The text comes from "Meet the Ladies" - a page at the US Forest Service website devoted to the "slipper orchids." We have three varieties in Minnesota. At the top and below are examples of the Showy lady's slipper - the state flower for Minnesota.The genus name Cypripedium is derived from the Greek words "Cypris," an early reference in Greek myth to Aphrodite, and “pedilon” for sandal. This is because the fused petals that form the orchid’s pouch or modified lip (labellum) resemble a slipper or shoe. The staminode (sterile stamen) is often showy and seems to welcome the insect into the pouch where it makes its way to a back-door exit and in so doing transfers pollen to the stigma.
White lady's slipper, which is more of a prairie flower, but the Yellow lady's slipper is fairly common.
