Meeting commences at 7:30 p.m. 12 FEBRUARY MEETING Only one plant was benched in the Terrestrial Section and three in the Epiphyte Section. While this is less than that of some previous years it is likely a reflection of the hot dry summer we experienced. The terrestrial was Eriochilus cucullatus from Tasmania exhibited by David Pettifor with several flowers(larger than those of the South Australian Eriochilus). The epiphytes were; Judging results Dendrobium Annes Rainbow Surprise, 2nd D. Rozella 'Best', Sarcochilus Velvet 3rd and popular vote Sarcochilus ?Velvet 1st SPEAKERS Thelma Bridle began the talk and accompanying slide show with a reflection of last years conservation activities. One slide showed a large gathering of intrepid field trip participants all dressed in wet weather gear and it looked like it was certainly needed. The photos of the orchids were excellent and most were of rare or seldom seen species that are the subject of conservation and weeding outings. Cathy Houston followed Thelma's talk with slides of some of the major field trips of 2002 including a lovely photo of Remarkable Rocks on Kangaroo Island. Both speakers made me feel envious of those who attended the conservation & field trips when I wasn't able to and disappointed that I did not go on those I could have. FOR YOUR INFORMATION - NOSSA NEWS ANNUAL GENERAL MEETING Nominations are called for Vice president, Treasurer and one position on the committee. NEW MEMBERS NOSSA Committee and members warmly welcome new members; Andrew Pritchard, Neil Nillson and L. & R. Saunders. FOR SALE The following are offered by tender - to Bill Dear.

Fitzgerald 1882-1893 2 vols in excellent condition, bound in black leather with gold lettering. 13 PRESIDENTS REPORT It is with a good deal of pleasure that I present the Presidents Report for 2002. The year started with a very well attended 25th Anniversary Meeting and supper. It was fantastic to see so many foundation members and people who were involved in the formation of NOSSA. in 1977. There were many interesting and humorous stories and reminiscings from these older members which was greatly appreciated by the newer members. The season was very odd weather wise, with a cool summer followed by a very dry winter and spring. This was especially disappointing for the members who attended the many field trips and weeding days to see the number of flowering plants down on normal years. One of their highlights was a week's trip to K.I. Another high point of the year was a very successful Spring Show held in conjunction with the Australian Plant Society Spring flower show and sale. This was financially the best show for some years and gave us a greater exposure to the public. We should try to keep this as a combined event as both societies will benefit greatly. We again had a good mix of speakers of interest and well attended annual dinner and Xmas BBQ. Finally I would like to thank the hard working committee and everyone else who helped to keep NOSSA running smoothly and supported me over the last four years. I wish Bodo all the best for the next two years. BILL. Origin of Pterostylis arenicola tubers for NOSSA members Birgette Sorensen Pterostylis arenicola (sandhill greenhood) is an endangered, solitary orchid that is endemic to South Australia. This species was part of a research project conducted at Black Hill Flora Centre by Scientists Dr Manfred Jusaitis and Birgette Sorensen. Its habitat has been largely cleared, leaving three remnant populations; two of these populations occur to the south of Tailem Bend and the third population occurs in the Adelaide western suburbs. Seed was collected from each of the populations for germination trials. Seedlings resulting from the trials were potted up and grown in Dr R.S. Rogers shadehouse that was originally located at the Adelaide Botanic Gardens then to Black Hill Flora Reserve. When further research on the seedlings was completed, tubers were donated to Roy Hargreaves for distribution to several members of the Native Orchid Society of South Australia (NOSSA). The donated tubers originated from seed collected from the populations at Tailem Bend during the early 1990's. 14 NOSSA FIELD TRIP TO YORKE AND EYRE PENINSULAS - SEPT. 2001 PART 3: PORT LINCOLN AND THE EAST COAST Thelma Bridle [The editor apologises for the lengthy period between appearance of this part and parts 1-2] Only a short stop was made at Tod Reservoir as our local guides Hazel and Colin had more orchid-rich sites along Reservoir Drive to show us. Pterostylis plumosa occurred as both long and short bearded forms, unrelated to flower-size. P. nana was found in three different forms. A number of Thelymitra species were noted, all in bud, many would have been flowering on a warmer day. Colonies of T. benthamiana were numerous and very healthy, with much larger leaves than occur in the Adelaide Hills. The plants were still three-four weeks from flowering. On a hillside, Acianthus caudatus was found for the first time on Eyre Peninsula, with shorter segments than the Adelaide Hills form. P. aff. smaragdyna was an un- named, single flowered, self pollinated form and P. sanguinea were of the few- flowered type. Chamaescilla corymbosa (blue squill [lily]) were massed in large colonies and mauve flowers of Prostanthera spinosa [mint bush] were attractive. In a moist gully, orchids were in distinct colonies, large collections of single species of the more frequent orchid species. From here on and at several sites visited in the afternoon, T. epipactoides was opening a few greyish-blue flowers. We lunched at Wanilla Settlement Reserve, watching, appropriately, a pair of Port Lincoln parrots, now relegated to ringnecks along with all such parrots. A thornbill was busily collecting loose bark for nest building not far away, judging by the frequent returns. Two species of Microtis were found, one as yet not officially named, both T. antennifera and T. flexuosa were in flower, but T. x chasmogama was over. Prasophyllum aenigmum, whose small flowers never open fully, was out, P. aff. odoratum, a species specific to this site at Wanilla still in bud, P. fecundum in flower as was P. aff. fitzgeraldii. Specimens of this species were well perfumed, with deep coloured flowers and magenta stems. Wanilla Forest has been closed to the public since ownership transferred to the Aboriginal Community. We investigated the roadside vegetation along the perimeter. M. orbicularis was flowering, standing in water and P. nana, this time the swamp type in very moist soil. Under casuarinas a number of Caladenia species, Thelymitra species and some large clumps of P.

