Terrestrials

Acianthus pusillus, A. caudatus, Caladenia deformis, C. pusilla (flowering in flask), Chiloglottis aff. truncata, Ch. trullata, Corybas dilatatus, C. incurvus, Diuris pardina (SA form), D. orientis, Leporella (as a weed in pots), Pterostylis collina, P. curta, P. stricta, P. aff. cycnocephala (SA ), P. grandiflora, P. nana, P. nutans, P. ophioglossa, P. recurva, P. stricta.

The Dockrillia teretifolia were all different, had been mounted differently and treated differently, one with red leaves had probably been kept in bright sunshine; nevertheless all were very floriferous. The mild, dry and sunny conditions Adelaide suffered in July was the probable reason for early flowering of terrestrials and epiphytes alike.

63 LAST MONTH'S SPEAKER:

Our July speaker was Mark Clements from the Centre of Plant Diversity at the CSIRO in Canberra. Mark is originally from Adelaide. He gave an overview of his work, explaining how it has helped to sort out the of Australian orchids at all levels from species up to actual tribe.

This was probably the most interesting orchid talk 1 have ever attended as it answered so many questions at so many levels. Mark began with his work on symbiotic flasking of orchid seed, moved on to his work at Kew in 1984 and visits to all the great European herbaria. We then accompanied Mark (via slides) on trips to New Caledonia and New Guinea. From there we went via electron microscope into orchid seed embryos, electrophoresis, DNA sampling. From there we skipped over to Qld and the Cooktown orchids. Absolutely fascinating.

Anyone listening to Mark would have little trouble accepting the taxonomic outcomes of his work. This includes the reasons why Pterostylis is being divided into several genera and why the Cooktown orchid in general has become at least 5 species... ie D. bigibbum itself from the Cooktown area up to the Iron Range, D. lithacola from further south, D. phalaeonopsis from further north and D. striaenopsis.

We will even have to accept that almost none of the Aussie dendrobiums actually belong to Dendrobium sensu stricto and that perhaps none of our bulbophyllums will stay in the genus Bulbophyllum.

It was good to see Mark's family present including his parents who are well known conservation activists from a time before such issues were popular.

64 FIELD TRIP REPORT: PTEROSTYLIS SMARAGDINA SPECIAL JULY 24

This excursion to Scott Creek CP provided a feast of Winter orchids. We met President Tom Hand of the local Friends group at the main Park gate on Frith Road. There was exciting promise of things to come as within a metre of the gate were Diuris pardina and Thelymitra nuda in bud. A few metres further down the track were large plants of T. grandifl ora. This track, the Quarry track leads into the aptly named Greenhood Track where no less than 12 species of greenhood were found!

Not surprisingly the first of these was our quarry P. smaragdina growing with P. sanguinea, P. nutans and P. aff. nana all in full flower. The further we went the taller the P. smaragdina became! In fact this species is our tallest greenhood, reaching to l metre tall. (see Thelma's amusing illustration...." I can't see any greenhoods here!").

A few steps off the track we found an old mine tunnel (silver was mined here) and around it lots of Acianthus pusillus in late flower and A. caudatus just beginning to bloom. Some species like Genoplesium aff. rufum and Eriochilus sp. were long finished. We continued on to some of the best woodland vegetation in the park. Leaves of some 20 species were seen.... Acianthus, , Corybas, Caladenia (5 species), Diuris, Glossodia, Leptoceras, Microtis, Orthoceras, Prasophyllum, Pterostylis, and Thelymitra (6 species).

Greenhood Gully has the largest and densest colonies of Corybas dilatatus (diernenicus) in South Australia so we walked around the edge of these and not through them .... Amongst the short, ruby-red Corybas was a single flower of Pterostylis pedunculata flowering early as a result perhaps of herbicide used to kill blackberries here. We added a new record for the Park as a colony of Corybas x miscellus was located nearby. One of the most spectacular colonies of Pterostylis robusta we had ever seen was right by the track; some 50 plants in flower. Close by were dozens of P. plumosa in early bud and a rosette of Pterostylis aciculiformis.

