Today’s photograph is shared by Ron Long, again from his recent trip to Western Australia. Thanks Ron!
When Ron sent along the photograph, he added the following: “There has been a great deal of imagination applied to choosing common names for many Australian orchids. This one is called Cossack dancer and having learned that I can’t help but laugh every time look at this picture.”
While the common name is plenty descriptive and stable, the scientific name for this orchid has been rather fluid recently. It seems like it has settled on Jonesiopsis dorrienii, but other publications / people continue to use Caladenia dorrienii (or here and here) or Calonema dorrienii. Whatever its name, it is listed as endangered in Western Australia (where it is endemic). The morphological diversity of this group of orchids can be viewed on this page, just bear in mind that the names may not be current.
I should also point out that the flower of this species is (classically, for orchids) resupinate, in contrast to the flower of Cryptostylis erecta
