group, however, not all speciespossess all the characters.Although none ofthe charactersis unique to the group, two of the more importantones, namely, spinosestipules ald medial peduncularbracts, are infrequent elsewhere in subgenusPhyllodineae-

1. Stipules.

Spinose stipules are seemingly presentin all members of the group, although in A. alemndri, A.apha ocladd aj|,dA.glaucocaesiarhey areratherpoorly developed. The stipulesare often prominent on youngplants but arecommonly absentwitl age. Onbiologically matue plantsoften only the stipule bascs rcmain ard are representedby a pair of blunt protruberancesat the base of the phyllodes; sometimeseven the protruberancesare lacking.

Spinose stipules occur elsewherein section Phyllodineae,but at a ratler low frequency, e.g. A.congestaBenth., A. paradom DC., A. xerophila W.Fitzg. They also occur in odrer sectionsof subgenusPlyl/odlreae, namely, the Alatae (A. alata R.Br-), Plurinemes (in A. unguicula Cowan & Maslin and at least thee undescibed speciesfrom W.A.) ar'd Pulchellae (A. anarthros MasIin and Arairii ssbsp.r ecunistipula Maslit\)- Spinosestipules occur in all speciesof subgenusAcacia (where they are often very well developed)but in subgenusAculey'erurz they areseemingly absent (although the stipulesat mature nodesot A. couryeriBerth. ex A.Gray from Mexico are somewhatspirose).

2. Peduncularbracts.

A minute bmct occus nearor abovethe middle of the pedunclein all speciesof the group; *re base of the pedunclesis ebracteate.Although this supra-basalbract is caducous(it is bcst observedon very young inflorescences)its scarcan usually be obsewedon at least some matureflowering peduncles of all speciesexcept A. aphanoclada.

Peduncularbracts are common elsewherein subgenusPlyllodineae but they are usually located at the base of the peduncle. Solitary bracts situatednear or above the middle of t}le peduncle are "A. uncommonbut do occur in a few speciesof sectionPlyllodi neaebesldcs lhe yictoride group", e.E. somemembers of the A. deltoideaEro\rp (lide Cowan & Maslir 1990),A. dentiferaBenth.,A. nodiflora Benth. Similarbracts occur al so in subgen:usAculeiferum (e.g. A. tamarindifolidWilld. nd A. paniculata Willd. from SouthAmerica) andin afew spcciesof subgenusA cacia(e.8.A. biacicularls S. Watsonand A. glandulifera S.Watson from Mexico).

"A. 3. Other charactersof lhe yictoriae" srouo.

"A. Speciesof the victoriae gro:up"are assigned to scctionPhyllotlineae on accountof their globular flower-headsand 4-nerved phyllodes. When the phyllodesare flat, which is the usual condition,there is a nerve along eachmargin and one on eachface; when terete (A. pickardii) the nervesre equatly spacedaround the lamina. The nervesare sometimessubmerged and thus seemingly absent.