At this point we were aware of the weather closing in and began to hurry but a call of 'here's a different one' had us rushing to look at Pterostylis aff. alata ( one of six undescribed taxa of this complex in SA). We just reached the road before the rain set in and now our objective was no longer orchids but our cars!

Most of us called it a day but some souls moved further into the Park and found Corybas unguiculatus, , Pt. aff. nana (mallee form) and P. aff. nutans in flower. For these people a total of seventeen orchid species in flower in July proved what a great orchid location Scott Creek is.

*This trip was repeated the next day and the same orchids seen as well as Leptoceras.

NOTE ON THE GENUS PTEROSTYLIS.

A recent article by the editor on the subject of our greenhoods being split into several genera prompted me to ask David Jones on his recent visit to SA just how many genera this would be. I won't tell you the number but it was actually larger than I had anticipated. Our July speaker also threw more light on the subject as he displayed a chart showing relationship of the various groups of Pterostylis as it is now known.

65 Mark also suggested that Caladenia may at some stage be divided farther but that this would require further work. His work so far actually indicates that Caladenia, Glossodia and 'Cyanicula' are more closely related than many of the Pterostylis groups so we may as well refer to Caladenia deformis for a while yet.

CULTIVATION OF TERRESTRIAL ORCHIDS :

Part 3 ....Deflasking by Les Nesbitt

Deflasking terrestrial orchids has always been a hit and miss affair. You would think that after 20 years it would be as easy as falling off a log. Not so.

ANOS-Vic have formed a group to study the problem and we should assist so that we may all learn. An opportunity to reproduce our rare and endangered orchids is going begging because although seedlings can be raised in flask the losses on planting out are still horrendous. A start was made at the NOSSA July 1998 meeting when members assisted in deflasking a number of different genera into various proven as well as experimental potting media. I have had a look at the pots from that effort and 60% of those pots contain no plants this year. They say we learn more from our mistakes...

Successes:

Pterostylis cucullata planted into sphagnum moss have come up again. Likewise with some Diuris and Thelymitra but in low numbers. Diuris and Thelymitra planted into normal soil mix and which had the agar washed off, are growing well.

Failures:

• large clumps of seedlings put out with the agar still attached quickly went mouldy and all were lost. • No plants in the peatmoss and vermiculite survived the very hot, dry summer of 98-99. This mix is very difficult to wet again once dried out. • No plants in pure sand survived the summer. • This winter blackbirds are digging in the peat-moss pots looking for worms and destroying the orchids.

So what to try this summer: • Definitely wash off all agar! • Break plants into small clumps and place around edge of pot and pour the mix into the middle. Level this to just cover the base of the seedlings and not over the leaves. • Use normal soil mix only. • Use a pine needle topping. • Plant out at various times from May to September. • Wait until rain is forecast or water thoroughly at once. • Compots put straight into the shade-house to get rain and dew.

Seedlings in some pots planted out earlier are growing beautifully while some just sit there unchanged and one hopes they are forming tubers. Some planted in the depth of Winter just rotted away. Those orchids which like heavy soils like Diuris and Thelymitra respond best to my methods. Perhaps I should try Caladenia and Pterostylis under drier conditions.

66 NEW MEMBERS GROUP / OPEN DAY

A meeting of the above groups will be held on Saturday September 25th at the home of Bub & Don Wells at 86 Pitman Rd Windsor Gardens. We will be mounting epiphytes on various media. Some lithophytes too. All necessary items will be supplied and a small charge will be made for plants which have been purchased for the day. It is imperative that bookings be made for this event which will commence at 2pm. Ring 82616030 or 0416095095.

SPRING SHOW

*Please let our Show Marshall know at the next meeting how much space you will need at the show. Consignment and plant labels available at next meeting.

FIELD TRIP REPORT - NORTON SUMMIT AND MORIALTA 17/7/99 by Thelma Bridle

Eight members ignored the forecast of rain and met at Norton Summit to explore the hillside which rises behind the pretty little local stone church of St. John. Although only a small area this hillside supports at least 12 species of orchid in large colonies. We determined the Pterostylis longifolia to be the recently named P. smaragdyna, with a bright green stripe down the centre of the labellum and a boldly striped hood. On a few flowers the stripe on the labellum was rather brown, but this appeared to occur in flowers just past their best. Many Eriochilus cucullatus, with their now large leaves, leaf development continues after flowering, were found with seedpods.

