Summery. The leaf narrow (5mm), possibly channelled and rib. Back of sepals distinctly pinky-red and white. Column blue-purple with little or no post-anther dark colouration just a dark yellow apex, not hooded or grooved with an inverted "V" opening. Column arms straight with white mop-shaped hair-tufts. Stem erect straight and redish with 7-8 flowers and using Paul's thumb as a guide about 30mm across. As it was raining at the time it is hard to know its opening propensity. It should be easy.
After looking at my photos of this plant I should add the upper surface of the post anther lobe is not smooth but rather has a number of small pimple like bumps.
I have now added at Thelymitra (genus) (sun orchids) several photos from my records of this same plant showing the post-anther lobe detail indicated above.
