Notes

The Slender Sun Orchid is endemic to south-western Australia, where it occurs south-west of a line from Geraldton to Esperance. While superficially similar to other blue Sun Orchids, it is readily distinguished by its tiny flowers, the fact that the sepals and petals have slightly different shades of blue, and the stalks supporting the white column tufts, which exhibit a characteristic 90° bend.

The peak flowering period of the Slender Sun Orchid is spring. The orchids grow in a wide variety of different soils and seasonally wet habitats, including winter-wet flats, the edges of swamps and along creek lines. In the far south they can also be found in coastal heath in close proximity to the ocean.
