The Spider Orchids are the largest genus of orchids in Western Australia. There are around 180 species in Caladenia<\/em> with about 140 found in the south west of Western Australia. There is huge variation in size, colour and shape. Size ranges from the tiny Winter Spider Orchid (1-2cm) to the huge Giant Spider Orchid (up to 30cm).
\nThe species on this page are divided into four groups. Within these groups, species are arranged into smaller groups based on flower similarity. Click on the thumbnails to view enter the groups, and then to view the photos.<\/p>\n

Group 1 - The Big Spider Orchids<\/h2>\n

This group contains all the species that have long fringing on the labellum. I have called the group 'Big Spider Orchids' as most of them have large, showy flowers. There are, however, some very small species in this group.<\/p>\n

Group 2 - The Wispy Spider Orchids<\/h2>\n

The characteristic feature of these species are the thin, wispy petals and sepals and a labellum with very short (if any) fringes. Some years ago, the name Caladenia filamentosa<\/em> was applied to all the wispy spider orchids. As there were many variations, many of which formed stable populations, the species has been divided into many separate species, some of which are very similar in appearance. This makes identification quite difficult. Differences include flower size, flowering time, range of distribution, size of the labellum and colour. However, many species show large variations in colour and size anyway, which further complicates identification. Therefore, there is a good chance that some of the species listed here are not identified correctly. Those I am not totally sure about are marked with an asterisk (*). Most orchid enthusiests will refer to the Wispy Spider Orchids collectively as 'filimentosas<\/em>'<\/p>\n