Other characterscommonly encounteredin speciesof the group are the following: tall shrubsor smalltrees (except for A. ryaniana wlich is t prostrate);brarchlets oftenpruinose, glabrous (sometimes hary rnA.pickardii u\d A. victor iqe)', phyllode apices commonly irmocuous (pungentinA. aphanoclada, A. cuspidtfoliq,A. plc,tardii and sometimesA. delnpsteri);pedunclescommonly twimed, eitherwithin axils of phyllodes or along a racemeaxis, their baseebracteate: inJlorescences commonly initiatcd on onaotomnlS y g '"" ' (e{PIsnV 'pelcFlser) 't-S'I 'spr^\ ruelse \ lueururordlou quprur = / :l rurutl-r(S)'Suollur 9'Z-9'Isopo[.{qd:pore^\ou-oS-gtspeeH'6 'gg-g aDuolJt\,v'0I (pBardsepr.{)luau[uo;d raqle: quplu = .tr:1 'epr,,n '6 urur1y-7'Suoy ruc g1-g scpoyldqd :pcrc,^ oU-09-0Z spuag JopualssalJunped 'g :pere,roU-09>spEarl :o^oqE sEpomquoJ lou s.rtlJuJuqJapol,{q4 '" " DAJAID|J V t tsngor selcunped:pere.roU-06-09 spEeq:ueerE 'esruar-qns ol esnlar'3pl\\ urru (tE)SZ-OI sapofl.{qd '8 Suoyuur g1-9 selarmped:asouacer fpueuluopa:il '/ ro IF,{ll€nsn se3ueJserouxr:,rollaf, elBdot ot$.r FuEerc speeH 's (8uol ruc t> uer{lr?aull Jr) o^oqu sBlou sopoll,{qd " " " " ""-" 'polJulsar) upumap V'I (BIIBISnVuralsal& apl^\ unu 8-t '9 saum8al:asoum?r lou saJuecserol]ur:pEeq €d 08-09 sJe^\ol{ 'o1" aDuo|slnv (ppeJdsaplr)opr,r ruru 9I-6 saum8al:asoruaJuJ '9 ,{1}ueururoperdro IIB secuacsorouxr:pEeq red O'-SI sre/dolC 'g unerr spEar{:8uolruJ t< IIB Io aruosONv JBeull+ sepoll.{qd JlelnuorJnu,{luoLuLuo.:'snonJolrul sJpolL,{r{d f lDJrdwdP V s ueploS speeq 'e1e1oecur1 :8uol ruru t> dsnc f,1.tro:reuol alplooJuBlsepo[dqd t o4oltpdsn y y ''"" .,'rol1adapd sp?eq:8uol 'elEloecuBlqo-Suolqo urur Z-I dsnc f,l/..orrcuol JEaurlsepo[.{qd i leIJ sepolldqd € '" 't np.tDlJrdV'L eleral sopoll.{qd 'Z tue8und sepoll.{qd .I 3uo1ucA1> sapo11fq4 .I DpDpouDIdDV'Z Euolruc A1< sapo11dq4

Distribution. Norlh-westWe stem Ausl-Ialiainthe Camarvon BotanicalDistrict(1:250,000mapsF49-12, F50-9). Known only from a few localitiesin the CapeRalge. llabirat. Pinkish brown loam on rocky limestoneslopes in Open Shrub Mallee over Low Scrub and Spinifex (Trlodia spp.).

Consenalionstatus.2RC-accordingtothecdteriaofBdggs&Leigh(1988).Of tlle few collections lcrown, about half occur within the CapeRange National Park.

Flowering period. Mostly August-Septcmbel onc collection in June.

Fruiting period. Legumes with maturc sccdshavc bcen collected in late October.

Affinities. Closely alliedto the widespreadspecies, A. yictoriae,but distinguishedby flowers 60-80pcr head, inflorescencesinitiated on new shootswith 1-4 pedunclesarising within the axils of the young phyllodes,legumes7-8 mm wide, seedsnot mottled,funicle slender,and phyllodesusually longer. In Westem Australia the phyllodes of A. yictoriae are generally 2.5-4 cm long and not often linear. However, in the Kimberley region (andalso in Queensland)some specirnens ofA. r,ictoridehayelil')ear phyllodesto about 10 cm long but thesecan be distinguishedfrom A. alexandriby tlle othercharactcrs " given above. Arother widespreadmember of the A. yictorise gtoup", A. synchronicia,grows near A.alexandri ir the CapeRange but is readily recognisedby its much shofterphyllodes (c. 2 cm long) and golden flower-heads.

Elynalogy. Named after AlexanderS. Georgewho discoveredtlte speciesin 1960. Prior to becoming Editor of the Flora of Australia in 1981, Alex was employedfor 21 yearsat the Westem Ausfaliar Herbarium. He has made significant contributionsto the botany of Westem Australia through his numerouscollections (e.g. almost800 Acdcld gatherings)and publications.

