From the President
Robert Lawrence
Presidential term as per NOSSA Constitution
There was no response from the membership about the term of the president mentioned in the previous Journal or to the request at the general meeting. At the committee meeting Les Nesbitt pointed out that the reason for a maximum term at the start was to allow different members the opportunity to hold office. There were five different presidents before one took the role the second time. It is now harder to fill the position, as it is for the secretary, treasurer and the editor. The contributions of all involved are greatly appreciated.
Orchid Collection Sale
A private grower, not affiliated with any orchid society, has made the majority of his collection available to NOSSA for a nominal amount. Some of this collection was made available at the last general meeting and more than half were sold. Most of these are being sold at bargain prices, simply because we don’t have room to keep them. More are to be sold at the next general meeting and as many of the remainder as possible at the Spring Show. A small number of choice specimens have been selected for auction at the September general meeting, after the Spring Show.
Spring Show
Please remember that the NOSSA Spring Show is approaching on the weekend of 19 and 20 September. We are still seeking the services of a Show Marshall to coordinate this event. Please contact one of the committee members if you have some knowledge of growing orchids and you think you can help.
Bio Blitz at Morialta Conservation Park
As part of the centenary celebrations of Morialta Conservation Park, a Bio Blitz will be held on 18 and 19 September. NOSSA will be conducting orchid searches during this event. As this clashes with the NOSSA Spring Show we will be looking for helpers. Please let me know if you are available to help assist. Further information can be found at: http://www.discoverycircle.org.au/projects/bioblitzes/
Orchids and prescribed burns
Several NOSSA members attended a workshop on the impacts of prescribed burning on orchids and their pollinators. As three of us had just surveyed a May burn site at Scott Creek these considerations were fresh on our minds.
Kirstin Abley from DEWNR (Dept of Environment, Water and Natural Resources) spoke about burning strategies, including the aim of controlled burns within reserves so that unplanned fires could be prevented from wiping out the whole of a park at any one time. Dr Renate Faast spoke about her research on the response of orchids to prescribed burns and Anita Marquart spoke about the effect of prescribed burns on pollinators. Finally Associate Professor, Jose Facelli, led a workshop session of small groups which discussed possible relevant research questions. We were asked to consider projects that could be done within a period of around three years to match the time for a doctoral project or research grant. Many interesting lines of research were suggested. However, the reported results of the research completed by Renate and Anita showed large variations that occur on a short timeframe.
I see a need for long term studies through citizen science projects to collect data that can be available to researchers. Afterwards Jose and I discussed the possibility of developing protocols for longer term studies of distribution of orchid species and of phenology (The scientific study of periodic biological phenomena, such as flowering, … in relation to climatic conditions).
Vale Judith Penney
Sadly Judy passed away peacefully on July 22, 2015 aged 67 years. As reported in our June journal, Judy was a valued member of NOSSA who was always willing to help. Her great love of orchids was demonstrated in her membership of various orchid clubs around Adelaide.

NOSSA Field Trip – Morialta Falls CP
Judy Sara
The forecast for cold conditions had not put people off visiting Morialta Falls on Saturday 18th July. There was a steady stream of people walking along the track and the parking spaces along the way were full. Luckily many of the cars destined for the NOSSA field trip managed to get a park together in the final car park. Jenny and Rob Pauley’s list of people who had booked for the trip and phone calls from those running late ensured that we waited for everyone and the 11 of us set off together.
The Morialta area is very familiar to Robert and Rosalie Lawrence who led this walk. The orchid information stored in their GPS started us off and much more data was added along the way. I am very much a novice orchid spotter so it was great to watch the experts and learn from them. Everyone willingly shared tips on what to look for and information about each of the species we came across.
The path was initially surrounded by sour sobs that may have crowded out the orchids. The first massing of orchids looked like gum nuts that had fallen into the grass. These fascinating Corysanthes diemenica (Veined Helmet orchids) were abundant as both flowers and leaves. The stalks were so short that the flowers seemed to be on the ground. In one patch we tried to look under the flower hoods to see inside only to find we were looking at olives that had fallen from a tree!
