Our epiphyte commentator pointed out that all plants were growing in small plastic pots just the way epiphytes like it! They do best if pot bound. One clever grower had inserted the plastic pots inside more attractive clay pots which stopped the plants tipping over. An interesting Australasian hybrid on display was Dendrobium canaliculatum x D. atroviolaceum (A New Guinea species). The pot of Glossodia on display was quite spectacular: 30 plants, most in flower. This is quite an achievement as Glossodia are notoriously difficult and normally flower 2 months later. To top it off the pot had been 8 days at the John Martins Orchid Show and apart from a few bent stems they looked great. The owner has had the pot untouched for several years. The first plants from the Kuitpo rescue dig last December were present. These were Corybas which shared features of C. dilatatus and C. incurvus. They may have been hybrids (C. x miscellus). This hybrid often occurs in pine forests. The three very different Pterostylis nana on display were a good indication that several species were involved. Our commentator suggested there may be 20 to 30 species at present lumped under the one name!

DENDROBIUM x kestevenii x tetragonum x suffusum by GEOFF EDWARDS I did not win this plant in a raffle (as suggested at the July meeting) but bought it at an Orchid Club of SA trading table for $5 last November. Having never seen the cross before, or even heard of D. kestevenii, but being attracted by the description - star shape, green, red spots, frequent flowering - I decided to give it a go even if the 20 canes, approximately 40cm high, in a 12cm black round plastic pot did not look over inspiring.

It was at worst another pot to slowly fill my extended shadehouse. I hung the pot from a top rafter so that it was about six feet off the ground. Open to all elements, mottled shade was provided during the majority of daylight hours, 64 some direct sunlight occasionally coming between the gum trees. Ample air movement is available as is natural rain when it falls.

Living at Bellevue Heights our place is on the southern side of the range overlooking the Sturt Gorge. Sheltered from the north but reasonably open to the south and west I find the area is slightly cooler and wetter than the Plains, with less direct light all year round. The open bark potting mix allows good drainage in the wet, cold winter but closer attention is required with watering in the summer. Sometime between buying and showing the plant I put a handful of Dynamic Lifter on the pot (not scientifically decided but because I suddenly found some available time).

Then spikes appeared. Ten in all, eventually averaging six flowers per spike with flowers approximately 7cm x 4cm in size, and exactly as described. I took the plant to the June NOSSA meeting but not all flowers were open and their heads hung down. Two days in my office (air conditioned) for my staff to enjoy then the pot sat in our lounge warmed by the gas heater some nights. All flowers opened and looked up.

At the June meeting I learnt from Reg Shooter that D. x kestevenii was an early synonym for the plant now known as D. x delicatum. Upton's Dendrobium Orchids of Australia tells me that the original plant from which D. kestevenii was named (after Doctor Kesteven to whom it was given) was collected in 1930 from Alum Mountain in New South Wales. The star shaped flower of the D. tetragonum is predominant in my plant.

On the night of the July meeting a last minute rush and discussion with Pauline brought about the decision to take it in, The rest is history. Popular vote.!

As I frequently say, these plants survive in the wild without pampering. They need to be tough to survive in my environment.

JULY'S SPEAKERS Karen Possingham who was originally set down to speak about the work of the Conservation Group was unable to attend as she now attends Burnside council meetings on Tuesdays (as a councillor). Our new conservation officer, Greg Moss, gave a quick summary of the group's activities which range from working on endangered species, to weeding and public education. Bob Bates filled in the details and gave a bit of history. The group has been in action since 1982. We were fortunate to have the initiator of the NOSSA Conservation sub-committee present (Mrs Margaret Fuller).

THE CONSERVATION GROUP NEEDS MORE MEMBERS!

OPEN DAY SUNDAY JULY 2nd. by JOHN PEACE The open day for July was held at the home of Noel and Melva Oliver. Noel is well known as a grower and also a judge of native Australian and other orchids. Noel has a wealth of knowledge on growing orchids and is always willing to share his advice. He has two glasshouses, one is heated to a minimum temperature of 12°C through the winter months. In this he grows his hot-cold Dendrobiums and other tropical genera, he has fitted sprinkler systems using rain water only, probably one of the reasons why his plants look so healthy. Noel has quite an extensive shade house very neatly laid out, the benches are quite low to the ground for extra humidity, he also has quite a large collection of Sarcochilus, both species and hybrids, which he grows very well. Noel gave us a demonstration on how he repots and divides his plants. We finished off with afternoon tea. Thank you Noel and Melva for allowing us the opportunity to look around your orchid collection.

