Ianuginosaspecies complex is found from King Sound(WA) to Wollogorang(NT) (Figurel) andconsists ofan uncertainnumber oftaxa. Morphologicalvariation within the complex is analysednumerically, using phenetic methods. Leafanatomy and ontogeny, and the taxonomic status of thefour availablenames within thecomplex (vL. B. afinis, B. evtenisifolia,B. artemisiifoliavar. wilsonii,and B. Ianuginosa)are discussed. TheB. flicifolia speciescomplex is endemicto theKimberley Region and consists offour species thatare morphologically and geographically distinct. Wheeler (1992) recognized a numberofforms withinB. Jilicifoliatncludingthe Mitchell River (and t5.pe) form and a Kalumburu form (8. kalumburuensis, seebelow). A third form,from the OsmondPlateau, is describedbelow as B. minutipinna.Boroniq pauciflorais alsoplaced in thisspecies complex (Duretto 1995; Duretto & Ladigesin prep.). Thethird speciescomplex consists ofthree rare species, B. decumbens (NT), B. jucunda (W A) and, B. tolerans(NT),that are newly described below. To completethe revisi.on of Boroniain theNorthern Tenitory and the Kimberley Region, taxa are lectotypifiedwhere necessary (including B. lanceolata)and B. rupicolais d.escribedasnew, Boronia lanceolataandB. ruprcolaare more ciosely related to eastcoastmembers ofBolonia sectionValyatae thanto otherspecies in north-westernAustralia (Duretto 1995; Duretto & Ladigesin prep.).At thefinal stagesofmanuscriptpreparation a 1995 collection (l R.C/a/ kson 1047 3) fromnorth -west Queensland, nearthe NorthernTeffitory border, came to the authors'attention. The specimen is of a previously unknowntaxon that has affinities with B, alulataBenth.of CapeYork (Durettosubmitted; Duretto & Ladigesin prep.),and so will bedescribed in a forthcomingpaper that deals with Queenslandmembers of Boroniasection Valvatae (DuretIo submitted). As thisspecies is sympatricwith B. lanceolata(in Queensland)itwilf beincludedin thekey as Boroniaaff .alulqta(NWQld, C/artro n10473). AllBoronia speciesfound in theNorthemTerritory, the Kimberley Region, and north-west Queensland are placed in section Valvatae. TheNorthern Territory and Kimberley floras are treated here as a single unit for anumberofreasons. Firstly, apart frorn B. lqnceolqtaand B. rupicola, cladisticanalysis shows that all taxa form a monophyleticgroup defined bythe following synapomorphies: the calyx being as large as or largerthan the corolla,the antesepalousanther being significantly smaller than the antepetalous anther, and the filamentshape (Duretto 1995; Duretto & Ladigesin prep.).Secondly, the boronias ofthis regionare widely separatedfrom the eastcoast, South Australian, and south-west Westem Australian members "Top of Valyatae.Thirdly, and finally, the region covering the End"ofthe Northern Tenitory and the Kimberleyregion is oftenrecognized as being a distinctbiogeographic region or a numberofclosely relatedregions; that is, regions that share arecent history (see Specht 1958b;Kikkawa & pearse1969; Hnatiuk& Pedley1985; Cowie &Finlayson 1986;Cracraft 1991;Dunlop & Webb 199l.,Crisp eta\,1995 Duretto1995; Duretto & Ladigesin prep.). The boundariesfor thesebiogeographic units, at leastfor Boronia,rotghly correspondto the boundariesofthree geological basins(as outlinedby Plumb& Derrick 1975;Plumb e/al 1980;c.S.W.A. 1990):the McArthur fuver Basin which extends liom Mtlsa(north-westQueensland)totheArnhemLand Plateauand surrounds (northem andwestemNT);the VictoriaRiverBasin, especiallythenorth-western heavilyfaulted area, which includes an area liom thewestemNorthemTeritorytotheOrdRiver(WA); and,the Kimberley Basin includingthe neighbouring King Leopold and Halls Creek orogens ormobile plates.These basins are characterized by Precambriansandstones. : Sutpnlcur),{rollueluequoNoqgoseel€utalspepueulsquoueq}uto{pslcsllocslueld.oBuerslrssoJr€ .g uolleu€AIsJoLl pue IecrSoloqdrour euos sx,ot1s osou 6nuo 1 uorteueArunlueurnpur srql qlr,r Buoly '1sadeql ur uolsnJuoccrruouoxq eulos ol ,sa^ecl pel seqsrql suudqlu€ued er{tJo ao€JJns I€txgqe aq1 uo lueserdosle sr eqtuo sJtuqJo,(lrsuop 'setlrsuap ',{l8urlsolalul .stu!//b eql qlt,t pel€louoc ,{llEnsnst qorq,r ;req3o e8uet u g sE peu\u-tapp ,npet€ld uouoerg leql pucrunluaLunput esJuds s o,ruqro snorqulSaru leqt slueld lleusgo lsrsuo, pu?.1 uequrv equo rlyou sureldpues eqtpue (errelued.ru3jo;1n9) puulsl quoN,(Uud Ituop€N npul€)) searu Mopes'qlhlpueIlrqeJthleql ur osoql s€ qcns,suoqelndodreqlo.(vzg_zzs:vno;-to;:'I6v_ggv:IBn_LLv '3 oTlatnq e) ssaualns.rrqjoseer8ep 3ur,&B^ ,{Eldstp l€q} suroj e1rye33o f1arre,,iu uruluocsuotlrlndod ,larct3 ,.ggptr fuu11 ecuenbescrloueSoluo srql ^sldsrp (LZZ ul1tDry 6>a!or14 tr>y1g1 uowlq&11 '9 '.OB9l L\t'SZ\EqtDauuax llDLlsuaH'.8VgtlaS.roaD:OOg ojptn1:OBt; dopne 3 a)sueurceds auog '( '166 derdur 1se8rp€-l ? ollelnC:S 661oltalne)app^lo/l uorlf,esJoslequroLu lorllo ul po^tesqoueeq suq 'urnlueunpul sE elellolsesuep D SurAeq se^Eel ol 'unluaunput el?llolspuu aldlllts esreds e q1r,{\sa,real 'seluel ro snorqelSuor; luorudole^opJucl ur acuenbasclloueSoluo uu seyosou8nuol oruotog '( 1ernBrg) (151) uorluls SusJoSollolA ol (V,44)punos Suty tuo.t1puo;dsepr,r puu uoruuroosr (peqrrcsu;ncrrr,{1lue.uncsu) psontnuol g 0lrq,r(066t)nrleuH:[966t q8ra] ?s33ug urpolsr l ]oul 886 I q3la1? s33ug),4rotr.eJuroLiuoNaqlo] peuguoopua'pe:e8uepua,(lqrssod'o:ereqotperoplsuo.sl.r/u(Jboruo.tog.,4.ro1rrra1ureqyo51eq1ur 'suorlJelloc crrledrufsere rsonrBnuq g puestu(/b B puuspJoco; unrJeqtaq lursa:d ruo:.p 3ul3pn1 'sauuuo,rl esoqlJouorlucr;ddu eql SurpunornsuorsnJUoc qcnusreraqJ unluaunpul esuepE seqDsout8nupl B elrq,r unluounput esludsu sBqJo snoJqulS sl .t0-Z0g stutjgbg $tltslosou!3nuo1 g wotSstullJb.g qsrnSurlsrpo1 pasn ueoq seq lpql ernl€eJur€tu eql I ur ,;oleir1sa,ru1aq1-, uo lan€g puuurpJOCpu€ slepurlC ,reqllu t{ qll^\ Bullle^€llollr.lM u,ro.lg uoqoU ,{qpetca;1oc sa.,n (,,tpuDl,{A oloorD olrsoddo puuluru ur puu 'erle1uedru3; o;1n9 equo spuplsl.urlcrlsnV 'N) s!uW g3o 1er.releur ed,{1 aqJ urlcrtsnv ulolsa,r-q ou ruol.}(rr.rorBnuDl B tepunpe u,{uoufs {llueserd) laosTral sur,ot1o1fuxwa1to g puu otlolrcrl{ .g .s1u11!Jbg peqrrcsap(g9g y) ruuqtuog '(S/61uoslr/A) lu€goptlts g sEu,f'ouT ^\ou st osout8nuol A pallEc ueaq,{lsnor,rerd peq tuql satcedsuerlerlsny u.talsalduJotso^\-qlnos eqI 'lueunfup '( .g s,uoslr/A SurueqlSue:1s urruoc s:eduos116) aso uBnuol tro 1tl,talutuod,{l eql ol Iscrluopr ,slspurlJ eJulBql ErJ€luetuEJJo.]lnD oqlJo spu€lsl oql ulo.Usueullceds tupld pelcelloc pulltone8 qll,r ,;o1e8rlse,ruJeq1,, uo se^\oq,r'u,roJB ueqod e8uroApuocas slr uo pollo^u! peq,,ro1e8r1se,,ru1 eq1,, dtqs, s:apur;g e:eq,tr pus.l uo qu.lVJolsuoc oql uo olaq,reuo s seMosoulsnuq g

