Discussion

A station in Barbour County, West Virginia, is 240 km north of other stations and may be a result of introduction (K. B. Gregg 1989).

Cleistes bifaria has been treated as a variety of the following species; it is readily separated by its relatively short column, which is correlated with the relatively small size of other floral parts, and differences in lip keel. It is, to a large extent, isolated from the following taxon by geographic distribution and flowering time where their distributions overlap (P. M. Catling and K. B. Gregg 1992).