FIELD TRIP REPORT: HALE & MT CRAWFORD, JULY 16th by G. GUIDE After 80mm of rain in the week before this trip you'd think the clouds were empty: but no it poured all the way to Williamstown. About 20 (very keen) members met by the rushing creek outside the caravan park and proceeded to the eastern gate of Hale Conservation Park where it appropriately stopped raining. The scrub was ablaze with flame heath (Astroloma), golden Hibbertia and lilac Thryptomene. Unfortunately the flame heath wasn't putting out much heat! 65

We walked to the summit ridge admiring hundreds of Pterostylis sanguinea. P. robusta and P. nana along the track. A huge Agaric toadstool drew lots of attention. This toadstool was about 1000 times bigger than the tiny Corybas dilatatus hiding under gum leaves nearby. On the summit ridge itself there was a large variety of orchids, some species in thousands. Acianthus, Cyrtostylis, Genoplesium (in seed), and in addition to the Pterostylis already mentioned other greenhoods included P. longifolia, P. alata and hybrids. We had to pass about 10 000 rosettes of P. alata before we found the first flowers probably due to last year's drought.

The colony of the endangered Pterostylis aff. nana "Hale" on the edge of the track was doing very well. Some NOSSA members hand pollinated flowers last year and hopefully new colonies will result. Like many endangered orchids they are rarely pollinated naturally. Upon our returning to the cars it began to rain again. We drove to Mt Crawford South for a wet picnic lunch in the Pine forest, This site is one of the coldest in SA regularly going to - 5°C minimum and rarely exceeding 14°C in July! Yet in the deep shade and cold on the south side of the mountain were huge colonies of the helmet orchid Corybas incurvus. We searched in vain for the albino ones which grow here, passing a huge colony of Pterostylis curta and lots of Pterostylis robusta and Acianthus.

An interesting find here was a patch of the recently named native lily Wurmbea (Anguillaria) latifolia spp. vanessa, named in honour of your assistant editor Vanessa Maloney! These are closely related to the early nancies W. dioica but rather more attractive! The pristine white flowers have two purple nectaries on each petal and there are separate male and female plants. Due to the soggy conditions and washed out road we did not do the promised Watts Gully walk but we had seen plenty already,

FAVOURITE ORCHID LOCATIONS: OULNINA PARK by R. BATES Four years ago Thelma Hall of the South Australian Field Naturalists rang me to ask what Leek orchid she had seen on Oulnina Park (sheep station) via Mannahill on the Yunta - Broken Hill road. I told her I was surprised there were any orchids there but guessed from her description that it was the inland form of Prasophyllum odoratum. Since then I have been to Oulnina Park twice and fallen in love with the place. Driving south from Manna Hill across the saltbush flats, most of it looking dead in early October I held little hope of finding any orchids, the round grey hills in the distance seemed to hold little promise either. Once the road entered the hills however the scenery began to change. The lower slopes were covered with Triodia with here and there clumps of native pines. The road entered a dry creek bed lined with gum trees and a stop was made. We walked into the first patch of Triodia and to our amazement sticking up through the spiky tussocks of this desert grass were hundreds of tall leek orchids with fragrant 66 purple and white flowers similar to Prasophyllum odoratum but larger, the flowers crowded, the labellum not much curved. The further we went the more we saw - they were on the flats, north facing slopes, around rocks and on the ridges - there must have been a million of them altogether, Some in shallow soil had shrivelled up in the heat. (*note that this desert form is likely to be named as a distinct subspecies, perhaps 'ssp. eremea' = desert lover would be appropriate).

The further into the hills we went the prettier the scenery became - mixed open grassland - pines - gums and sheoaks with numerous creeks and isolated rock outcrops and cliffs. Very parklike (hence the name Oulnina Park). Under the pines were two different species of rufa group Pterostylis, both of them new to us and likely to be described as new species! If that wasn't enough, on the cliff ledges was a third new species of rufa group related to P. boormanii There were wildflowers everywhere - mostly daisies. We hiked for hours through the warm sunshine and located a patch of Microtis in a seepage area (in addition to more of the previous species).