I began to understand the importance of ‘start with the leaves’ as the experts began identifying nonflowering orchids from their leaves. The rosette of narrow reddish tinged leaves of Disa bracteata (South African weed orchid) was spotted. A number of groups of orchids were identified by leaf type but there was not enough other information to make identification to the species level. These included Microtis (onion orchids) and Thelymitra (sun
orchids). A spring visit will enable identification of these when the flowers have opened. I think it will take me quite a while before I can distinguish the difference between grass leaves and the sun orchid leaves! Large wide flat leaves with parallel white lines that indicated Caladenia latifolia (Pink Fairies) were easier to pick and the hairy leaves of Glossodia major (Purple Cockatoo) were tentatively identified.
Leaves of the emblem of NOSSA, Leptoceras menziesii (Hare Orchid), were also found. A number of orchids were in bud but the flowers had not opened yet. These included Arachnorchis tentaculata (King Spider Orchid), Cyrtostylis reniformis (Small Gnat Orchid) and Pterostylis nutans (Nodding Greenhood).
The heart shaped leaves of Acianthus pusillus (Mosquito orchids) were lifted to show us the maroon colouring underneath. These plants were in flower and some had formed capsules. One plant of Urochilus sanguineus (Blood Greenhood) was also seen to have formed a capsule and many others were in flower.
There were many sterile rosettes as well. Seeing the greenhoods started a discussion of the July 3rd
NOSSA blog on moving labellums. Paul Beltrame has shown the sequence to his students.
Large colonies of Diplodium robustum (Large Shell Orchid) and Diplodium sp. Adelaide Hills, as well as hybrids of these two species, were seen. Diplodium robustum colonies consisted of sterile rosettes and plants in flower as did Diplodium sp. Adelaide Hills, which also had some spent flowers. The Hills nana (Linguella sp. Hills nana) was identified by its crystalline white flower stem hairs and plants were at various stages; leaves, buds and flowers.

Movement up the northern side of the valley was leisurely with everyone engrossed in identifying the orchids or capturing images of the plants. Those with thick jackets were glad of the warmth and others took laps backwards and forward to keep warm. The sun was shining on the south side but as it was lunch time that side was walked at a much faster pace.
It was a very successful trip with a total of 15 species identified and two other groups picked from their leaves. The flowers of seven species were seen: Acianthus pusillus, Corysanthes diemenica, Diplodium robustum, Diplodium sp. Adelaide Hills, Linguella sp. Hills nana Pterostylis nutans and Urochilus sanguineus.
Editor’s comment: Thanks Judy for your very interesting presentation of this field trip. It is great to have newer members writing of their experiences.
July Meeting Review Lorraine Badger
Despite the cold and frosty night it was wonderful to see almost 50 brave souls venture out. There was a buzz in the air as folk gathered around the trading table with its vast array of orchids and also around the benched orchid table.
Our guest speaker for the night, was Dr. Remko Leijs (In lieu of his wife Katja Hogendoorn who had another appointment.) Remko also has an academic background in native bees. His fascinating discussion on the topic, combined with amazing photographs and tales of his experiences, captivated the audience.
Whilst it is commonly known that honeybees, introduced into Australia c.1820, are good pollinators of our crops, the pollination services of our 3,000 native bee species in Australia, for both flora and fauna, in our horticultural systems and beyond is generally underrated or simply unknown. There is so much more
which one could share on this interesting topic but space does not permit. Remko has offered the
following links. ** See also free workshop on bees listed below.

After our fascinating last meeting I thought members
might be interested in this workshop by Remko Leijs. Renate Faaste
Native bee hotels – August 18th, 7pm at the Joinery, 111 Franklin Street, Adelaide
At this workshop you will learn about some of these fascinating locals, like the beautiful blue-banded bee. We will help you to make a “bee hotel”, a place
for native bees to nest in your garden. You can be like a fly-on-the-wall in your bee hotel, watching for thieving resin bees and industrious leaf-cutters. We’ll provide a way for you to share photos of what visits your hotel.

