the new speciesdescribed in this paper. Methods The taxa included in this paper are a'anged alphabeticallyunder two headings,phyllocladinous taxa and Aphyllodinous taxa.

  • Conservation Advice: Acacia Meiantha
    THREATENED SPECIES SCIENTIFIC COMMITTEE Established under the Environment Protection and Biodiversity Conservation Act 1999 The Minister approved this conservation advice and included this species in the Endangered category, effective from 11/05/2018. Conservation Advice Acacia meiantha Summary of assessment Conservation status Acacia meiantha has been found to be eligible for listing in the Endangered category, as outlined in the attached assessment. Reason for conservation assessment by the Threatened Species Scientific Committee This advice follows assessment of information provided by New South Wales as part of the Common Assessment Method process, to systematically review species that are inconsistently listed under the EPBC Act and relevant state/territory legislation or lists. More information on the Common Assessment Method is available at: http://www.environment.gov.au/biodiversity/threatened/cam The information in this assessment has been compiled by the relevant state/territory government. In adopting this assessment under the EPBC Act, this document forms the Approved Conservation Advice for this species as required under s266B of the EPBC Act. Public consultation Notice of the proposed amendment and a consultation document was made available for public comment for 32 business days between 16 August 2017 and 29 September 2017. Any comments received that were relevant to the survival of the species were considered by the Committee as part of the assessment process. Recovery plan A recovery plan for this species under the EPBC Act is not recommended, because the approved Conservation Advice provides sufficient direction to implement priority actions and mitigate against key threats. The relevant state/territory may decide to develop a plan under its equivalent legislation.

I did not attend the Conference, but would like to Note: If you wish to view or download extend our very sincere thanks to John Boevink for previous Study Group Newsletters, they are organising our Study Group display.
