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.
