P. Stoutamire 1978).It can be found in every county of Georgia, but in some states such as Pennsylvania, Florida, and Massachusetts it is considered threatened.

Cultural Information

This species of orchid has no medicinal or cultural significance.

The name orchid is from the Greek word "orkhis", which means testicle. Because of this translation, the orchid symbolizes sexuality in many cultures. To determine if a man was going to have a boy or girl in ancient Greece, they (men) would eat large root tubers for a boy and smaller ones for a girl.
