This looks like the mythical D. chryseopsis of Mt Majura. Although I can't quite tell if this is actually a hybrid with D. pardina. @DerekC , thoughts?
I think these are hybrids looking at the size of the labellum sidelobes. I think these are the same plants as record Diuris sp. (hybrid) (Hybrid Donkey Orchid) which I had decided were hybrids.
