Platanthera x estesii

This is almost certainly Estes Rein Orchis, Platanthera x estesii, a natural hybrid of Platanthera dilatata and Platanthera stricta, photographed along the Yellowhead Highway in Mount Robson Provincial Park, British Columbia, on a recent trip to Edmonton to see family. This plant was growing in every wet, boggy area along the highway, and though common is nevertheless beautiful with its masses of greenish-white flowers.