  • Journal of a Voyage Around Arnhem Land in 1875
    JOURNAL OF A VOYAGE AROUND ARNHEM LAND IN 1875 C.C. Macknight The journal published here describes a voyage from Palmerston (Darwin) to Blue Mud Bay on the western shore of the Gulf of Carpentaria, and back again, undertaken between September and December 1875. In itself, the expedition is of only passing interest, but the journal is worth publishing for its many references to Aborigines, and especially for the picture that emerges of the results of contact with Macassan trepangers along this extensive stretch of coast. Better than any other early source, it illustrates the highly variable conditions of communication and conflict between the several groups of people in the area. Some Aborigines were accustomed to travelling and working with Macassans and, as the author notes towards the end of his account, Aboriginal culture and society were extensively influenced by this contact. He also comments on situations of conflict.1 Relations with Europeans and other Aborigines were similarly complicated and uncertain, as appears in several instances. Nineteenth century accounts of the eastern parts of Arnhem Land, in particular, are few enough anyway to give another value. Flinders in 1802-03 had confirmed the general indications of the coast available from earlier Dutch voyages and provided a chart of sufficient accuracy for general navigation, but his contact with Aborigines was relatively slight and rather unhappy. Phillip Parker King continued Flinders' charting westwards from about Elcho Island in 1818-19. The three early British settlements, Fort Dundas on Melville Island (1824-29), Fort Wellington in Raffles Bay (1827-29) and Victoria in Port Essington (1838-49), were all in locations surveyed by King and neither the settlement garrisons nor the several hydrographic expeditions that called had any contact with eastern Arnhem Land, except indirectly by way of the Macassans.

