Western Australian Orchid Key

Key to the Native Orchids of Western Australia is an interactive identification and information package that will help you identify and learn about all the currently known native orchids found in Western Australia (including named hybrids).

It is designed for flowering plants and works best when they are fresh and observed in the field. It can also be used to identify orchids from Herbarium specimens but may not work as well as it does with fresh specimens in the field. The key is not designed to work with vegetative plants.

The species distributions in the Fact Sheets and in the illustrative maps are based on Herbarium collections and the personal knowledge of the authors, whereas in the interactive identification section of the Key the distributions are based on the Shires where the species could potentially occur.

Key to the Native Orchids of Western Australia has been sponsored by the Western Australian Native Orchid Study and Conservation Group (WANOSCG) and developed by its members.

The key is designed as an aid to identifying Western Australian native orchids. However, WANOSCG and the authors take no responsibility for the accuracy of results. The key does not replace the advice of professionals in plant identification and the user is solely responsible for the scientific interpretation or any regulatory decision derived from information provided in this tool.

Aims

The key is aimed at both amateur orchid enthusiasts and professional researchers alike. You can use it to:
- identify an orchid species;
- find out what orchids occur in different areas (by Shire) or habitats;
- find out which orchids flower in different months of the year;
- find out which orchids are listed as Threatened or Priority species;
- view species Fact Sheets and photos of all the orchids contained in the key; and learn more about Western Australia’s unique orchids.

Sources of information

Information and data contained in the key has come from a variety of sources including the personal knowledge of the authors and others; The Western Australian Herbarium including Florabase; the scientific literature; and from the following books: The Complete Orchids of Western Australia by Andrew Brown (2022) and A Complete Guide to Native Orchids of Australia by David L. Jones (2020) who approved the use of his authoritative and extensive source of information on Australian native o
