Diuris calcicola (R.J. Bates)

This new species was named in the October issue of the Orchid Review 2015 and reported in NOSSA’s December journal. “It is a mallee species, growing across the limestone plains and rises from Victorian border as far as western Eyre Peninsula, often locally common. This bright yellow donkey orchid was previously included under D. pardina, a species restricted to the mountains from near Jamestown south to the Adelaide Hills. It was previously included under Diuris sp. Short Tails (NOSSA Journal Vol 39:11 p 128)

Events

On 18 June, Rosalie and I attended the BioBlitz at Lockleys. This was a trial one-day event, which made it easier for all. We walked around with a leaf-tailed gecko for much of the day, which helped to start conversations. We were able to tell quite a few people about our orchids.

The following week Rosalie and I participated in the Sturt Upper Reaches Landcare Group event on fungi and their restoration. Sapphire McMullan-Fisher, Fungimap Coordinator, presented a series of excellent talks on the Friday evening. She had an interesting perspective, saying that, unlike other organisms, fungi do their digestion on the outside. They emit chemicals that produce nutrients that they then take in. This is a leaky system and there is plenty of nutrient material that is not taken up by the fungi, but is available for plants. Of course, orchids are particularly dependent on fungi for their nutrition. During the walks we learnt to recognise a few common species of fungi.

Length of general meetings

We received feedback that the general meetings were finishing too late, this being inconvenient both to the more elderly and those having to travel. The suggested timing was put into practice at the June meeting. We didn’t manage to start strictly on time, but we kept the popular vote period to 15 minutes. We will be holding to a strict limit of 40 minutes for speakers so that meetings can be finished by 9:45 pm. Fortunately, the speaker was brief at the last meeting. Any further feedback is welcome and will be appreciated.

Committee meeting

The committee meeting administered the business of the society, considering such varied topics as starting an orchid seed bank and obtaining donations online through our websites. There was associated interesting discussion on progress with the seed kits project and plans to use orchid seed

viability tests to obtain seedlings for propagation. As always. minutes are available to those interested.

Spring Shows Volunteers needed

After being understaffed for the 2015 show we urgently need more volunteers for the NOSSA Spring Show on 17th & 18th September. Again for the Spring Show of the Australian Plant Society on 8th & 9th October helpers are required. Especially since four folk who

normally assist will not be available this year. Please volunteer if you can. These events are always a great way to spend a day or two.

Informal visit from Greg Steenbeeke

Greg Steenbeeke, recently editor of the ANOS (Australian Native Orchid Society) journal, Orchadian, visited Adelaide and stayed with us over the long weekend. He was keen to see our native plants and we took him out to see our bushland. As he wished to meet Steve Howard, we visited his greenhouse and went to Jenkins Scrub. Our family got on really well with Greg and Kerry and talked till midnight each day of their stay. We look forward to Greg talking at our August general meeting.

oooOOOooo

Scam emails

Scam emails have been doing the rounds again with some NOSSA members receiving such. NEVER click on any links and make sure you mark it as spam. Any emails from NOSSA will be specific and not vague. If there is a link in the email, then we would say what it is about – “not have a look at this”.

Park Passes

For eligible members these have been extended to the end of July. The secretary will be in contact with those concerned, with information pertaining to the new procedures.

Field Trip To Blewitt Springs Report Rosalind Miller

What an amazing day the members had on a recent NOSSA Field Trip to two sites near Blewitt Springs on Saturday 4th June 2016. The sun was shining on the group of eight, led by the knowledgeable Robert and Rosalie Lawrence.

To our great delight there were a large variety of orchids, some flowering, and some leaves. Since Tony and I only joined NOSSA last April, this was only our third NOSSA Field Trip. As usual Robert and Rosalie were a source of bush knowledge on a whole range of flora and fauna including the call of a fan-tail cuckoo, the gum leaf grasshopper, weed grass, the native cranberry, the rock fern, the sundew, native bees including nests in the ground and, of course, orchids.

