Victoria has a wonderful, varied orchid flora of 363 species making it one of the richest areas in the world for terrestrial orchids. They can be found from sea level to the highest mountains, from swamps to deserts. The flowers occur in a fascinating array of forms from just a few millimetres across in the onion orchids to almost 200 millimetres across in the spider orchids. 1490 photographs detail all of the orchids in Victoria. Each species has a descriptive text, which along with the photograph should enable the user to identify orchids found growing in the wild.
