A talk by Beatrice Hale, author of The New Zealand Pleasure Garden (2004). The speaker writes: "I want to explore the myriad purposes of plants- their purposes and our purposes.

 
I want to take you on a personal journey beyond the plants in our gardens to discuss the excitement of their origins, their journeys to New Zealand, and their value to us. The New Zealand Pleasure Garden is about how we can use our plants beyond the usual picking, cooking and potpourri activities. It is about making a garden for all the senses, vision, taste, touch, hearing and fragrance; it is also about what lies beyond. What else can we do with our plants? Touch them and feel their differences. Travel mentally by reading, time travel by looking into histories of plants and explorers. Exploit the beauty and endless fascination of plants to create pictures, jewellery.....
 
I want to explore what plants do for us - the wonder of planting and growing for people with disabilities - for people who are older - for migrants who want reminders of home.....
 
I want to explore the endless possibilities of plants."

A modern taxonomist in a postmodern era Servant or Master? A talk by Henry Connor, DSc, FRSNZ, co-author of Flora of New Zealand Volume V, Grasses. The pinnacle of botanical research is taxonomy; every subdiscipline is its contributor. Most users of the outcomes of taxonomic endeavour look for a binomial of convenience. Is this an appropriate outcome? Or are taxonomists just targets of attack over the lack of monophyleticism or the presence of paraphyleticism? A modern taxonomist will attempt some answers to modern problems, but will emphasise the amount of tedious work that lacks the modern appeal of DNA sequencing, cladograms and prominence in every botanical journal. In Castle 1 Lecture Theatre. For those that wish to join us, dinner will follow at Eureka Café and Bar, 116 Albany Street Dunedin.

A talk by Dave Kelly, University of Canterbury. In an important paper, Clout & Hay (1989, New Zealand Journal of Ecology Supplement) argued that the bird-plant interaction most at risk in modern New Zealand was that of seed dispersal, especially for large-seeded trees dependent on the kereru. In this talk I review progress on this subject in the 15 years since their paper was published, and show that both pollination and dispersal are at some risk, but for different reasons. Despite extensive work on these topics, there are still some very important questions that we have only the beginnings of answers to. Some of these tentative answers are outlined, and predictions are made about the true state of mutualisms. I also review to what extent the birds depend on the plants, as well as the plants depending on the birds. At the NEW Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel. Use the main entrance of the Benham Building to get in and go to the Benham Seminar Room, Rm. 215, 2nd floor. Please be prompt as we have to hold the door open. The 2004 Leonard Cockayne Memorial Lecture lecture, that Dave will be giving the following day in Dunedin is entitled "Plant reproductive biology in New Zealand: masting, mutualisms and mistletoes". That talk will be on at 12 noon the 6th October, in the Hutton Theatre, Otago Museum, 419 Great King St, Dunedin

A trip lead by Dr. Lisa Russell, Teaching Fellow in Botany. The intertidal zone (region between high and low tides) is particularly stressful for for seaweed growth. Despite this however, there is a high diversity of species found within this zone on southern beaches around the Otago coast. Providing the weather is calm we will be heading to Shag Point to look at some diverse rocky platforms. Shag Point is a region of special conservation value not only in relation to marine species but also rare terrestrial species. It is also the site of one of New Zealand's few underwater coalmines. We will also look at the nearby reef at Moeraki where the intertidal seaweed community has been replaced by the invasive kelp Undaria and discuss some of the implications this species might have on our native species. If the weather is not so good we will head out closer to home to the rocky shore at Brighton, where there is a diverse seaweed community comprising of a number of species which are only found in South Australia and southern New Zealand. Including a large number of seaweeds that are made up of a single cell but display a wide range of morphological forms. You will be surprised what a single cell can do! People should bring gum boots if they want their feet to remain dry. Also lunch, hat, warm wind-proof and/or water-proof clothing. Basically we'll be doing a bit of wading bacause the tide is not a very low one. Meet at the Botany carpark at 9:30 AM. Contact Lisa Russell on 479 9061 (w) or Ian Radford as below.

Trip to Southland Community Nursery, Otatara, Invercargill. Chris and Brian Rance have established what they have called a "Community Nursery". The aim of this nursery is to provide facilities and materials (potting mix, pots etc) to help people to grow local endemic plants and to restore vegetation of the local areas. Brian and Chris have lots of experience in growing native plants from seed and cuttings and are willing to share their knowledge. They are restoring native forest areas on their own property, have created a variety of shelterbelts using native plants and are creating a pond habitat. The have also established a threatened plants garden to provide sanctuary to over 70 New Zealand native under threat of extinction in the wild on their property. On the trip we will have a look at the nursery itself, the Threated plant garden and one or two of their restoration works. Chris or Brian will be there to give us a background about the nursery and the associated works. Leave Botany car park at 8 AM and return mid to late afternoon. Pack lunch, water and protection from the sun, wind, rain and cold. The possibility of extra side trips and an overnight option is still being investigated. For more information about the trip contact Ian Radford on 472 7470 (ah) or 479 9065 (w).