Thelymitra sp. had also seeded prolifically with many small leaves forming a large colony. A huge colony of Acianthus pusillus had a mass of flowering spikes, difficult to avoid stepping on these, and Pterostylis nana - the 'Adelaide Hills' variety, with hairy stems and long dorsal was numerous. After a coffee break we journeyed on to Moore's Road which leads to the higher ground of Morialta Conservation Park. Walking along the continuation of the road, inside the park we found 17 different species of orchid. Many native shrubs were coming into flower. Epacris impressa, in all shades of pink were everywhere, with Astroloma conostephoides more common along the road verges. Grevillea laverululaceae here had large deep pink flowers. Tetratheca pilosa and Hvbanthus were both in flower. Many Drosera whittakeri were open in the sunshine and the odd light shower. Orchid leaves and buds were everywhere, but only Pterostylis sanguinea and P. nana were in flower. Buds were found for Pyrorchis nigricans, Caladenia tentaculata, Glossodia major, Cyrtostylis reniformis and Pterostylis plumosa. Many of the Eriochilus cucullatus here also had seedpods. It seems to have been a very successful season for the pollination of Eriochilus.

67 AUSTRALIAN NATIVE DENDROBIUMS 31

DOCKRILLIA STRIOLATA (STRIATED ROCK ORCHID) BY MARK PHILLIPS

First described as Dendrobium striolatum by HG Reichenbach in 1857 from plants cultivated in Europe!

Other names include Dendrobium milliganii F. Muell. For the Tasmanian and Bass Strait Islands form which is now known as Docrillia striolata ssp. chrysantha.

As the common name suggests D. striolata is a Lithophyte which forms large, often dense clumps which may cover entire boulders or hang in metre long strands off cliff faces. The species is widespread in the coastal strip from the Barrington Tops in the north. to eastern and . The leaves are thick and fleshy, curved and up to 30cm long. They often turn reddish in well lit sites.

Aerial roots are freely produced.

Flowers are about 2 cm across in ones and twos and coloured white, green and yellowish. with distinctive red stripes near the tepal bases. Perfume is sweet and strong at times in warm weather.

Unfortunately flowering is often sparse otherwise this would be more popular with growers. Easily grown in a hanging basket or mounted on various hosts. Plants require bright light, humidity and air movement.

WEEDING TRIP REPORT - HALBURY SCRUB 10/7/99 by Thelma Bridle

Only a few members turned up for weeding at Halbury Scrub. The weather was a vast improvement from last year's rain, so we were able to treat a lot of bridal creeper with our weeding wands. Previous weeding had been very successful with only seedlings to treat in some areas. Some plants appeared very strange - a cluster of short stems with dwarf yellowy-green leaves, presumably a result of poisoning. Re-treatment should now see their demise.

Some heavily infested areas were sprayed by TPAG as the bridal creeper was smothering all other growth. It was pleasing to see our efforts rewarded with diminishing bridal creeper, although there is plenty to keep us busy at this site for a number of years. Many orchid leaves were found - Caladenia verrucosa, C. stricta, C. tensa, Thelymitra sp., Cyrtostylis reniformis, Acianthus sp. and a couple of spent flowers of Genoplesium nigricans. There were many Pterostylis sp. rosettes. P. "Halbury" were in bud, P. pusilla and P. excelsa

68 which Bob Bates determined had crossed with P. dolichochila many generations earlier, was well photographed. Mid-afternoon half the group travelled on to Clare to visit Neagles Rock. This is an isolated rocky outcrop of remnant bushland situated just out of Clare, and after a steep climb, affording excellent views over the Clare valley.

Orchid numbers here were amazing for such a small area. We found a large variety and number of Thelymitra sp. leaves, Glossodia major, Caladenia sp. and Diuris behrii leaves. This should make an interesting site to visit on our field trip to the Clare area in early October. Flowering all over the west-facing slope were Pterostylis robusta. We found 4 variations in size and appearance, ranging from a short, pale flower to a colony of 10 flowering plants over 13 tall - see illustration below.
