Every month, NOSSA holds a photograph competition. The entries were varied and beautiful but they were only being seen by the members at the meetings, so it was decided to showcase these lovely orchid images in a calendar.
The overall winner from 2018 would be on the front cover and we would select twelve from the fifty-one 2018 entries. The challenge was to select the twelve. This was done by having an on-line vote for the twelve most popular pictures. And I would like to thank all who entered and all who voted.
Having collated the votes to find out what was the most popular orchids, the next task was to design an informative calendar giving information about the South Australian orchids featured as well as significant NOSSA event dates and a very rough guide indicating when the orchids are likely to be flowering.
If you are interested in ordering a calendar, contact NOSSA as per the details on the flyer above.
Every year, NOSSA holds monthly photograph competitions. This year, NOSSA decided to give the entrants an opportunity for their photographs to appear on a calendar. There have been 51 entries this year, so we are asking people to vote for the twelve images that they would like to see in a calendar.

April’s theme was yellow and orange. All of the entries proved to be spring flowering. There were several Diuris. Claire Chesson, Rob Pauley and John Fennel all entered D. orientis; Les Nesbitt and Rob Pauley D. behrii and Pauline Meyer D. corymbosa from Western Australia. Pauline also entered Caladenia caesaria subsp. maritima and John Thelymitra benthamiana.
The winning picture was Les Nesbitt’s D. behrii (Cowslip Orchid) which occurs in Victoria, New South Wales, Australian Capital Territory whilst in South Australia it is rated as vulnerable.
Les Nesbitt has been working on a recovery project of these orchids for Hillgrove Resource’s flagship, the Kanmantoo Copper Mine, located almost 55 KM from Adelaide. As this orchid is often mentioned in NOSSA Journals, it might be worthwhile looking at the person after whom this species was named.
First collected by German born Dr Hans Herman Behr (1818 – 1904) who first visited* South Australia in 1844 when the colony was barely 8 years old. During his two years in South Australia he became the first person to systematically study our botany and entomology sending reports and samples back home. The results of his observations were published in various journals, and many of his collections were named and described by other botanists including his friend, Diedreich von Schlechtendal (1794 – 1866) who named Diuris behrii after Hans.
Hans Behr was an interesting man. A man of many aptitudes; medical doctor, entomologist, anthropologist, botanist, duellist, socialist, poet, novelist, linguist, member of the Bohemian Club of San Francisco and a man of wit. From the many reminiscences written about him, it would appear that he was a likeable gentleman and a generous teacher.
Unfortunately, not everyone liked him because “he was a sworn enemy of all scientific humbug, of quacks and false pretenders” and “he never refrained from expressing his opinion of them, quite regardless of person or station” but his humour shone forth in dealing with them. Once he named a “particularly obnoxious louse” after one of his enemies.
Behr revisited South Australia in 1848 during which time he became acquainted with German-Australian botanist, Ferdinand von Meuller. He maintained friendship with many of the scientific men of the time including Ferdinand Mueller and it was through this friendship that many Australian plants were introduced into California where Behr later settled after his travels.
Though the study of butterflies was his first and enduring love, he is remembered and honoured in Australia for his botanical interests. Of the twenty-two plants named after Behr, two are orchids: Diuris behrii and Arachnorchis behrii (synonym Caladenia behrii).
*The Journal incorrectly stated that he visited South Australia with his friend, Diedreich von Schlechtendal. This did not happen. As far as I am aware Schlechtendal did not visit South Australia.
As part of 40th NOSSA anniversary, the theme for this month was Leptoceras menziesii (Hare Orchid or Rabbit Ears). Entries were received from John Badger, Pauline Meyers, Robert and Rosalie Lawrence, with John Badger’s being declared the winner.
In February 1978, it was announced that the nascent NOSSA society required an emblem. Members were invited to send in drawings, to be judged by members and then ratified by the committee. Mrs Chris Butler (Ron Robjohns’ daughter) was the winner. The first Leptoceras menziesii flowers to be benched at a NOSSA meeting were in September 1978. It appears to be an easy plant to grow but a most difficult one to flower.
This seems to be because it is fire dependent. In spring, it will flower profusely if there has been a summer fire such as occurred after the 2015 Sampson Flat (SA) fires. It is possible that the gas ethylene produced during a fire event may initiate the flowering response.