A talk by David Lyttle. The New Zealand alpine flora contains a diverse assemblage of species many of which are desirable and challenging horticultural subjects. Unfortunately New Zealand alpines are often appreciated more overseas than in their own country. This talk will provide an introduction to the propagation of New Zealand alpine plants from seeds and cuttings and will discuss problems frequently encountered in their culture. At the NEW Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel.

Trip to Tavora Reserve (Bobby's Head), with Pat Mark. Tavora Reserve is the site of a restoration project undertaken by the Yellow Eyed Penguin Trust, to return former grazing land, pine forest and patches of remnant vegetation back to native bush. This is both to provide nesting habitat for the Yellow Eyed Penguin, and to restore vegetation for its own sake. The Trust is keen that this is a working BSO field trip: they want us to test a trail guide that they have been developing for the Reserve, in addition to the normal compilation of species lists and any advice we can provide on restoration works. The Reserve provides a diverse array of botanical habitats, and can be divided into hillside, dune and wetland/riparian vegetation types. Of special interest are remnant Poa cita, Bulbinella augustifolia and a local speargrass Aciphylla glaucescens in the hillside zone; the cushion plant Scleranthus biflorus and sand convolvulus Calystegia soldanella associated with sand dunes; and stream edge plants including the salt tolerant Apium prostratum - native celery, Azolla filiculoides - red water fern, Cotula coronopifolia - bachelor's buttons, Leptinella dioica, Mimulus repens - saltmarsh musk, Shoenoplectus pungens - three square sedge, Sarcocornia quinqueflora - glasswort, Samolus repens - sea primrose, Selliera radicans and Puccinellia sp. - salt grass. The Trust has undertaken extensive plantings to try to reintroduce plants formally endemic to coastal hillsides, sand dunes and wetlands and welcomes feedback from the BSO on the restoration job they have done so far. Leave Botany car park at 9 AM Sunday and return mid to late afternoon. Pack lunch, water and protection from the sun, wind, rain and cold.

A talk by Lisa Russell. The taxonomy of the New Zealand members of red algal genus Pachymenia J.Agardh (Halymeniaceae, Rhodophyta) has been contentious. Three New Zealand endemic species of are currently recognized: one prostrate species P. crassa and two foliose species P. laciniata and P. lusoria. As part of my PhD I have explored relationships between these New Zealand species, in particular between the intertidal species P. lusoria and P. laciniata in order to develop a clearer understanding of species boundaries. A multidisciplinary approach was undertaken combining molecular systematics and cell wall chemistry with more traditional approaches based on gross morphological characters. I will discuss here the results of these three approaches, firstly in relation to the New Zealand species of Pachymenia and secondly in relation to the generic boundaries between Pachymenia and a sister genus Aeodes.

Morning Field Trip to Moores Bush, followed by afternoon cryptogam identification workshop. Moores Bush, in the upper Leith Valley, is the site of an on-going Forest and Bird restoration project, returning what was once dairy pasture to native forest. Their main emphasis now is in creating a mammal-free 'mini-mainland island' to aid the regeneration of podocarps. Miro, matai, totara, kahikatea and mountain cedar are all present, with some magnificent specimens towering above the vigorously regenerating under-story. Our main aim will be to help update the lichen, bryophyte and fern lists. Cryptogam (non-flowering plants) specimens needing identification will be brought back to the laboratory for the afternoon workshop in the Botany Dept. Lichen leaders Allison Knight and Jennifer Bannister, mosses - Maia Mistral. Leave Botany car park at 9:30 AM. Bring hand lens and lunch.

Guest speaker Associate Professor Helen Leach, an anthropologist with a special interest in palaeoethnobotany. When Dr Monkhouse described Maori gardens seen in 1769 as "completely cleared of all weeds", did he mean that the gardeners were fastidious weeders, or were there just fewer weeds to eradicate? Did the Maori and other Polynesian peoples have a concept of weeds equivalent to that in European languages? This talk will look at indigenous plants that might have invaded Maori gardens, the inadvertent introduction of a small number of fellow travelers with Maori cultigens, and how different groups of Polynesians might have classified the plants that we call 'weeds'.

Full day or weekend field trip to the Rock and Pillar Range with alpine research botanists and ecologists. For the fit there is the option of a 3-4 hr walk up through changing vegetation zones from lowland pasture/tussock/scrub, through subalpine tussock with regenerating Hebe right up to Celmisia-dominated alpine herb fields and lichen-rich cushion fields. On-going botanical and ecological research has been based in this area for over 50 years, often using the Otago Tramping and Mountaineering Club hut, 'Leaning Lodge' as a base and refuge. See www.botany.otago.ac.nz/alpine/. There's an opportunity for those keen to extend their appreciation of the alpine flora to stay overnight, in this classic old ex-ski hut, which has been marked for destruction by DoC. Warm clothing and footwear for wet, windy conditions are advisable whatever the weather forecast. High wheel base 4WD advisable for those not walking. Some seats may be available. Contact Robyn Bridges, 479 8244 (day) if you wish to stay overnight (numbers limited).
