Neottia borealis (syn. Listera borealis), the northern twayblade,[3] is a species of terrestrial orchid found in North America. It is widespread across much of Canada, including the three Arctic territories, and also occurs in the mountains of the western United States from Alaska to northern New Mexico.[2][4][5]
Taxonomy
Neottia borealis was scientifically described in 1893 by Thomas Morong who named it Listera borealis. It was moved to the genus Ophrys in 1905 by Per Axel Rydberg and finally to Neottia in 1995 by Dariusz Szlachetko. It has no accepted subspecies.[2]