Otherwise, apart from the occasional flowering plant, it will be mainly leaves that are found when out in the field. The single leaf of this plant lying prostrate along the ground is distinctive. It is firm, boat-shaped, glabrous (no hairs), with a fine ‘snake-skin’ pattern. Interestingly, sterile plants can be mistaken for a plant with a developing bud as there will be at the leaf base a ligule (a thin membranous growth, often found on grass stems).

Ten years ago, the then NOSSA secretary, Cathy Houston, wrote an article reflecting upon orchid name changes. Since then there have been more name changes. The issues she raised then are still pertinent today. Whilst we continue to learn more about our orchids, name changes are going to happen.
NOSSA Journal Volume 31 No 2 March 2007
HAVE OUR ORCHIDS CHANGED? Cathy Houston (Secretary)
This month the Native Orchid Society of South Australia celebrates its thirtieth “birthday”. A review of the first five years of the Society’s Newsletters/Journals (yes, they were newsletters in the earliest days) reveals some interesting points. By 1979 “A total of 110 species [of orchids] and 14 varieties” were accepted. The following are some interesting aspects about the knowledge of, and what was then current thinking about, our orchids at that time. It must be remembered that no comprehensive book on South Australian orchids existed in those days, especially not any field guides. The most useful “tools” the members had to work with were Blacks Flora of South Australia and W.H. Nicholls “Orchids of Australia”. In 1979 “A Checklist of Orchidaceae on South Australia” by J.Z. Weber: Changes introduced in the new ‘Black’s Flora” by R. Bates, appeared as a full issue of the Native Orchid Society of South Australia Journal.
Today we sometimes struggle to grasp all the fine differences when orchid species, or species groups, are split, but spare a thought for those wanting to identify with what they have seen in the field back in about 1979. An article by R. Bates describes the “Variations within the species Caladenia dilatata R.Br. in South Australia”. “There are, at present, two recognised varieties” viz. C. dilatata var. dilatata and C. dilatata var. concinna. Within these two varieties are further more divisions into distinct sub-varieties or races! At that time there were six distinct forms recognised; how much easier today, now that they are named as species. These would now include C. tentaculata, C. verrucosa, C. stricta, C. toxochila and C. conferta.
Recognition of what could be species has long been apparent. Take for example the article written in 1980 about two forms of Pterostylis nana, viz. what we commonly refer to as the ‘Hills’ form and the ‘Mallee’ form. This article documents the obvious morphological differences and illustrates this with line drawings and a map showing distributions of the two. Electronic Orchids of S.A. currently recognises five possible species of P. nana for South Australia. These are probably all un-named, since David Jones, in “Native Orchids of Australia”, does not recognise true P. nana in our state. Similarly, an article written in 1981 discusses the P. alata – scabra – robusta complex. The author recognises there are “at least four species of this group in South Australia”. This is the first time the authors acknowledge they should be elevated to species, not just accepted as varieties or forms. At that time P. robusta was treated at varietal level, viz. P. scabra var. robusta or P. alata var. robusta. Ultimately most of these have been elevated to species level (P. dolichochila, P. erythroconcha, P. robusta, and P. striata).
It was noted that in 1978 David Jones and Ray Nash were currently working on Pterostylis. Further to that Les Nesbitt notes that of the sixty or so Pterostylis in Australia, South Australia has twenty-two species. One wonders what the count is now. It is well known that David Jones is currently/still working on the Pterostylis group, with more species being recognised regularly.
In a series of articles produced about “Our rarest orchids” in 1977 we find the comment “Very few of our orchids are thought to be extinct… . “One wonders what that number would be considered to be today. The same article talks about the demise of Pterostylis cucullata and the possibility that it may no longer exist in the wild. Certainly this is one of our highly endangered species for which recovery actions are being undertaken these days. [N.O.S.S.A. members have an opportunity to assist with this work starting on April 14th – see diary dates.] In 1977 there was excitement when, following a field trip to Belair National Park one member returned the following day and “the elusive Pterostylis cucullata” was seen “growing in association with P. curta”. In 1981, following a discussion and review of endangered orchids in South Australia, R. Bates writes “There are a number of endangered species in S.A. which have not yet been named. It is not unlikely that some of these will become extinct before they are even described properly.” With such a large number of as yet undescribed orchids in our state, let us hope this does not happen.
