Other info. - This orchid was originally brought to the U.S. as a medicinal plant. It has since escaped and can be found scattered throughout the eastern half of the U.S. The plant is rare in Missouri but will probably become more frequent as the state has ideal habitat for the plant. It was originally collected in this state in 1928 and again in 1938.
A synonym is E. latifolia (L.) All.
