So why do you have a photo of this same flower as two different species? Cypripedium has a parent page for all that are not properly ID. As I look further into your dilemma it seems there is much confusion about these and others that even the experts disagree about. Good luck with this. I love the all the Slipper Orchids. Yours is quite a beauty.
