This is the critically endangered Thelymitra atronitida :)

@Eamonn I am unfamiliar with T. atronitida. May I ask what features you are using to distinguish this from T. alpina?

Hey, T. atronitida has a shiny black PAL, with a strong transition to the short, yellow tip, that is notched in a different way to the T. nuda group.
Compare with these photos

Hi Eamonn, respectfully disagree here. Flowers were large, column arms weren't curved upwards and post-anther lobe wasn't notched in the way it appears in those T atronitida photos.

Yep, I think I was too hasty, it just has such a strong contrast in the PAL.
T. atronitida usually has strong lines on the sepals too

I welcome the discussion. Thelymitra are very difficult to ID so any comments are greatly appreciated.
