Yellow Lady's-slipper / Cypripedium parviflorum

Photographed at The Nature Conservancy, near Rimbey, Alberta, on June 26th, when we were on a botanizing trip to Spirit Rocks Sanctuary. This is a forest north of the city, that is under The Nature Conservancy of Canada and belongs to Joanne Susut. Joanne inherited this land, which she has named Spirit Rocks Sanctuary, from her parents and has donated it to the Nature Conservancy of Canada. It was about two and a half hours' drive north of Calgary, to near Rimbey. The day started off with rain and ended with rain, but luckily not a drop fell while we were walking. I don't have the exact location to add to my map, so have just marked Rimbey, Alberta.

There are two varieties of this orchid: Small Yellow Lady's Slipper (Cypripedium parviflorum) and Large Yellow Lady's Slipper (Cypripedium pubescens var. pubescens). When you find this orchid, do not disturb it. Do not transplant it - it will likely not survive. It is a wildflower and should stay where it is, also for other people to enjoy. I think I'm correct in saying that my photo shows the Small Lady's-slipper. Thanks Papa Ellis for the confirmation!
