What is the Shadow Witch Orchid's range?

East of the Mississippi River is the range of the Shadow Witch (Ponthieva racemosa).

Specifically, the wild orchid ranges as far north in its southeasterly extension as Virginia. It may be found growing as far southeasterly as Florida. It is found growing all along the coastal plain between the two states. It also grows southwestward from Florida, across the Mississippi River and into Texas.