Naturally occurring hybrids and the naming of such, has been debated regularly within botanical circles. In 1978 this insight is shown by Ray Nash who “guided us to a nearby patch of Thelymitramacmillanii,…… Ray’s view is that this will probably turn out to be a hybrid, possibly between antennifera (which it closely resembles) and rubra or luteocilium.” In 1980 T. decora [T. x truncata] was featured as one of South Australia’s rarest orchids. It was thought to be of hybrid origin and three forms were recognised then. The probable parents were T. ixioides x T. longifolia, T. ixioides x T. pauciflora, and T. ixioides x T. mucida. Today with the naming of many species within the T. pauciflora complex, it is now being recognised that there are even more combinations producing similar type flowers, e.g. T. juncifolia, which gives rise to the spotted features, x T. brevifolia.
Name changes always raise controversy. A brief explanation giving some insight into this complex area can be picked up when an author is expanding on the front cover illustration of Corybas. “In fact, they should never have been called Corybas in the first place. They were discovered by Robert Brown during the Flinders Expedition (1801 – 1805), and illustrated by the Austrian Ferdinand Bauer, another of the members of the expedition. Brown called them Corysanthes from the Greek “korys” (a helmet) and “anthos” (a flower), and they were known for many years by that name. However, in this instance, justice was never truly done, because the decision was made to call them Corybas, the name previously allotted by R.A. Salisbury in 1805, on the strength of seeing Bauer’s illustrations.” More recent times have seen that injustice righted with the name reverting to Corysanthes, something brought about through the work of David Jones. Similarly, the latest naming of Corunastylis tepperi follows this, The International Code of Botanical Nomenclature, a name that was recognised by R. Bates in an article written in 1981! However, Bates concludes that P. tepperi and P. nigricans are synonymous, so the latter prevails, but “further work needs to be done”! He is also the author of an article depicting some name changes in 1980. If our readers are confused by “new” names, then just think what it was like for those in 1980 when, among others, Caladenia carnea, and all its five varieties, is changed to C. catenata, with all its varieties, two of which are C.catenata var. gigantea and C. catenata var. minor. Two others were elevated to C. pusilla and C. alba.
At one time our esteemed orchidologist was asked to comment on a list of name changes being proposed for the revision of Black’s Flora of S.A. “My first reaction was to state that everyone would be happiest if no changes were made”! However, in fairness to that gentleman, it must be said that by the time he had worked through a lengthy consultation with botanists covering much of Australasia, a revision of type specimens and other material and associated literature, he was clearly of the opinion that the changes were warranted.
Have our orchids changed? Maybe, but what has really changed is our knowledge and understanding of these unique plants. Based on that knowledge, opinions, attitudes and ideas have changed. Thirty years ago it was not “policy to differentiate between the numerous forms of C. patersonii in this State …” Today we have numerous named species in this complex, without actually any Caladenia patersonii as such.
The final word must come from Peter Hornsby when he said “The ultimate aim should be for the reader to know which plant is being discussed, rather than whether or not the title is absolutely correct.”

South Australia has some beautiful and delicate orchids. Most are not showy. Instead they have a subtle attractive beauty. But they are declining; and for that reason, they are protected by the law, specifically the Native Vegetation Act 1991. Picking the flower is illegal let alone digging up the whole plant.
The only situation where a person can legally remove an orchid or part thereof is when they hold a government authorised permit. Legitimate reasons for collecting orchid material include specimen for the State Herbarium, scientific research, rescue or salvage situations when a development is occurring, or collecting seed of threatened species to store with the Seed Conservation Centre.
Without a permit, no one can remove any part of a plant even if their reason is legitimate.
It behoves members to be cautious of any one that asks for assistance with collecting, transporting or photographing potted orchids. Ask to see their permit. So, what do you do if you suspect someone of picking the flowers or digging up the plants? Contact the Department Environment and Natural Resources Investigation and Compliance Unit.
There is only a very small number of NOSSA members who hold such permits. Thelma Bridle, NOSSA Conservation Officer, is the person who will know which members hold a permit. For more information on plant collection permits, contact DEWNR at DEWNRresearchpermits@sa.gov.au or visit the website.
Thank you to Thelma Bridle and Doug Bickerton for their assistance and critiquing of this post.
