Cypripedium acaule
Unlike most other members 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.
C. acaule can be found in the eastern third of the United States and north into Canada, coming very close to the Arctic circle. This widespread species can be found in a wide variety of environments, from coastal plains, to pine barrens, to mountaintops.
Found while hiking along the AT. May have been over 50 plants in this one small area.
