We havealso benefitedfrom accessto recently acquireddata on allozyme and DNA markers. The early history of the systematicsof south-westernAustralian orchids is reviewed here. It comprisedtwo phases:(1) the first encountersby Europeansand (2) the early colonial phasein which James Drummond was prominent. The strong reliance of taxonomists on the collections and observationsof interestedrcsident orchid enthusiastsis a recunent featureof this history, Our taxonomic conceptsfor genera,species, subspecies and hybdds are described. New taxa are consideredto be speciesif they grow in populations(i.e. are not aberrantindividuals within normal populations),if they have featuresor a combination of featuresnot seenin any previously named species,and especially if they grow with previously named speciesand produce few or no natural hybrids. Geographicalraces with minor morphologicaldifferences are recognized as subspecies. These may hybridize and intergmdeextensively where their geographicalranges overlap. Our emphasison biological as well as morphological attdbutesin recognizingspecies and subspeciesis a significant changeftom past practice. It leads to the recognitionof more specieswithin complexespreviously treatedas single polymorphic species(e.g. Caladeniafilamentosa R. Br., C. huegelii H.G. Reichlt.)- Thereare many practical advantages toourapproach, includingimproved management forconservation, improved cultivation, and more precisecommunication and conductofpopular and scientific studies on south-westemorchids. Nevr'genera, published elsewhere,are basedon numerical analysesof morphologicaldata, aswell asthe recently completed DNA sequencestudies ofKoreset al. (20O0,2001\. Introduction Two centuriesago, Archibald Menzies,surgeon and naturalistaboard the ILMS. Discovery, was the first European to make collections of Western Australian orchids. The Discovery, under the commandof CaptainGeorge Vancouver, was anchoredin King GeorgeSound from 28 Septemberto 11 October1791. "copious Menzies made a collection of ... yegetableproductions, principally the genusBantsia, which are here very numerous" from various sites onshore in the vicinity of present-dayAlbany (Maiden 1909; Heberle, undated). Three orchid specieswere subsequentlynamed from Menzies' specimens,including one bearinghis name-Leptoceras menzt€stt(R. Br.) Lindl., Caladenia flavaR. Br. andDiuris longifulla R. Br. (Brown 1810;Lindley 1830-1840). The presentseries ofpublications, basedon more than two decades'research, contdbutes towards the celebrationof the bicentenaryof Menzies' pioneeringcollections. Here,we provide a genemlintroduction to the series,and a new key to genem of south-westernAustralian orchids. South-westemAustralia is one ofthe few regionsin the world where the abundanceand diversity of terrcstdal orchids may be breathtaking (Hoffman & Brown 1992, 1.998). In