  • A New Freshwater Catfish (Pisces: Ariidae) from Northern Australia
    Rec. West. Aust. Mus. 1988,14(1): 73-89 A new freshwater catfish (Pisces: Ariidae) from northern Australia PatriciaJ. Kailola* and Bryan E. Pierce* Abstract A new species of fork-tailed catfish is described on the basis of 31 specimens collected in northern Australia between the Fitzroy River (Western Australia) and the Mitchell River (Queensland). Arius midgleyi sp. novo grows to at least 1.3 m TL and is distinguished from other Australo-Papuan ariids by a combination of charac­ ters including snout shape, barbel length, eye size, tooth arrangement and gill raker number and position. Comparison is made with other ariid species occurring in northern Australian rivers, including the morphologically similar A. leptaspis (Bleeker). Introduction The Timor Sea and Gulf of Carpentaria drainage systems (Lake 1971) approx­ imately represent the Leichhardtian zoogeographic region of Whitley (1947). The rainfall pattern in this region is dominated by the wet monsoon (occurring within the period November to April). Most rivers here traverse a flat coastal plain about 15 km wide before reaching the sea (Lake 1971). These rivers commonly possess wide flood plains and low gradients, often contracting to a chain of waterholes during the dry season; some (Gregory River; Fitzroy to Daly Rivers) have reaches of rapids or very deep gorges. The average annual discharge from this region is 69000 billion litres (Lake 1971), most of it occurring during the wet season. Five of Australia's 18 species of fork-tailed catfishes (Ariidae) are common in this northern region, yet were overlooked by Whitley (1947) and Iredale and Whitley (1938). The members of this family, which is distributed circumglobally in the tropics and subtropics, may inhabit the sea, rivers within tidal influence, or fresh waters.

