Changes to botanical names are a routine consequence of research into any plant group. In the last decade various genera of Australian orchids have been subject to detailed research by workers on both sides of the continent. Recent research in Canberra has included molecular studies which for the first time provide important information on the ancestral relationships of genera. As a result of these studies Australian Orchidaceae has undergone significant taxonomic and nomenclatural changes at both generic and specific rank. The generic treatment of Mark Clements and David Jones in Canberra is used as a basis for this key. This treatment is not universally accepted and a simple cross-reference list is included here to facilitate understanding of the recent changes to species names.
If you want further details on synonomy see the Australian Orchid Name Index.