The following year we returned in August to check for early flowered orchids and climbed to the summit of Oulnina Hill. There were occasional Pterostylis mutica in sheltered spots and near the summit a colony of P. robusta. The view from the top was spectacular. The Hills don't look high when approached from the north but the drop away to the south is about 1000 feet and very steep.

On the return walk we located a single Caladenia toxochila. ( Apparently sheep do more damage to Caladenia than to the other genera.) I would like to see the area made into a conservation park or at least have most of the sheep removed. The owners just might make more money from tourists, campers and the like than they do from sheep. Oulnina Park is the best area for orchids in the desert areas of our Eastern region and perhaps the most picturesque part of the region (on par with Old Boolcoomatta and the Plumbago granites but quite different!)

P.S. If you intend to camp in the area contact the owners first.

AN EVENING WITH IAN SAINT GEORGE On August 1st several NOSSA members were fortunate to meet with New Zealand native orchid identity Ian Saint George. Doctor Saint George was here for three days at a medical convention. He lives in Wellington, the heart of New Zealand orchid research and is editor of the New Zealand Native Orchid Society Journal so basically he keeps the far flung 125 members of the New Zealand group together. Ian was co-author with Doug McCrae (who we also met in Adelaide about 6 years ago) of the book "New Zealand Orchids: natural history and cultivation." He is currently working an a book dealing with all the New Zealand native orchids and on the publication of several undescribed Corybas and Thelymitra. He is working with Brian Molloy in New Zealand and David Jones in Canberra. We were treated to a selection of slides of the New Zealand species including a number of the recently recognised Taxa. Ian explained how NZ lay within a belt of prevailing winds which blew orchid seed across from Australia and pointed out that most of their rarest species are little more than temporary introductions from Australia. Their Chiloglottis valida and C. formicifera for example cannot expand their populations simply because the thynnid wasps which pollinate these species do not occur in NZ. Because of the paucity of insects in NZ most of their species are self pollinated. Ian thanked members of the Conservation group who had taken him up to Belair Recreation Park and showed a selection of 10 or so winter flowered orchids of the Adelaide Hills. We were then treated to a tour of Les Nesbitt 's orchid flasking laboratory.

BOTANISTS OF THE ORCHIDS No. 28 by MARK PHILIPS Kenneth MacPherson 1914 - 1995. Orchid lovers of Queensland mourn the recent passing of Ken MacPherson. Ken was born in Proserpine and grew up on a cane farm. His love of nature was awakened by his teacher Miss K Jurd. While supplementing his income from the farm he developed an interest in bookkeeping. This necessitated a better understanding of the local flora and led to an interest in orchids.

Ken was in the Australian military forces from 1938 - 1944 . He married his wife Anne in 1945 and began a new farm at Sinclair Bay. His property was called Gloucester Park, a name later to be used on his famous line hybrids. After the loss of his farm (due to natural disasters) he worked as Parks and Gardens curator for the local council for 25 years. 67

Ken obtained his first orchid (a Cattleya) in 1930 and grew exotic species for many years whilst developing his interest in native species. By 1936 he had found 46 species locally including two new species sent to Rupp and named by that orchidologist as Cleisostoma orbiculare and Bulbophyllum macphersonii. Ken wrote to C.T. White, Rupp and R.S. Rogers on a regular basis. Many of his collections are in the Queensland herbarium but a few are in Adelaide.

In the 1950's Ken began a program of hybridising using Dendrobium discolor., registering D. Gloucester Sands in 1963, at the time of his death he had made 1500 hybrids, 49 of them registered Dendrobium crosses.

In 1963 Ken became foundation president of the Proserpine Orchid Society and later life member. He was honorary member of ANOS Mackay, Ken was a speaker at many conferences and received many awards including the Australian Orchid Foundation Award of Honour in 1992. His orchid house was always open to visitors and though he was highly dogmatic and opinionated this was tempered by a congenial sense of humour.

