This orchid is tiny, growing up to 10cm tall with flowers from 2-4cm long. The name 'sigmoidea' means S-shaped and refers to the labellum, the tip of which bends forward, rather than curling underneath, as in most other spider orchids. The orchid is found mainly in a triangular area bounded by Mt Jackson, Hyden and Israelite Bay. It's favoured habitat is leaf litter under salmon gums in dry, barren-looking country, often in association with the Midget Greenhood (Pterostylis mutica). It is also found growing in leaf litter under mallee shrubland.

Caladenia x tryphera - Delicate Spider Orchid
This orchid is a hybrid between the Sigmoid Spider Orchid, Caladenia sigmoidea, and the Western Wispy Spider Orchid, Caladenia microchila. It is reasonably common in areas where both parent species are found. It is identified by the petals and sepals that often have streaks of red and the labellum , which is partially recurved like the Sigmoid Spider Orchid parent.
