Discussion
Listera ovata is a large, robust, aggressive, and exceedingly common orchid weed found in many kinds of habitat throughout Europe into Siberia and India. It may have the potential to become a weedy orchid in North America just as Epipactis helleborine. Listera ovata was used by Charles Darwin in his investigation and description of the method of cross-fertilization in the genus Listera.