Orchids discovered by Ken MacPherson or named after him include Bulbophyllum macphersonii and Cleisostoma orbiculare.

AUSTRALIAN DENDROBIUMS No. 13 Adapted from ANOS McArthur Newsletter, July 1995. by Len Field Dendrobium carrii Rupp - first discovered on Mount Spurgeon North Queensland by T.C. White and T. Carr in 1936 and named in 1937 by Rev. Rupp and C.T. White in honour of one of the discoverers. Confined to an area between Cooktown and Innisfail it grows on the outer branches of high trees in the cloud forests of the Highlands often in exposed and windy conditions. It is a true epiphyte and is seldom recorded as growing on rocks. The bulbs are spaced well apart with flowers cream to white with a yellow lip and red spotting on it. Flowering period is late winter to spring.

Cultivation: Although slow to establish it should be tied tightly to a slab. Air movement is essential with constant misting and watering in summer. It will not stand really low temperature in winter minimum warmth is needed (at least 5 degrees).

NEW ZEALAND HELMET ORCHIDS Second in a series adapted from the article- Corybas in New Zealand by Dan Hatch (The NZ Native Orchid Group Journal, 1994). CORYBAS CHEESEMANII O. KUNTZE REV. GEN. PLANT (1891) Corysanthes cheesemanii Named for T.F. Cheeseman, for 50 years curator of the Auckland Museum. First discovered by Thomas Kirk at Blockhouse Bay on the Manukau harbour, this is the only NZ species with two closed conical spurs at the base of the labellum and so is easily identified. It was included by Rupp (who was 'lumping'), in the related C. aconitiflorus, and this arrangement was followed by Hatch and later by Lucy Moore. Australian botanists are now tending to 'split' (the pendulum swings), and C. cheesemannii is in favour again. Corybas cheesemanii, while normally a green leaved plant with flowers borne above the surface, becomes on occasion saprophytic, loses its leaf and chlorophyll, and the flower does not rise above the surface litter. In this condition it can be confused with C. cryptanthus, so look for the conical spurs. Distribution: North Island and the Sounds/Nelson district of the South Island. In the north it prefers mature kanuka/manuka scrub, or taraire forest. Flowers: May-August.

CORYBAS CRYPTANTHUS Hatch (1956) = hidden flower Syn. C. saprophyticus Hatch TRSNZ 79: 366.t71 (1952) -not of Schlechter. Described from material collected in the Dome Valley north of Warkworth, by Bruce Irwin and Owen Gibson in October 1994 and supplemented by Hatch, this plant had been gathered on several occasions back to 1880, but was never properly understood or described. C. cryptanthus lacks chlorophyll and an expanded leaf, and the relatively large flower does not usually appear above the moss and litter in which the rhizome lives. Consequently, unless discovered by accident (such as being sat on for lunch!), the first indication of the species' presence is the tall, leafless, red-flecked seeding peduncle. Some flowers however, lack the red pigment, in which case the peduncles are also colourless, but always of course without an expanded basal leaf. This can be confusing when the plant grows, as it sometimes does, with C. cheesemanii. Minute rudimentary tubers are present in the axils of the rhizome bracts, but seldom develop. As pointed out in the introduction, the petals in this species are longer and more robust than the lateral sepals, and this has caused confusion in the taxonomic descriptions of both Hatch and Lucy Moore, where the petals are referred to erroneously as sepals. Checking my original illustration I find that I did draw it correctly, showing the longer petals arising from the rear pair of ovary ribs. The error lay in my interpretation.

When the flower is fertilised the elongating peduncle, in order to protect the developing ovary, bows its head so to speak and shoves upwards with its shoulders, straightening out once it is clear of the clutter. This bending over of the growing shoot, familiar for example in sprouting beans and podocarps, has been recorded in Corybas cryptanthus plants from Eastbourne, Wellington, and the Oxford State Forest in Canterbury. In the other species which open their flowers above the surface and are protected in the bud by both the floral bract and the folded leaf, the peduncle grows straight up.

Recorded habitats are manuka scrub, sometimes shared with C. cheesemanii, and beech forest (Nothofagus so/andri and occasionally fusca),often in company with C. trilobus. Distribution:North and South Islands. Flowers: July-August. 69