The first site we visited was Hardy Scrub and the walk began with the discovery of some leaves of the purple cockatoo orchid Glossodia major by a budding orchid identifier, Rob Soergel. He pointed out quite a few different species during the day, quoting Robert Lawrence’s book “Start with the Leaves” as his “bible” for identification (It has become our “bible” too!). The second site was nearby at the Manning Flora and Fauna Reserve, owned by the SA Field Naturalists Association.

Both sites consist of white, sandy loam dominated by the pink gum (Euc. fasciculosa), desert banksia, (Banksia ornate) and an understory of bracken fern and heath. However, in Hardy Scrub, Robert pointed out an area, bereft of trees, that had been quarried when the dirt road was built.

Large colonies of Fire orchid (Pyrorchis nigricans) not yet flowering were seen at both sites. Most will not flower, but if they did flower in Spring, it would be a sight to behold! They were so dense in many places,

including the road, that it was very hard not to tread on them. Rosalie assured us that they were quite hardy.

After much hunting, the most common flowering species found at Hardy Scrub was the Blood Greenhood, Urochilus sanguineus. It was very interesting to see that specimens of this orchid could have single, two, three or multiple flowers and on one occasion there were two plants so close together that they could easily be mistaken for one divided specimen. There was even one specimen with four of its flowers all facing in one direction.

At Hardy Scrub, we all lined up to take photos of a large clump of eggs containing tadpoles yet to be hatched. Their little patch of water seemed to be drying up but with the recent rain we think they will be fine!

Sundews, both green and red coloured leaves, were everywhere with glistening dewdrops at the end of each rosette. They were so captivating. The contrast in colours between the green clubmoss and dainty little orange fungi was very striking.

Mosquito orchids (Acianthus pusillus) were still in flower and the Banded Greenhood (Bunochilus viriosus) was in bud. We also saw the tell-tale leaves of many varieties of orchids that should flower in Spring: King Spider (Arachnorchis tentaculata), Dwarf Greenhood (Linguella sp. Hills nana), Purple Cockatoo (Glossodia major), Mayfly (Nemacianthus caudatus), Maroon Hood (Pterostylis pedunculata) as well as at least two varieties of sun orchid, Thelymitra antennifera and possibly T. arenaria.

After enjoying lunch at a convenient picnic table at Hardy Scrub, some of us moved on to Manning Flora

and Fauna Reserve. As the soil type was similar, some of the orchids seen were the same as those in Hardy Scrub, such as Purple cockatoo, Mosquito, Blood Greenhood (Urochilus sanguineus) in flower and the aforementioned Fire orchids. Orchid species that we didn’t notice at Hardy Scrub were the Small Gnat (Cyrtostylis reniformis) Leek (Prasophyllum sp), Sun Orchid (Thelymitra brevifolia) and Midge (Corunastylis sp. Adelaide Hills) which had finished flowering. It was great to see the flowering mosquito orchids in dense colonies at this site.

A surprise on our part was that the little hole in the ground with lots of little beads of soil spreading out from it is caused by a native bee. Neither of us had any idea that bees also lived underground! A lovely end to a wonderful day was the sight of the colourful autumn grape vine leaves at the Southern end of Manning Reserve. We certainly had an extremely enjoyable day.

June Meeting Review

Rob Soergel (Assistant Editor)

Biological Control Program By Phil Cramond

The monthly meeting was well attended and there was a good display of plants with terrestrials making up the majority.

This month’s guest speaker Phil Cramond spoke about the use of biological agents for the control of pests (either plant or animal). He explained that bio control was not an eradication program but more a balance between a pest and its natural enemy. He presented a couple of examples which included Salvation Jane. This is attacked by crown weevils, flea beetles, root weevils and pollen beetles. Combined they have had a major impact on the Salvation Jane population. Another example he provided was that of the English Broom which is attacked by the Gall Mite which has helped reduce the numbers of this weed.

Robert Lawrence

Phil Cramond condensed a career worth of biological control into a fascinating half hour. He began by putting biological control into context; when a pest plant or animal has become too abundant to control economically it can be targeted for biological control with the aim of shifting the balance. By its nature biological control does not wipe out a pest for this would be counter-productive. Using a control agent coupled with integrated pest management the expense of biological control becomes soundly economic; often with dramatic results. He highlighted examples of controlling Salvation Jane, Gorse, Bridal Creeper and English Broom. Control of Boneseed may be starting to be effective but there is inadequate monitoring to determine if this is the case. Phil spoke very passionately about his topic and was keen to share his knowledge and even some of his control agents.

