Cypripedium acaule
Cypripedium acaule is very widespread from north to south in the eastern Unite States. It occurs in a variety of habitats that vary from bogs to dry upland pine forests. The common aspect among these habitats is the very acidic pH of the medium. The flowers of Cyp. acuale are usually pink but vary to white and very dark cherry-colored flowers. We have listed several of the varieties that have been described, consistent with Cribb.
- C. acaule Aiton 1789
- forma albiflorum Rand & Redfield 1894
- forma biflorum PM Brown 1995