  • UV Reflectance but No Evidence for Colour Mimicry in a Putative Brood-Deceptive Orchid Corybas Cheesemanii
    Current Zoology 60 (1): 104–113, 2014 UV reflectance but no evidence for colour mimicry in a putative brood-deceptive orchid Corybas cheesemanii M. M. KELLY, A. C. GASKETT* School of Biological Sciences, The University of Auckland, Private Bag 92019, Auckland 1142, New Zealand Abstract Rewardless orchids attract pollinators by food, sexual, and brood-site mimicry, but other forms of sensory deception may also operate. Helmet orchids (Corybas, Nematoceras and related genera) are often assumed to be brood-site deceivers that mimic the colours and scents of mushrooms to fool female fungus gnats (Mycetophilidae) into attempting oviposition and polli- nating flowers. We sampled spectral reflectances and volatile odours of an endemic terrestrial New Zealand orchid Corybas cheesemanii, and co-occurring wild mushrooms. The orchid is scentless to humans and SPME GC-MS analyses did not detect any odours, but more sensitive methods may be required. The orchids reflected strongly across all visible wavelengths (300700nm) with peaks in the UV (~320nm), yellow-green (500600 nm) and red regions (650700 nm), whereas mushrooms and surrounding leaf litter reflected predominantly red and no UV. Rather than mimicking mushrooms, these orchids may attract pollinators by exploiting insects’ strong sensory bias for UV. Modelling spectral reflectances into a categorical fly vision model and a generic tetrachromat vision model provided very different results, but neither suggest any mimicry of mushrooms. However, these models require further assessment and data on fly spectral sensitivity to red wavelengths is lacking – a problem given the predominance of red, fly-pollinated flowers worldwide [Current Zoology 60 (1): 104113, 2014]. Keywords Diptera, Colour space, Fly pollination, Orchidaceae, Spectral reflectance, Visual modelling Flowers typically attract pollinators by advertising in the Orchidaceae, in which approximately one-third of rewards such as food (Chittka and Thompson, 2001; species do not reward their pollinators (Jersáková et al., Raguso, 2004).

  • Plant Life of Western Australia
    INTRODUCTION The characteristic features of the vegetation of Australia I. General Physiography At present the animals and plants of Australia are isolated from the rest of the world, except by way of the Torres Straits to New Guinea and southeast Asia. Even here adverse climatic conditions restrict or make it impossible for migration. Over a long period this isolation has meant that even what was common to the floras of the southern Asiatic Archipelago and Australia has become restricted to small areas. This resulted in an ever increasing divergence. As a consequence, Australia is a true island continent, with its own peculiar flora and fauna. As in southern Africa, Australia is largely an extensive plateau, although at a lower elevation. As in Africa too, the plateau increases gradually in height towards the east, culminating in a high ridge from which the land then drops steeply to a narrow coastal plain crossed by short rivers. On the west coast the plateau is only 00-00 m in height but there is usually an abrupt descent to the narrow coastal region. The plateau drops towards the center, and the major rivers flow into this depression. Fed from the high eastern margin of the plateau, these rivers run through low rainfall areas to the sea. While the tropical northern region is characterized by a wet summer and dry win- ter, the actual amount of rain is determined by additional factors. On the mountainous east coast the rainfall is high, while it diminishes with surprising rapidity towards the interior. Thus in New South Wales, the yearly rainfall at the edge of the plateau and the adjacent coast often reaches over 100 cm.

  • Management Plan Kaiserstuhl Conservation Park 2006
    Department for Environment and Heritage Management Plan Kaiserstuhl Conservation Park 2006 www.environment.sa.gov.au This plan of management was adopted on 11 January 2006 and was prepared in pursuance of section 38 of the National Parks and Wildlife Act 1972. Government of South Australia Published by the Department for Environment and Heritage, Adelaide, Australia © Department for Environment and Heritage, 2006 ISBN: 1 921018 887 Front cover photograph courtesy of Bernd Stoecker FRPS and reproduced with his permission This document may be cited as “Department for Environment and Heritage (2006) Kaiserstuhl Conservation Park Management Plan, Adelaide, South Australia” FOREWORD Kaiserstuhl Conservation Park is located approximately 80 kilometres north-east of Adelaide and approximately 12 kilometres south-east of Tanunda, in the northern Mount Lofty Ranges. The 392 hectare park was proclaimed in 1979 to conserve a remnant block of native vegetation, in particular the northern-most population of Brown Stringybark (Eucalyptus baxteri). Kaiserstuhl Conservation Park preserves a substantial number of habitats for native fauna and helps to protect the soil and watershed of Tanunda Creek. More than 360 species of native plant are found within the reserve, many of which are of conservation significance. Bird species of conservation significance recorded within the reserve include the Diamond Firetail, White-browed Treecreeper, Elegant Parrot and Crescent Honeyeater. Kaiserstuhl Conservation Park also has a rich cultural heritage. The reserve is of significance to the Peramangk people and Ngadjuri people who have traditional associations with the land. Kaiserstuhl Conservation Park has also been a valuable source of material for botanical research. Dr Ferdinand von Mueller and Dr Hans Herman Behr collected Barossa Ranges plants from the area between 1844 and 1851.