Protecting the Native Flora in Kuitpo Forest

Jenny Woodley

Kuitpo Forest provides an extremely valuable opportunity for us all to see many different species of native orchids (and other native flowers of course.) For 30 odd years my family and I have been able to spend many, many days enjoying all that this forest offers (picnics, school excursions, horse riding and bushwalking), particularly in the areas of Knott Hill, Mt Panorama and Iron Barks. I have always been interested in the variety of colours from the native flora that spring up at certain times of the year and in the last 10 years have developed a sense of the range of native flora that the forest offers. I have had the support of some of the ForestrySA staff to increase my interests in photography and native flora. Having this level of involvement and interest has helped me to become more committed to the protection of the native flora and fauna in the forest. Being a member of NOSSA has also opened new avenues of interest for me.

Recently, as a result of a request from a NOSSA committee member, I was able to work on behalf of NOSSA, with some of the staff of ForestrySA to help protect a valuable and precious area of native flora.

I liaised with the Conversation Planner of ForestrySA (Jackie) to see what could be done to keep horse riders from riding over the area of Knott Hill where a large number of orchids species grow and in particular “the ducks.”

Jackie and I had a long discussion about various options and she was able to consult with other relevant ForestrySA staff to see what could be done. As a result, temporary signs have been placed at each end of this special area and metal signs will replace them in coming weeks. The staff and those of us who go into this area will be able to monitor the effectiveness of these signs. It is also planned to reword the horse riding permits regarding staying on vehicle tracks to avoid trampling native vegetation.

It has been very rewarding for me to work with the relevant ForestrySA staff to look after such a valuable resource. I am sure that we will be able to develop more positive strategies when and if the need arises.

Seed Kits First Seedling Leaves

Les Nesbitt

On 11th June 2016, while still under the effects of a lingering cold, I felt much better after viewing 4

seedling leaves of Pterostylis sanguinea growing in my mother pot that supplied some of the seed for the kits. This was the first pot sown with fungus inoculated millet and orchid seed back in March 2016. It has taken almost 3 months for protocorms to form and then send up leaves. This is slower than in the lab at Kildare where the first leaves are visible after about 1 month in petri dishes. The first kits were sold at the March meeting so expect leaves to appear soon in these pots if they were sown immediately. Will hundreds of seedlings appear in the next 3 months?

Mixes for Pterostylis curta Les Nesbitt

In February 2016 three 125 mm pots of different mixes were prepared. Five small tubers of Ptst. curta were planted in each pot. Pot one contained 100% commercial native plant compost. Pot two held 50% native compost and 50% washed sand. Pot three was the control with my usual mix of 50% sand, 10% soil, 20% palm peat and 20% organic matter consisting of sieved native mix, pulverised gum leaves and seedling grade composted orchid bark plus a little blood & bone. The native mix for pot 3 was sieved to remove the larger lumps of pine bark over 5mm in size. Each pot was given a coded label and a topping of sheoak needles. The 3 pots were put side by side on a bench in a shade house on my block in the Adelaide Hills.

While this was a small sample the results indicate that 100% native mix is superior for Ptst. curta. Pot 1 is on the left in the photo and has 4 healthy leaf

rosettes albeit not large enough to flower this year. The 50% sand mix in the centre pot did not grow well at all. In the control pot 3 on the right, all 5 tubers grew but they are not as robust as pot 1.

Letters to the Editor

Editor: This month’s correspondence points out a number of errors in the last couple of journals. I thank the correspondents for taking the time to point them out. To leave them could only lead to confusion or further incorrect knowledge in the minds of our readers, and continue to perpetuate misinformation.

Remember anyone is welcome to make comments either positive, share a complaint , an error or ideas for improvement. Articles are always very welcome and a great way to learn more about orchids.

