Its hard to say.
A nice one anyway.
could be a parviflorum kind hybrid, A fasciolatum Hybrid I dont think so.
Waht is the size of the flower.
Ventricosum ????????? Which form should take part on that
Agreeing with this. I don't see a bit of fasciolatum in it. Remember, Cypripedium parviflorum var. pubescens is extraordinarily variable, perhaps being rivaled by only Cypripedium flavum in amount of flower variation.