Scott Creek CP Orchid Survey Cool Season Burn 2015
2 August 2015
Robert Bates
In recent years many studies of deliberate late Autumn/Winter cool season burns have revealed that they cause serious damage to native orchid populations. Much has been talked about but little published: hence the need for a serious study. A prescribed cool burn was carried out along the Quarry Track in Scott Creek Conservation Park in May this year. 2015 has been a difficult year for orchids as it followed a serious rainfall deficit through late winter, spring and early summer of 2014 which caused replacement tubers to be only half their usual size. June 2015 saw less than half the normal rainfall in much of our orchid districts. July was not as dry but still showed a rainfall deficit and it was the coldest July for nearly 20 years, with severe hail storms in mid July causing terrible damage to orchids.
The survey was carried out on the orchids of two small areas of less than one hectare along the east side of Quarry Track, namely the burned area near the gate on Frith Road and the adjacent unburned section at the top of Almanda Track. Past visits had shown that orchid populations were similar in both with considerable overlap in species recorded.
Results: on Aug 1st 2015 four hardy NOSSA members began the study in scrubby, unburned ground at the top of Almanda Track which was a much smaller area than that burned.
We were surprised at the diversity of orchids present in flower and bud. Six segregate genera of green-hoods were present, mostly in good numbers. Pterostylis itself was represented by P. nutans with almost 100 in flower, Some near the gate on Frith Road were 25 cm tall and accompanied by rosettes of P. pedunculata.
Bunochilus was represented by B. viriosus with about 30 in flower and many seedlings. All had shorter scapes and smaller flowers than usual reflecting the harsh conditions discussed in the introduction.
Diplodium was represented by just a handful of D. robustum rosettes and many more further down the track, also with few poor flowers.
Linguella was represented by just one of the Park’s little greenhoods L. aff nana Hills of which there were hundreds many in flower but generally smaller than usual.
Plumatichilos sp unnamed were abundant with about 200 rosettes and a few with buds which were hail damaged. (The largest count ever recorded here.)
The 6th greenhood genus present in both flower and seed was Urochilus ( ie U. sanguineus) with about a hundred seen although mostly just rosettes. Other green-hood genera do occur in Scott Creek but were not seen on this survey.
In contrast, almost no greenhoods were seen on the burned area. A single Urochilus rosette was found unburned meaning it was a lucky tardy individual. A few Linguella were seen in flower on small unburned sections of the overall burn but any on burned ground had been destroyed.
Other orchids on the unburned section included Acianthus and Nemacianthus. The latter in hundreds with many in late bud and looking healthy. None had survived on the burned ground although a couple were seen on a metre square hardly singed patch.
Corysanthes were rare on the unburned patch since it is so exposed. They were tiny plants due to small tubers following the last dry spring. None had emerged on the burn.
Arachnorchis tentaculata were common on the unburned ground (at least 50) some with tiny buds although all plants were smaller than usual. None were seen on the burned area although a few leaves of A. leptochila were located on slightly singed ground and one with a tiny bud.
Cyrtostylis reniformis were sparse on both the burned and unburned patch. The leaves of this species often emerge in June and hence had avoided the fire.
Diuris: Both Diuris orientis and D. pardina were present in small numbers on the unburned section. The former with buds on tall scapes, the latter as leaves only. None were found on the burn and as the
Native Orchid Society of South Australia Inc. Journal Aug 2015 Vol. 39 No. 7
80
leaves of this genus emerge in May they must have been burned.
Glossodia: These were common on unburned ground (about eighty including some in bud.). Just one slightly burned leaf was seen where fire had
scorched the ground.
Thelymitra: The most obvious species was T. grandiflora with many of those on unburned ground showing strong buds (about 60 plants were thought to occur in the area). At least ten plants had emerged on the burned area, clearly
before the fire, as they all had the top few cm of the leaf burnt off. This shock
had caused any buds to abort and despite the huge tubers of the species the leaves were struggling. Since this species is stimulated to flower as a result of summer fire, the evidence was clear that damage is caused by cool season burns. Whilst there are many other species of sun orchid in the area we could not be sure of the species other than the obvious T. bracteata and brevifolia. Few leaves were on the burn and it appeared that none would flower.