some habitats, particularly the first spring after a fire, more than 40 specieshave beenrecorded in a few hectares,in somecases so abundantthat walking without treadingon them was impossible. But such situations are exceptional. Indeed, most residentsand tourists, professionalbotanists among them, overlook orchidsand underestimate the dch diversity found in the south-west.There are several reasons for this. e roJ 966I osrJJ oes)lsluEtoq unlrPqroq eql ol lsol eJPsJelcsJeqc cruouoxel AuEr! lEql sueurlJeos 3ur,{rp puu Surssard,{q pe olsrp os sr sprqcJoruolse^\-qlnos Jo Jnopo pus .rnoloJlrslep IeJnpruls 'sueupeds eqlJo qsnl{ unrJeqJeqIsuorlue^uor qlr^{ dluo ?u1pepur sruolqordclluouoxEl eruocre,ro fypquelsqns e,req suorlelndodprqJJo ur uolleue^ Surdpnls o1 seqceo:dde^\au'{lpuoros puv '(polepun '? e3:oag ry slueurelJ e) sJeqcruaserpuorsse;ord 'splr{Jro pw stsersnqlueprqcro uaa^leq uorlrerelq qql petellllJ€JJaqunJ seq Jo ,{pnlsrrJrluarrs pus uope,rgpc eql Surloruordo1 pelecrpep ,{cue8e Surpun; e1e,,lrJd e'uorlepunoC prqrrg uerTe.l1snvaqlJo poFad errr€ssJql Ja^o osg oqJ elqJssoduoeq a^sr{ asrn roqlo plno,r upql qJJuaseJJlluurelsds pruro; ur 'selEg 'U 'seuof 'I'C'so^lastno ecue,rpeplder erour pue e,rqcnpordu o1pel seq pue slueuelC V I I qll,{Sulnulluoc pu?a8roeg g y qlr,rSuoueuuoc'dnoJC orll qll,rslsuuouoxel prqcroluuorsse;ord;o 'exel luelrrellolut asolC peqlrcsepun,{ueurgo uorlerryluapr pue uorleJol eql pelelllrJeJseq sprJlsrp JreqlJosPlqJJo eql q1y'rruqluu; dleluunlursrequreru,{-4unoc3o uorsradsrp 1n;asn v sraqdeJSoloqdpuu slsErsnqlueprqJro peIHsJoJequnu?ulseoJJul ue JoJ punorSSurqzrl e sepoqqrnog puupedoleaep srq dnorg uorle,r:esuo3pu€ i(pnlS prlclO e^llBNuell84snVulelsei[ aql'sepBrepo^! ls€der{t ro^o',{IsrC 'scperuelsds plqcro u:elsea-r{lnosut secuelpeluoJJnJ aql ol pelnquluoc e^pq slueuala,{a1om1 'pe^alqJeeq uer tuesordexet aqt;o Surpuelsrapun11n; u eroJoqEJoU prqcJo s,uorSar eql uo auop eq ol spoeuI[gs oJoruqcnhl srTtr1snv tuelsaA\-qlnosur slre,rerduorlenlrs:eJJuls E',,osJrfuns ou seouroc llr,nrededsrql ur sercads.reuperpunq 'oeetuplqsro euo uuql eJou Jo uolldF sePeql usrlEJlsnveql urqlr,trsdnor8 xeldruoc q1r,nrellltuu; puB qcJBesersrql qlr^\ pelercosseasoql ol,, 'eeoceplqcJou?lJpJlsnv ruelsee uo uoqnqrrluoc rofeur slq ol uolleleJuJ lEql polJeurel (I :1661) sauol se 1sn1 puEqol etllos sexeldruocserceds go sarpnls pelJ€lopJo sllnsoJeql sEJse( qceepaglluepr eq ol senurluocEx?l A\euJo qllua,r V epuu ueeqe^pq '€rTuJlsnV sprqcrotuelse^\-qlnosJo sorJe^orsrp luecer ,{ueur 1eq13ursrrfuns 1ou sdeqrad sr 1r ulolsoi( ur 'slsruuloq luoplseJsleuolssolord;o ,{lrcnudeq1 pue pler; ldepelsou aq1o1 se8ue1leqr esaql ue^rC 'tg'a u|olt8uo1 sttnr1 J!.J'J'a ouou sr1t1sota14 "qqcreg ''rg'dtruosnpd "Jg'\osouawoltl g g rca8anq D J otuapoloS [,qpegrddl esoqlse qcns saxeldurocsarceds roJ uolAeJaql lnoq8nor parolunoruesluuuu,r;o uroqlald eql uo seureuSurculd 