Dense,glabrous shrubs or trees 2-6 m tall. Brd chlets terete, obscuely ribbed, conspicuously pruinose.Sripules presumably spinose on youngplants(see yadaliorbelow) but onlytheminute, blunt basespersisting as toothlike projectionsat nodcson matureplants. Phyllodes elliplic to narrowly elliptic or lanceolate,sometimes obovate to oblong-oblanceolate,rounded to obtuse,1.5-2.5 cm long, (5)7-13 mm wide, 1:w = 1.5-3, thin, glaucous,rarely green except on new gronth, midrib not prominent, obscurelypenninerved. G/dad situated on uppermargin ofphyllode at distalend ofpulvinus, not oyerly prominent,c. 0.5 mmlor'g. Inflorescence,Jmost commonly racemosewith somepeduncles subtended by sccondaryphyllodes as in A. victoriae, sometimesa few simple and initiated on new shootsas it A.synchronicia,both tlpes may be presenton a single plant. RacemesI-6 cm long, axes slender, ebracteateat base, Pedunclesmostly twinned, 7-10 mm long, slender,base ebracteate; bmct above middle of peduncle caducous(bract scar visible on mature peduncles). Flower-heads showy and prolific, globular,small,4mm diam. (whendry), pale yellow, densely35-50-flowered. F/owers 5-merous. Sepal.rfree, narrowly spathulate.Perals 1-1.4mm long, nerveless.Legumes raro\aly oblong,to 4 cm long, 10-13mm wide, chartaceous,flat, rourded over seedsalong midline, modcratelypruinose. SeedJ trarsverse,oblong to ovate,4.5-5mm long, 3-4 mm widc, slightly shiny,brown to blackish,sometimes "U"-shaped, very obscurelymottled; plcurogram not prominent;areole c. 0.5 mm long, opentowards the hilum; funicle short,thick, cream,scarcely adllate.

Distribution. Norll-west Westem Australia in the Fortescueand (western extremity o0 Canning B otanicalDisl.ricts (1:250,000mapsF50-2,4,6). Known only from afew scatteredlocalities in thewestem pafl of the Pilbara region betweenthe Fortescueand De Grey Rivers. A vaJiantfrom Salt Creek (851-13) is discussedbelow.

Itabitat, Sandyloam on flood plains;commonly forming almostmonospecific stands.

Flowering andfruiting period. Flowers late July-September.Legumes mature from late Octoberinto November.

Synonymy.In describingA. g/abriflora Maiden andBlakely must havebccn unawarcthat Domin had alreadypublished the nal;'teA. glaucocaeJiafor the sametaxon sometwo yearspreviously. Not only did Maiden & Bla.kelybase their nane on the sameE.E. Clement collection as was used by Domin (seeminglyusing different specimens)but they also adoptedan epithetthat Domin had usedfor quite a different speciesin 1926.

Variation. The following vegetativespecimen is tentativelyrefened to A. glaucocaesia:Salt Creek, 27 km due E of Great Northern Highway betweenPon Hedland ard Broome, 19" 44' S, 121" 28' E, B.R.Maslin4814?ERTH).

Distribution. Westem Australia in the Dampier, Hall, Fitzgerald, Mueller, Fortescue,Keartland, Camarvon, Ashburton and Austin B otanicalD istricts ( 1:250,000 maps E5 I -3,7,8,12,14',852.-9 ,10,14;' F50-12,3,4,5,6;7,9,10,11,13,14,15,16;F51-1,5,6,9,10;G494;G5O-1,2A,5,6;7,9,11,15;H50-2).Commonin north-westernW.A. from SharkBay north to Port Hedlandand eastto the Rudall River. Also common in the southernKimberley region from near Fitzroy Crossing east to the W.A./N.T. border. (It is probablethat future collectionswill extendthe range of the speciesto at least the westem part of the Northern Territory.) Isolated occurrencesare recorded from the Robinson and Logue Rivers (westernKimberley), Nita Downs Station (betweenthe Pilbara and Kimberley regions) and the Cue- Yalgoo area,c. 350 km south-westof SharkBay.

H abitat. W atercorJrsesand alluvial flats in oftenrocky (limcstone,quartz) sald, clay or loam. Sometimes on rocky hills but then usually along drainagechannels or in clay,4oamdepressions. Commonly very abr.ndantin places where it occurs.

Flowering period. August-December,

Fruiti g period. Legumes with mature seedshave beencollected in January,April, May, November and December.