  • Transporting Melbourne's Recovery
    Transporting Melbourne’s Recovery Immediate policy actions to get Melbourne moving January 2021 Executive Summary The COVID-19 pandemic has impacted how Victorians make decisions for when, where and how they travel. Lockdown periods significantly reduced travel around metropolitan Melbourne and regional Victoria due to travel restrictions and work-from-home directives. As Victoria enters the recovery phase towards a COVID Normal, our research suggests that these travel patterns will shift again – bringing about new transport challenges. Prior to the pandemic, the transport network was struggling to meet demand with congested roads and crowded public transport services. The recovery phase adds additional complexity to managing the network, as the Victorian Government will need to balance competing objectives such as transmission risks, congestion and stimulating greater economic activity. Governments across the world are working rapidly to understand how to cater for the shifting transport demands of their cities – specifically, a disruption to entire transport systems that were not designed with such health and biosecurity challenges in mind. Infrastructure Victoria’s research is intended to assist the Victorian Government in making short-term policy decisions to balance the safety and performance of the transport system with economic recovery. The research is also designed to inform decision-making by industry and businesses as their workforces return to a COVID Normal. It focuses on how the transport network may handle returning demand and provides options to overcome the crowding and congestion effects, while also balancing the health risks posed by potential local transmission of the virus. Balancing these impacts is critical to fostering confidence in public transport travel, thereby underpinning and sustaining Melbourne’s economic recovery.

  • Extending Out-Of-Home Care in the State of Victoria, Australia: the Policy Context and Outcomes
    Scottish Journal of Residential Child Care Volume 20.1 Extending out-of-home care in the state of Victoria, Australia: The policy context and outcomes Philip Mendes Abstract In November 2020, the State (Labour Party) Government of Victoria in Australia announced that it would extend out-of-home care (OOHC) on a universal basis until 21 years of age starting 1 January 2021. This is an outstanding policy innovation introduced in response to the Home Stretch campaign, led by Anglicare Victoria, to urge all Australian jurisdictions to offer extended care programmes until at least 21 years. It also reflects the impact of more than two decades of advocacy by service providers, researchers, and care experienced young people (Mendes, 2019).

In June 2019, there were nearly 45,000 children in OOHC nationally of whom the majority (92 per cent in total) were either in relative/kinship care or foster care. Only about six per cent lived in residential care homes supervised by rostered staff.

  • Volcanoes in SW Victoria & SE South Australia
    Volcanoes in SW Victoria & SE South Australia June 2005. The volcanic plains of western Victoria form a belt 100 km wide which extends 350 km west from Melbourne nearly to the South Australian border. In addition, several volcanoes occur near Mt. Gambier. The gently undulating plains are formed of lava flows up to 60 m thick, and are studded with volcanic hills. About 400 volcanoes are known within the region, which has been erupting intermittently for the last five million years. The youngest volcano appears to be Mt. Schank, in South Australia, which erupted about 5,000 years ago. The Aborigines would have watched this and some of the other eruptions, and they have stories of burning mountains. Further eruptions could happen, but are not likely in our lifetimes. Volcanoes erupt when molten material (called magma, in this state at about 1200°C) is forced up from great depths. On reaching the surface this may flow across the ground as lava, or be blasted into the air by gas pressure to build up cones of fragmentary material (including scoria and ash). Most of the local volcanoes erupted for only a few weeks or months, and never again – the next eruption was at a new site. In the Western District there are mainly three types of volcano, though combinations of these also occur: About half of the volcanoes are small steep-sided scoria cones built from frothy lava fragments thrown up by lava fountains. A group of about 40 maar craters near the coast were formed from shallow steam-driven explosions that produced broad craters with low rims.

  • Australia's System of Government
    61 Australia’s system of government Australia is a federation, a constitutional monarchy and a parliamentary democracy. This means that Australia: Has a Queen, who resides in the United Kingdom and is represented in Australia by a Governor-General. Is governed by a ministry headed by the Prime Minister. Has a two-chamber Commonwealth Parliament to make laws. A government, led by the Prime Minister, which must have a majority of seats in the House of Representatives. Has eight State and Territory Parliaments. This model of government is often referred to as the Westminster System, because it derives from the United Kingdom parliament at Westminster. A Federation of States Australia is a federation of six states, each of which was until 1901 a separate British colony. The states – New South Wales, Victoria, Queensland, Western Australia, South Australia and Tasmania - each have their own governments, which in most respects are very similar to those of the federal government. Each state has a Governor, with a Premier as head of government. Each state also has a two-chambered Parliament, except Queensland which has had only one chamber since 1921. There are also two self-governing territories: the Australian Capital Territory and the Northern Territory. The federal government has no power to override the decisions of state governments except in accordance with the federal Constitution, but it can and does exercise that power over territories. A Constitutional Monarchy Australia is an independent nation, but it shares a monarchy with the United Kingdom and many other countries, including Canada and New Zealand. The Queen is the head of the Commonwealth of Australia, but with her powers delegated to the Governor-General by the Constitution.