Spring is here and it was reflected in the variety and large number of entries. Lorraine Badger and Ros Miller entered Western Australian species – Caladenia x ericksoniae (Prisoner Orchid) and Paracaelana nigrita (Flying Duck Orchid) respectively. The other six entries were all from South Australia, Diplodium robustum (Common Green Shell Orchid), Caleana major (Flying Duck Orchid) both from Jane Higgs, Greg Sara’s Oligochaetochilus sp (Rufoushood), Judy Sara’s Arachnorchis leptochila (Queen Spider Orchid), Claire Chesson’s Diuris behrii (Cowslip Orchid or Golden Moths) and the outstanding winning picture Pterostylis cucullata by Bevin Scholz.
In many ways, Bevin’s picture of P. cucullata (Leafy Greenhood) is a special picture because it represents some of the conservation work with which NOSSA is involved. For many years NOSSA has worked with the Threatened Plant Action Group (TPAG) to weed the areas in Belair where this species is located and to see such a good show of plants is encouraging. It is a tribute to all who have contributed with their time and labour.
P. cucullata is rated Vulnerable both in South Australia and Victoria, and Endangered in Tasmania. It is also rated Vulnerable under the EPBC Act (Federal). Nationally it is known from about 110 sites with most of these sites being in Victoria and only a few sites in South Australia with Belair National Park having the largest and most important population for the state.
Historically this species covered an area of 2107 km2 in the Lofty Block region but that has now contracted by 82% to only 366 km2 with few locations. With such a reduced range, recovery plans were developed, both at state and federal level. The plans examined the risks and threats to the survival of the different populations.
One of the threats to this orchid is fire, including proscribed burns. Unlike some species such as Pyrorchis nigricans, Leptoceras menziesii or Prasophyllum elatum which flower well after fire, P. cucullata is fire sensitive; populations decline substantially. There does not seem to be a safe time to burn for this species. Should a population survive a burn, it would take it many years to recover.
Fire also leaves the population vulnerable to another threat, that of weed invasion. Unfortunately, it is weedy where this species survives but over the years, a consistent, targeted weeding program has resulted in a declining weed population. NOSSA and TPAG have appreciated the work and effort of volunteers and gladly welcome anyone else who would like to join. And one of the rewards? A beautiful, sunlit display of flowers as seen in Bevin’s picture.
The Native Orchid Society of South Australia (NOSSA) is affiliated with the national body of native orchid society, Australian Native Orchid Society (ANOS). NOSSA regularly sends reports of its to ANOS. This year’s report covered four years of the society’s activities and is reproduced here to give readers an idea of the many things that we do. This report was produced by Robert Lawrence (currently Vice President).
NOSSA REPORT 2012 to 2016
I believe that the last annual report from the Native Orchid Society of South Australia was in 2011 when we were just commencing a three-year plan with the establishment of a series of subcommittees. All of the committees have since ceased to exist, but not without significant accomplishments.
The Website Subcommittee had established a website, but a Webmaster has since been appointed. The website now uses WordPress and is maintained so that its management could easily be transferred to another person. The website provides a weekly educational post about Australian orchids. It has also provided a point of contact from those outside of the Society. It is linked to a Facebook page that increases the profile of NOSSA among those interested in orchids throughout Australia and beyond.
The Education Subcommittee had established a picture competition at the monthly general meetings. There is still only a small number of contributors, but many excellent pictures are shared. The winning picture from each meeting is used as a basis of one of the weekly posts on the website.
The Education Subcommittee had a vision to produce a brochure of 20 common orchids of the Adelaide region for free distribution to the general public. The NRM (Natural Resources Management) Education ran with the idea and produced a poster of Common native orchids of the Adelaide Hills. This provided brief, but comprehensive, profiles of 29 native orchids and the weedy species. This has been printed as a double-sided poster and is available from the website of Natural Resources Adelaide and Mt Lofty Ranges. NOSSA members worked with NRM staff on the details of the poster and NOSSA members contributed many of the photographs. This poster was completed and launched in April 2015.
NOSSA also provided monetary assistance as a loan with the publication of the field guide entitled, Start with the leaves. A field guide to common orchids and lilies of the Adelaide Hills. This guide covered 50 orchid species as well as native lilies and some weeds in the Iridaceae family that are sometimes mistaken as orchids. The contribution of $8,000 was recovered only 8 months after publication.
The Disc Publication Sub-editing Subcommittee saw the publication of South Australia’s Native Orchids on DVD discs in time for the Spring Show in September 2011. Both the DVD and the book were published in time for the Spring Show in September 2011. Both continue to sell.
