Some of my talks

Houlletia tigrinaI first started speaking to orchid societies in the days when there were just Kodachrome slides and rather unreliable projectors. I often used two projectors to contrast and compare different orchids. The advent of digital projectors, PowerPoint and digital cameras has made the job easier for me, although not necessarily for my partner, Roger, who does all the technical computer work!

Houlletia tigrinaOver 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 to give a context for the talk.

Houlletia tigrinaThere are a number of different subjects on which I have given talks and I am constantly adding to them, both about different places I have been and as a result of specific requests from orchid societies. Most talks last about 45 minutes, depending on the questions and discussions which they generate.

Houlletia tigrinaListed below are some of the talks which I have already given and can repeat or vary if requested. Bear in mind that I live in Brisbane, Australia, so may like some help with travelling costs if you are not in this area.

Orchid genera

Houlletia tigrina 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.
