Yellow lady’s slipper orchid, near Cochrane, Alberta. Photographed 27 June 2014.
I’m still trying to work out the specific epithet on this beauty: it appears that older literature lists it as Cypripedium calceolus (Eurasian yellow lady’s slipper), but there seems to be a more recent gravitation towards different names for the North American species (of which there are more than one). I’m going to go with C. parviflorum on this, but I’d definitely welcome more information. (UPDATE, December 2017: C. parviflorum it is! Thanks to Ben Rostron for the valuable assistance regarding ID).
No matter what the name, it’s definitely a treat to come across these lovely orchids in the wild!