A new subcommittee has been established in February 2016 to oversee the publication of a field guide, expected to be called Wild Orchids of South Australia. It is proving to be a challenge to be brief enough to reduce the information to a size suitable for a field guide. (Editor’s note: it has since been decided to defer this until after the development of the interactive website, see below.)
NOSSA members have being working since 2014 to establish an interactive website and database modelled on the Go Botany website run by the New England Wild Flower Society in the USA. This was supported by a grant from the Australian Orchid Foundation. The project is called Wild Orchid Watch. It is hoped to produce an interactive, web-based orchid identification tool. Recording sightings through such means as apps on mobile telephones are also being investigated.
In 2014 NOSSA made a donation to help establish the Orchid Conservation Program. This was led by Dr Noushka Reiter. Once established, staff in the Department for Environment, Water and Natural Resources began to organise a trial with four threatened orchid species from South Australia. Noushka visited South Australia during 2015 and collected samples from each of these species and isolated fungi from these. Seed was also collected and work on propagation commenced in 2015. During 2016 NOSSA sponsored the propagation of one of the four species through the Adelaide Botanic Gardens. Caladenia gladiolata, an endemic species, was selected.
Paul Beltrame, a secondary teacher at Kildare College, contacted and joined NOSSA during 2014 with the interest in getting girls at this school involved in the propagation of native orchids. A program was organised modelled in the Orchids in Schools program run by the Orchid Club of South Australia with Les Nesbitt’s involvement.
A delegation from Kildare College, ably assisted by their enthusiastic laboratory assistant Nenah McKenzie, visited Noushka in Melbourne and learnt the technique for separating and growing fungi. They have since separated fungi from two of our more common greenhood species and supplied this for seed kits that were made available to members as a trial at the start of the 2016 growing season.
The trial of seed kits was done for Pterostylis nana and Pterostylis sanguinea. A trial was conducted in this growing season of seed kits for members. Kits included a pot, growing media, seed, fungus, mulch and instructions. There seems to be limited success with the current round, but improvements are planned from the lessons learnt. One particular growing mix proved successful with a small number of seedlings appearing. The contribution of the Orchids in Schools program at Kildare College has been necessary for the isolation and production of fungi for the kits.
In October 2012 Cathy Houston and Robert Lawrence collected seed of Pterostylis arenicola from the only population on the Adelaide plains after monitoring in September indicated a good year for seed production. The seed was germinated in 2013 and was deflasked at a working bee at the Adelaide Botanic Gardens in early August 2016. The students from the Orchids in Schools program at Kildare College participated. Latest reports are that 40 plants look like surviving. These will be used for seed production and for reintroduction.
In 2012 NOSSA was asked to care for and propagate rescued Diuris behrii plants from Hillgrove Resources Mining Lease near Kanmantoo in the Mt. Lofty Ranges. The plan was to maintain the rescued orchid clones in cultivation for several years and to produce additional plants for reintroduction within the mining lease area each Autumn. A comprehensive recording and auditing system has been put in place to track each clone and any seed/daughter tubers/plants. By August 2015 there were 609 plants with 75 original mother plants. There were 95 daughter plants returned to the site for revegetation in each of the years 2014, 2015 and 2016, a total of 285 plants.
Funding from Hillgrove Resources has assisted NOSSA financially and has made it possible to consider funding conservation work. NOSSA is planning to apply for charity status so that donations can be used for tax deductions. Donations will then be feasible through our website. We are also starting an orchid seed bank. Seed will be available only to members and it is hoped that this will increase our membership. There is a demand for Australian orchids overseas and it is hoped that this will become a means for raising funds for conservation. Other means of fund-raising such as sausage sizzles and selling kits for craftwork are also being considered.
NOSSA members still continue to be involved in surveys and monitoring threatened orchids. Members have been involved in the planning of monitoring.
The management committee of NOSSA is currently working on a revision to the Rules of Association. In the current version there is a two-year limit on the term of the President of two years. In the first 16 years from 1977 there were there were eight different presidents before one had a second term. Bill Dear was president in alternate terms until he retired and moved to Western Australia in 2012. Robert Lawrence was elected president in March 2014, but for the first time in 2016 there were no nominations for president and he was nominated to the role of vice president with no other nominations. The management committee has appointed a subcommittee to review the Rules in relation to the terms of the president. Another change planned is change from having monthly general meetings to having less formal monthly meetings at which no decisions are made or minutes kept. All resolutions will require calling a formal special meeting. This idea is adapted from the approach used by ANOS Victoria.