Variation. The phyllodcs ofA. synchronicia v ary corsiderablyin shapeand size(particularly in width) with the variation appcaringto be continuous. Usually they arenarrowly oblong to narrowly elliptic or nanowly oblong-oblanceolate,3-8 mm wide, l:w = 3-7 and the seedis mottled and 4-5 mm long. Specimenswith l linear,especiallynarrowphyllodes (1-3 mm wide,l:w= 10-14)and +non-motded,black sceds3-4 mm long arecomrnon in the RudatlRiver area(e.g.B.R. Maslin2M6, &207 6, M.Mclnnes s-n-, A.S. Mitc hellT24 andP .G.ll ilson 1O293)and at a few scatteredI ocalities in fte Pilbararegi on, e.g. B arrow Islnd (R.Butkley 6952),near Shay Gap (L.ThompsonLXT 1180). This nanow phyllodevariantwhich wascalledA. aff. viclorlae in Maslin (1981: 131)may ultimatelybe shownto warantformal rank. Plants "llpical" of A. rynclro icia alsooccw at the Rudall Rivcr (e.9.B.R. Maslin2053 and 2053a) a-ndtlese havephyllodes which areelliptic to narrowly elliptic and 5-8 mm wide.

Two sterilespecimens (B.R.Ma,r/in 5000 and 5267) withunusuallybroad, ellipticphyllodes (8-13 mm wide, 1:w = 2-3) and pruinosebranchlets resemble A. g/alcocaeJidbut areincludedtn A. synchronicia becausethe phyllodes are fleshy (finely wrinkled when dry) and have a prominent basal gland.

Threc spccimensfrom the west Kimberley region which appearto rcpresentthe sameentity are unusual, They have tlinner than normal phyllodes and, accordingto thc label on one of them, have pale yellow flowers (a characterof A. victoriae).

HaDitat. Arid andsubhopical areas in avariety ofhabitatsbutcommonly in clay or loam on alluvial flats, also tespeciallysubsp. arida) in sard.

Vqriation. Acdcia victoride is quite a variable species. Its inflorescencesare usually long, slender, determinate racemes with a profusion of heads so that at anthesis the plants are very floriferous "leafy" Sometimesa few racemesmay become through the developmentof a secondaryphyllode at the baseof someof the (usually twinned) peduncles, In thesecases lle specimensshow a mixture of racemesand simple inflorescenceswith the former usually occurdng in greaterabundalce. Only very rarcly haveI observedthe inJlorescences o\ A.rictoriae tobe all simple,being initiated on new shoots witlr 1 or 2 pednnclesarising from within axils of developingphyllodes as in A. rynchronicia-

The phyllodes aJequite variable as noted in the descdption above. According to Pedley (1980) the phyllode penninervationis prominent on specimensfrom nortl-west Qld. Elsewhercthe lateral nervation is not prominent or even seeminglyabsent.

The taxonomicstatus ofA. vicloriae subsp.arlda requiresfurther inyestigation.Specimens asffibed to tlis taxonhavedensely tomentose bralchlets andphyllodesand occur on sandysoil in southemN.T., northernS.A., westemN.S.W. andsouth-westem Qld. Hairy branchletsandphyllodes occur in typical A. yictoriae b the indumentum,especially on the phyllodes,is usually sparse. Intermediatesoccur between the two subspecies.

A. yictoria€ subsp.arida Pedley, Austrobaileya 1: 271 (1980). Type: Poeppel Comer, Sept. 1966, D. Boyland254 (holo: BRI, n.v.; iso: K, n.v.). (Figure7K) lA. brachybotrya auct.non Benth.: L. Pedley,Contr. QueenslandHerb. No. 4: 6 (1969)1.

Acaciaglaucocaesia(W.A.)mayultimately be shown to be conspecificwith A. victoriae. F.cferto the above-mentionedspecies for discussion, tltilization- Moderatenutritivc value and a useful stockfood supplementduring droughts. Useful as a low windbreat and for soil stabilizationin dry country. Numbers may increasemarkedly during a successionof wet seasonsald can become a nuisance,especially around watering points. Fodder potentialand other uses are discus sed in Everest( 1969), Askew andMitchel I ( 197 8), Rachie et al . (1979) , Hall e/c/.(1981) and Tumbull (1986).