'uxul pue Sutpuelsrapunul dleq onlllJo aJe.t deq; luurru,rur,{le,rgu1er aq1 uo fluo uopeurJoJqInJosn papr,lord(tr961 unaorg ? uBruJJoH:996I uo$lclrA :0€6I eolled) sprqcro ruolse^\-qlnoso1 sep1n8 '(9661 '7661) 'flel?unuoJun PIaIJolqullu^e eql u.,torg T, uutulJoHJo uoll€crlqndluece.r aq1 lpun 'lse.,'r-t1lnosrqt ur eraueBqrg -sarceds:aq1opua (186I ?r raroddoH) s{ KlsouoS'(966y'6961'2961eul..lLo1)otasolg'(1661aEroeg) '(9161 DtprocuoA ullsuyq)arraey'(1661 reddoll 4lo{oorg:0661 31u1a1a4 ra4oo-rg)sndqocnq 'srnJso uI ueesl3r{l 01elqBreduoc slu?rrel pelrler ,{Iaso1c;olueuacsldor [€r!8o1ocero pclqderSoeS prdeg fSoloqdrour IeJoUu uorlerJel Jo ,{ErrBSuuep1,req e fzldsrp sprqcro;o sdno:3 euog '(9661 p o uoxrqlts6l eled ? uoxlq) s?lrsu,trou>[ ulqll.,.r elecol ol srnoq-uosredeuru;o e8ure,ru uB e{€l seoueJseJogurueeuerJelqns alrsnle esoq,{ elrsendrde us 'sJeSoU'A uaupo? oya4luozyqy 'pqcrg punor8rapu1eql qlra tse^\-qlnosaql ut qlruezslr saqoeerSuuer','og cpd,{ro ,{lrsualsrpw erurl eleudorddeaq1 1e erlJ roge ldecxo[p ts Je.trog{le]EI sprrlcloeurog uor1e1e3ea.ppueJod JeAlpleql dq ?uuds u1paraj;ord rnolor Jo lorJ eql ur peloolra,lo ,{gseee.lr l€ql sJa.rog snoncrdsuocurlltrrrs al€q '6661 eleue8aruog ,(q satceds79 pup (966I u,rorg T, reddog) reluysrzed ua,ras sarceds 67 o1(9961 euueg) oAEepsrep e serJedsgZ ruo{'A\oJ8 ol sanqluoc lsll prqcrooql',{lp

Brown July 2003 Department of Conservation and Land Management Western Australian Threatened Species and Communities Unit PO Box 51, Wanneroo, WA 6946. Interim Recovery Plan for Caladenia drakeoides FOREWORD Interim Recovery Plans (IRPs) are developed within the framework laid down in Department of Conservation and Land Management (the Department) Policy Statements Nos. 44 and 50. IRPs outline the recovery actions that are required to urgently address those threatening processes most affecting the ongoing survival of threatened taxa or ecological communities, and begin the recovery process. The Department is committed to ensuring that Critically Endangered taxa are conserved through the preparation and implementation of Recovery Plans or Interim Recovery Plans and by ensuring that conservation action commences as soon as possible and always within one year of endorsement of that rank by the Minister. This Interim Recovery Plan, which replaces IRP 29 (Drakonorchis drakeoides ms) will operate from July 2003 to June 2008 but will remain in force until withdrawn or replaced. It is intended that, if the taxon is still ranked Critically Endangered, this IRP will be reviewed after five years and the need for a full Recovery Plan will be assessed. This IRP was approved by the Director of Nature Conservation on 21 July, 2003. The provision of funds identified in this Interim Recovery Plan is dependent on budgetary and other constraints affecting the Department, as well as the need to address other priorities.

