Orchids of Australia

Australia is home to about 1,800 species of mostly terrestrial orchids. The south-east and south-west of the continent are particularly rich in species, with approximately 400 known orchid species occurring in south-western Australia alone. On this page I present some of the more common species of terrestrial orchids found throughout the temperate regions of Australia. Most of the described species are endemic to Western Australia, but a few species from the south-east of the country are included as well.

Several of Australia’s orchid species look very similar and require an expert to tell apart. This is particularly the case with Spider Orchids (Caladenia), Donkey Orchids (Diuris), Mignonette Orchids (Microtis) and Greenhood Orchids (Pterostylis). The situation is complicated further by the large number of hybrids known to exist in the wild, in particular among the Spider Orchids. Hence, a few of the species below have been marked as “unidentified”.

Lastly, most of the orchid profiles below are still incomplete and only contain photos at this stage, but no descriptions. I’m not sure if I will ever find the time to complete them.
