Pink lady's slipper (Cypripedium acaule)

Description

Unlike most other species of Cypripedium, the pouch of C. acaule opens in a slit that runs down the front of the labellum rather than a round opening. The plant consists of two plicate leaves near the ground. From between those leaves sprouts a long, pubescent stalk that bears a single pink flower. The sepals and petals tend to be yellowish-brown to maroon with a large pouch that is usually some shade of pink but can be nearly magenta. The white pouched-green petaled forma alba can occasionally be found mixed in with normal populations.