Transnordestina s.n., 44036-900, Feira de Santana, Bahia, Brazil 3Fazenda Rio do Negro, Entre Rios, Bahia, Brazil Abstract The monospecific genus Discyphus, previously considered a member of Spiranthinae (Orchidoideae: Cranichideae), displays both vegetative and floral morphological peculiarities that are out of place in that subtribe. These include a single, sessile, cordate leaf that clasps the base of the inflorescence and lies flat on the substrate, petals that are long-decurrent on the column, labellum margins free from sides of the column and a column provided with two separate, cup-shaped stigmatic areas. Because of its morphological uniqueness, the phylogenetic relationships of Discyphus have been considered obscure. In this study, we analyse nucleotide sequences of plastid and nuclear DNA under maximum parsimony

  • Wa Orchid Spectacular 2017 Four Day Tour
    WA ORCHID SPECTACULAR 2017 FOUR DAY TOUR Tour 1: 7–10 August 2017 Tour 2: 8–11 August 2017 Notes for attendees The four day tour will comprise two identical trips staged one day apart. The first trip departs from Perth on Monday 7 August and will be led by Andrew Brown author of ‘Orchids of Western Australia’ and ‘Field Guide to the Orchids of Western Australia’. The second trip departs on Tuesday 8 August and will be led by Garry Brockman co-author of ‘Field Guide to the Orchids of Western Australia’. The daily itinerary is tentative and may be subject to change. If we hear of particularly good orchid populations that are not currently included it may be modified to incorporate them. Some currently listed locations may also be removed if it is found they do not contain good orchid populations this year. It is anticipated, however, that most locations listed here will be visited during the trip. We will do four planned orchid stops most days but, if time permits, will also do one or two additional opportunistic stops. The amount of time spent at each planned orchid stop will vary depending on the number of orchids seen but will usually be around 45 minutes. Opportunistic stops will generally be around 30 minutes. We will also have two comfort stops each day, some of these coinciding with orchid stops. Orchids listed for each site are the ones that we are most likely to see but are not guaranteed with species/numbers seen dependent on seasonal influences in 2017.

Due to the growth of the Society over the past twelve months, the quantity of plants received for sale on the trading table has in- creased dramatically. It has now reached the point where the number of plants brought in each month for sale has become unmanageable. Many of the plants are not sold and have to be returned to the owner sometimes in a damaged condition due to the rough handling received in the melee at the table.

  • Alternative Translation Initiation Codons for the Plastid Maturase Matk: Unraveling the Pseudogene Misconception in the Orchidaceae Michelle M
    Barthet et al. BMC Evolutionary Biology (2015) 15:210 DOI 10.1186/s12862-015-0491-1 RESEARCH ARTICLE Open Access Alternative translation initiation codons for the plastid maturase MatK: unraveling the pseudogene misconception in the Orchidaceae Michelle M. Barthet1,2* , Keenan Moukarzel3, Kayla N. Smith1, Jaimin Patel3 and Khidir W. Hilu3 Abstract Background: The plastid maturase MatK has been implicated as a possible model for the evolutionary “missing link” between prokaryotic and eukaryotic splicing machinery. This evolutionary implication has sparked investigations concerning the function of this unusual maturase. Intron targets of MatK activity suggest that this is an essential enzyme for plastid function. The matK gene, however, is described as a pseudogene in many photosynthetic orchid species due to presence of premature stop codons in translations, and its high rate of nucleotide and amino acid substitution. Results: Sequence analysis of the matK gene from orchids identified an out-of-frame alternative AUG initiation codon upstream from the consensus initiation codon used for translation in other angiosperms. We demonstrate translation from the alternative initiation codon generates a conserved MatK reading frame. We confirm that MatK protein is expressed and functions in sample orchids currently described as having a matK pseudogene using immunodetection and reverse-transcription methods. We demonstrate using phylogenetic analysis that this alternative initiation codon emerged de novo within the Orchidaceae, with several reversal events at the basal lineage and deep in orchid history. Conclusion: These findings suggest a novel evolutionary shift for expression of matK in the Orchidaceae and support the function of MatK as a group II intron maturase in the plastid genome of land plants including the orchids.

BACKHOUSE Biodiversity and Ecosystem Services Division, Department of Sustainability and Environment 8 Nicholson Street, East Melbourne, Victoria 3002 Australia [email protected] KEY WORDS:threatened orchids Australia conservation status Introduction Many orchid species are included in this list. This paper examines the listing process for threatened Australia has about 1700 species of orchids, com- orchids in Australia, compares regional and national prising about 1300 named species in about 190 gen- lists of threatened orchids, and provides recommen- era, plus at least 400 undescribed species (Jones dations for improving the process of listing regionally 2006, pers. comm.). About 1400 species (82%) are and nationally threatened orchids. geophytes, almost all deciduous, seasonal species, while 300 species (18%) are evergreen epiphytes Methods and/or lithophytes. At least 95% of this orchid flora is endemic to Australia.