Over the last two years NOSSA has asked new and renewing members to complete a survey of their interests. This has proved to be an effective way of getting information on the interests of our members with 79 responses, this being about half of the number of memberships. This is an overall summary of the results ranked according to number of responses:
Area of interest
General Orchid Knowledge
At its establishment NOSSA was primarily a Society of orchid growers. These figures reflect a decline in interest in growing orchids. The figures are somewhat surprising in that the numbers interested in growing orchids are much larger than the number of growers. Presumably some of these are interested in learning with a view to getting involved with growing later. At least we hope this is the case.
We are certainly noticing a decline both in our numbers of growers and in members involved in surveys due to age and health.
The greatest number expressed an interest in general knowledge and we are relying on the Journal and the Website help to keep people interested and informed. Next was field trips, but we haven’t had that many that have attended field trips in in the last few years. Only 11 of those who expressed an interested in field trips are not interested in photography, the next item of interest, and only 10 people interested in photography were not interested in field trips. Not many of these share their photographs at monthly meetings. We are hoping to get members to make their photographs available for the identification guides.
It is pleasing that 58% are interested in conservation, thus supporting the efforts of our Conservation Officer.
Growing terrestrial orchids was next on the list; we hope that the tuber bank and the NOSSA Seed Kits are meeting the demand from members. Twenty-two of the 41 interested in growing orchids are interested in growing both terrestrial and epiphytic orchids. Only 8 of the respondents are bringing plants to meetings and a couple of others have not completed the survey. Of those interested in growing terrestrial orchids, one is a former grower and another is interested in growing them in situ at revegetation sites.
Thirty members expressed an interest in doing orchid surveys and three of these are interested in participating in the future, presumably when more time is available.
Citizen science is a new concept to many and came last in our list of interests. One who did not indicate an interest said he was monitoring orchids at a particular site; this has been taken as an interest. Surveys are certainly one form of citizen science and only 2 of those who indicated an interest in citizen science did not indicate an interest in being involved in surveys now or in the future. Thirteen of the 30 interested in surveys did not express an interest in citizen science. If these were included, interest in citizen science would be 43%.
Only seven members indicated an interest in all of the categories and one of these wants to keep in touch with the club and with old friends.
The Annual Spring Show in September 2015 was a particular success, largely due to the efforts of one our new members in promoting the show through local media and by other means. We also benefited from the donation of collections of growers who had decided not to continue with their collections.
NOSSA has continued to maintain a tuber bank that is available for members. A small number of our members are also members of ANOS Victoria, and have obtained tubers from their collection. This is hopefully contributing to the variety of terrestrial orchids grown by our members.
Working bees continued to be conducted in association with the Threatened Plant Action Group at Belair National Park for improving habitat for the nationally endangered Pterostylis cucullata (Leafy Greenhood), at Grange Golf Club to protect and monitor Pterostylis arenicola (Sandhill Greenhood) this being nationally vulnerable and locally endangered and on York Peninsula in conjunction with a local Friends group for the nationally endangered Caladenia intuta.
NOSSA has for many years used Australian Orchid Club (AOC) judges and knowledgeable members, who have all studied the ANOS judging rules, to judge orchids at NOSSA monthly meetings and shows. As the number of judges has fallen in recent years, judging training sessions have had to been discontinued. We wait in anticipation for a proposed ANOS judges correspondence course, as we have for more than 10 years. There are at least three AOC judges interested in the ANOS judging correspondence course. It is disappointing that ANOS Awards are still limited to Queensland, New South Wates and Victoria.
In summary, NOSSA continues to be active in many ways and these activities are working together to support each other.
Internationally, there is concern about the decline of orchids as seen in the resolutions passed in May 2016 at the International Orchid Conservation Congress Conference. In Australia, there are many orchid conservation projects in progress both in situ and ex situ.
The following are some examples of the varied work being done around the country by volunteers, orchid enthusiasts, ecologists, conservationists, academics and government departments.
From Victoria, work headed by Dr Noushka Reiter of the Royal Botanic Gardens Victoria has seen the propagation of threatened orchids from seed returned to their habitats.
And here in South Australia there are also various projects. Dr Noushka Reiter is also working with the South Australian Seedbank to help propagate four of our very threatened orchids. Members of the Native Orchid Society are assisting as also are Paul Beltrame (teacher) and students from Kildare College through the Orchid in Schools Project.
