It's funny this thread was started 11 days ago but nobody responsed. Anyway, now I am the first one.
It's a lovely flower, no doubt.....as to your question, you can see signs of P. sukhakulii in this flower (if you want to see them) e.g. the shape of the dorsal....but you can't see them clearly....so all is possible. It seems to be a first timer flowering plant, so I would wait for the next flower .......
