Estes Hybrid Rein Orchis (Platanthera x estesii)

This plant is a natural hybrid between Platanthera dilatata var. albiflora and Platanthera stricta.  We have found it in several places where these two species grow together.

It looks more like P. dilatata than P. stricta, like a greenish-white version of the former species.  The plant and flower size are nearly the same also as for that species.
