Cypripedium parviflorum

We left the conference on Friday afternoon and headed out to a wonderful protected site called Wagner Natural Area. It's open to the public, but many just go there for the hike through the woods.

I've never seen so many orchids in one place. Some of these may actually be the variety called "makasin", but there is so much variability at this location, that these may all just be color forms of the same species.
