cypripedium ID?

[pontus]

Could someone please help me ID this highly scented green and yellow cypripedium which appeared as a nice surprise in a pot of cypripedium calceolus?

thank you

you may be very lucky and have the flavum form of cyp calceolus!
I don't know any true alba green cyps that look like that.

that would be amazing!

the closest I got myself in guessing was cordigerum, but I grow cordigerum, which flowers in late june/early july here, and has a white lip with green petals, and not a yellow green lip... but cordigerum is also highly scented..

I'm by no means a Cyp expert, but I was thinking henryi at first.. 
 calceolus var flavum  does seem more likely

I think the shape of the flower isn't quite right.
