One of the rarest orchids in the United States, Platanthera chapmanii is believed to be descended from natural hybrids of Platanthera cristata and Platanthera ciliaris owing to the fact that it appears to be intermediate in form and size between these two species. Because of this, it has been given the hybrid designation Platanthera x chapmanii in some publications. While it does often inhabit the same areas where one or both of the purported parents are also found, this is not always the case. Further, it appears to maintain stable populations, sometimes rather expansive, in areas where it is found. Because of these qualities, it has been elevated in recent years to a species in its own right.