Erratum:

March Meeting Review - April 2016 Vol 40 No 3 p 29 “Hello Lorraine, I hope it's not too late to add this to the next edition, but I was wondering whether you could mention a small error in the last April Journal, on p 29, regarding the presentation I gave in March. The species should read ‘Caladenia rigida’ and ‘Glossodia major’, both using a wide range of pollinators. Thank you very much,” Renate Faast. Ed - Sorry Renate that it did not make it in to last month’s journal but I hope this sets things straight at last. New Orchid Species for SA - May 2016 Vol 40 No 4 p 45 “… the collage photo used for Bob’s article in the current Journal should have been attributed to June Niejalke. The photo Bob put in was the one taken by him, a number of years ago.” .TB The Orchid and Mycorrhiza Fungus Relationship- June 2016 Vol 40 No 5 p 57 Thelma Bridle pointed out that she “DID NOT review the final article before publication. It was “ a third party. Being “very particular about the facts being correct for anything to be printed “…The information regarding Dipodium species – somehow changed to Diplodium– was incorrect. I have attached the correct information as set out below” ... “I suppose I’m still worried about the rest of the article but I really don’t have the knowledge to comment” … “In any case Jack Warcup’s work was 30-40 years ago, so probably quite out of date.” “It’s really better to only write about things you know well without expert input.” Regards, Thelma. Thelma’s review of the first section of Orchid and Mycorrhiza Fungus Relationship All orchids are nutritionally dependent on fungi at the time of seed germination and some require fungal assistance at various times during their life cycle. In the Adelaide Hills two leafless orchid genera of Dipodium spp. (Hyacinth Orchids) rely totally for their nutrition on a mycorrhizal fungal association, as having no chlorophyll means photosynthesis does not take place. Fungi provide additional water and trace elements to many plant and tree species by spreading mycelium across large areas, and using the very fine hyphae for absorption and transporting to the plant. By the process of photosynthesis in the leaves sugars are formed, which trees then store in the trunk and branches. A small amount of the sugars are provided to the fungus as a reward. However, the parasitic hyacinth orchids D. roseum and D. pardalinum recruit the root-like hyphae of fungi into their own root cells thereby gaining first access to the sugars. Fungal associations of Dipodium species have not been studied in South Australia. Research in Queensland showed two East Coast species to be dependent on mycorrhizal relationships with Russulaceous truffle species. Above ground Russula spp. fruit bodies are frequently seen around stringybarks, so it is likely that SA species of Dipodium are also associated with Russulaceous truffles.

Editor’s Comment: Thank you Thelma for your concerns. I will endeavour to make sure that things are checked more thoroughly before going to print.

June 2016 Winning Orchid Picture

Rosalie Lawrence

It is always good to see other members submitting images for the competition. This month Rob Soergel entered Urochilus sanguineus growing with Bunochilus viriosus (1 below) and Ros Miller a Caladenia cairnsiana. Others were Rob and Jenny Pauley’s mass flowering of short Urochilus sanguineus, Pauline Meyers’ Arachnorchis cardiochila hybrid (possibly with A. strigosa) and Lorraine Badger’s Diuris corymbosa.

The winning picture taken by Ros Miller C. cairnsiana (Zebra Orchid) is one of Western Australia’s unique and interesting orchids. It was first collected by Baron Von Mueller (Victorian Government Botanist 1857–1873) from the Stirling Ranges and subsequently named in 1869 after the Rev Adam Cairns a Melbourne Presbyterian minister who promoted “various philanthropic studies”. In the 2000’s various synonyms were applied to the name, most notably Jonesiopsis cairnsiana (2003).

Many of the distinctive features of this species are readily seen in Ros’ picture – the non-clubbed, equidimensional short lateral sepals and petals which are hard pressed up against the ovary; the smooth, upswept labellum. What is not seen is the leaf which is erect large pale green with the bottom third usually irregularly blotched with red-purple.

Flowering from August to November, occasionally in clumps, these orchids are distributed over an extensive geographic area from Lancelin approximately 130 km north east of Perth, to Israelite Bay near Esperance some 775 km south

east. They grow in a range of habitats from forests, woodlands, to mallee heathlands.

Interestingly for such a widespread and colourful flower, they are often missed being seen as they are ‘small and hard to see’.