Other species previously seen as leaves on the burn include a single cluster of Pyrorchis (2003) and one or two Prasophyllum leaves which had never flowered as they require a summer burn. How ironic that as leaves of these emerge in early May they must have been destroyed by the fire.
Summary: prescribed burns in the May to August period reduce the population of orchids by about 90% as shown by this survey where the number of orchid plants on the larger burned area was just 10% of the number counted on the unburned area and almost none would flower. Hence such burns cause serious environmental damage.
Conclusions: It is likely that 90% of the orchids on the burned area will never recover. Without a leaf, development of a viable replacement tuber is rarely successful. Over time species like Cyrtostylis reniformis, T. grandiflora and the half burned Glossodia should recover but other than Linguella and Urochilus, greenhoods are unlikely to return and the fire stimulated Pyrorchis and Prasophyllum seem to have been wiped out.
Shrubs and tree seedlings were abundant. Lilies like Burchardia, Chamaescilla and Thysanotus have emerged en masse after the burn, while yacca (Xanthorrhoea semiplana) have regenerated enough to suggest that in a couple of years the area will become quite dense and probably more of a fire threat than before. Any value from the burn will be minimal while many rare species are likely to have been wiped out. Follow-up studies will be carried out in October and again in 2016 . However, we would have to recommend that late Autumn and Winter prescribed burns are never carried out in this park or elsewhere in the Mount Lofty Ranges again as they are logistically and environmentally wrong.
Many thanks to Ed, Leo, Michael and Robert for their help during this survey.
Letter to the Editor:
… Perhaps your unknown plant, P67, Vol 39 No 6 July 2015, is Hybanthus floribundus - Shrub Violet. We have had quite a few flowering at Neagles Rock recently and although the image is not really clear I think that is a possibility. Regards, Pam O'Malley
Editor: Thanks very much for this Pam. Checking a googled photo against my original would seem to confirm this. Being a woody herb or shrub to 1.5 m high, it is so easy to overlook the beautiful, tiny flowers.

July Winning Photo
Rosalie Lawrence
Anzybas unguiculatas (Little Pelican or Cherry Helmet Orchid was the main focus for this month’s compe-
tition with 3 photos of this diminutive flower. The other photo-graphs were Ed Lowrey’s closeup of a triggered Urochilus sanguineus labellum, John Badger’s first Diurus palustris sighting this year and Pauline Meyer’s mass flowering of Leptoceras menziesii post fire. Of the Anzybas, Jenny Pauley entered two and Lorraine Badger one. Jenny Pauley’s photograph of two flowers was the outstanding winner.
Originally named Corysanthes unguiculata (1810), then Corybas unguiculatus (1871), the genus name was changed in 2002 to Anzybas in recognition of its distribution both in Australia in New Zealand. Since 1945 it had been recognised that the New Zealand species Corybas cheesemanii was a synonym for Corybas unguiculatas although the juvenile plant can have two leaves unlike the Australian species which is single leafed.
An interesting feature of this flower is the prominent white ears at the rear of the helmet (not clearly seen in this photograph) which are part of the labellum.
An unusual aspect of this photo is the colour of the underside of one of the leaves. It lacks the distin-guishing purple on the underside of the leaves. According to orchid growers, the light affects the leaf colour. Heavy shade produces green leaves. It is
possible that the heavy leaf litter where this plant was growing provided enough deep shade to cause the colour loss.
Bates (1990) states that it (has) not proved amenable to cultivation, but it has, on rare occasions, been benched at NOSSA meetings with the most recent occurrence in July 2010. However it remains very difficult to cultivate.
It is not always easy to photograph this tiny species since it is rare, has limited numbers and sites in S.A. Further, the window of opportunity is short in S.A. with a flowering time from June to August compared to those interstate which can range from May to October.
