Over the years I have spoken at a number of meetings both in Australia and elsewhere on a wide variety of subjects. I use a PowerPoint presentation to which I give an individual commentary, depending on the interests of the society or group concerned. I often include some ‘tourist’ information when there has been travel associated with a conference or trip.

 

The wider acceptance of Zoom and other virtual meeting software has meant that I have given lots of talks ‘remotely’ to groups interstate and overseas.

I have talks on a number of different subjects and I am constantly adding to them. They are about places I have been, particular genera or species, or other subjects requested by orchid societies. Most talks last about 45 minutes, depending on the questions and discussions which they generate.

Listed below are some of the talks which I have already given and can repeat or modify. Bear in mind that I live in Brisbane, Australia so may like some help with travelling costs if you want me to appear in person. However, ‘virtual’ talks are much easier.

If your favourite subject isn’t here, let me know!

Orchid conferences

The 22nd World Orchid conference and show was held in Guayaquil, Ecuador in 2017 and included some spectacular species from South America as well as other parts of the world.

The 21st World Orchid conference and show was held in Johannesburg, South Africa, on 10-14 September 2014. I also travelled to Cape Town and Madagascar, where I photographed a number of orchids in the wild, as well as seeing some amazing other plants and scenery.

The 20th World Orchid conference and Show was held in Singapore, in November 2011, and I was particularly interested in the species orchids.

The 19th World Orchid Conference and Show was held in Miami, Florida, USA in 2008. Displays and prize-winning orchids, and others are featured.

The 18th World Orchid conference and show was held in Dijon, in central France in March 2005,in conjunction with the Florrissimo which takes place there every four years. I have talked separately about the show itself, the species orchids, and the Slipper orchids.

The 20th Australian Orchid Conference and Show was held in Mackay, Queensland, with theme of ‘Orchids in Paradise’. It is not often you see a brand new Holden Ute in an orchid show, and it also gave me the opportunity to find some of the native species in the area.

The 17th Australian Orchid Conference and Show, also had the theme ‘Orchids in Paradise’ and was held in Port Macquarie, in Northern New South Wales in 2006, with speakers from around the world.

Spectacular West Australia. Springtime in Western Australia is the best time to see its amazing collection of unique wildflowers, and is also the time at which they organise their orchid shows and conferences. On one trip I photographed 60 different orchid species in the wild, many of which cannot be found anywhere else in the world. WA is also host to one of the amazing underground orchids.

Trekking Northern Thailand with a local orchid expert I was able to see many of the unusual species in the mountain areas.

A taste of China and China and Thailand were trips to photograph orchids in high mountain habitats in Yunnan, and Sichuan Provinces in southern and central China, and in parts of northern Thailand. They were a mix of very isolated areas, in small villages, and tourist areas with big hotels.

Trekking Yunnan, China A trip organised by Wenqing Perner and her late husband took us to various mountainous areas Southern China, which I supplemented with a trip with another local expert.

The orchids of Madagascar are unique, as are some of the other flora and fauna. I was able to photograph some of the species, and also talk to various conservationists.

Orchids in Guatemala. Guatemala has a number of unique orchid species, as well as having others which can be found further north, and south in Central America.

Orchid Conservation in Costa Rica. The 3rd International Orchid Conservation Congress was held in San Jose, Costa Rica. The talk includes the 36th National Orchid Show, Lankester Botanic Gardens, and the Orchid Garden at Monteverde. Costa Rica is the country with the highest proportion of National Parks in the world.

Slippers in Ecuador and Peru. Yes! there are orchids at Machu Picchu as well as several other parts of the Andes, and the Amazon basin.

Exploring Ecuador and Exploring Ecuador and Peru. Yes! there are orchids at Machu Picchu, as well as several other parts of the Andes, and the Amazon basin. These talks feature species in situ, and the wonderful orchid collection of Ecuagenera in Gualaceo.

See behind the scenes at the Royal Botanic Gardens, Kew, Wisley RHS Gardens, and the National Collection of Anguloa, Ida & Lycaste in the UK, the Eric Young Orchid Foundation in Jersey, the Singapore Botanic Gardens, Kabukiran Orchids in the Philippines, Orchid Zone in the USA, Ecuagenera in Ecuador, and Kenntner’s Nursery buried in snow in Germany!

Weird and Wonderful Species. A small selection of wonderful species from the 30,000 found throughout the world. Not all of these are weird but they are certainly unique.

Orchid genera

Dendrobiums of Australasia presents Dendrobium species from the Australasian region (Australia, New Guinea and the Pacific Islands). This presentation discusses recent classification changes – or not, depending on which taxonomist you follow.

Dendrobiums of New Guinea. A range of unique Dendrobium species that are found on the world’s second largest island. Species from various sections are covered, plus taxonomic changes are also discussed.

Asian Dendrobiums. A popular genus in cultivation, there are nearly twelve hundred species, included in the genus Dendrobium. The ones from mainland Asia are confined predominantly to that continent, and are the focus of this program.

Indian Dendrobiums There is a wide variety of Dendrobiums in the Indian subcontinent, mainly spring-flowering in deciduous forests.

Cattleya Species looks at the traditional Cattleya species, plus recent additions, which have come about due to the reclassification of genera, based on recent DNA work.

Bulbophyllum and its Allies. Bulbophyllum is a huge, pantropical genus of about one thousand species. This program provides a look at some of the species from the numerous, and varied sections, which are found from Africa, Madagascar, southeast Asia, New Guinea, Australia, and the Americas.

Oncidium and its Relatives provides an overview of the Oncidiinae. Recent DNA work has suggested all sorts of confusing name changes.

Encyclia and Prosthechea looks at these two central and south American genera, which were once lumped together.

Vanda and Phalaenopsis Species summarises some of the recent reclassifications of these genera.

A Selection of Aëridinae covers a selection of vandaceous genera, which are predominantly found in the southeast Asian, and Australasian region.

What Happened to the Brazilian Laelias? Recent taxonomic changes has meant that the Brazilian Laelias are not Laelias anymore.

Paphiopedilum subgenus Brachypetalum A discussion of the origins and distribution of the species in the subgenus.

The Genus Coelogyne – an Overview A discussion of the classification and distribution of this genus.

The Pleurothallid Alliance A discussion of the origins and distribution of the species in the Alliance.

Dendrobium Is it in Danger of Extinction? Extensive use of some Dendrobium species for medicinal purposes in Southeast Asia is endangering it in the wild, but encouraging commercial production in the millions.

Other subjects

Orchid Fascination. An introductory talk for people who are not familiar with orchids; how they are identified, how and where are they grow, and how they are used throughout the world.

An Introduction to Species. What is a species, how are they named, what types of species orchids are there? Also, a discussion of the pests and diseases, and suitable environments. A list of suitable species for subtropical areas is also given, with suggestions of where they can be obtained.

Why Does My Orchid have More than One Name? One of the most common questions of hobby growers. I talk of the history of naming orchids, the difficulties of deciding which name to use, and the recent changes as a result of DNA work.

Lump or Split? With all the DNA work, various specialists are lumping some genera into a single name, while others are splitting them into individual, new, or resurrected names. Taking Australasian Dendrobium species as an example, I ask are you a lumper or a splitter?

Orchid Types. A look at different orchid genera, by going through an A to Z of generic names, which were published by John Lindley.

Miniature Species – A Selection. Where space is limited, a collection of miniature orchids does not take up much room. Some flowers may be small, but some can be very large for the plant size.
