Traveling to eastern Washington, I did some hiking in the area of Sherman Pass in Colville National Forest. I was looking for the Northern Twayblade, Listera (Neottia) borealis, a plant I had seen many times in the Canadian Rockies and never here in Washington. Using GPS coordinates given me by a friend, I found it at the peak of its bloom right along the trail, about a dozen plants and growing with it, the Early Coralroot, Corallorhiza trifida, though that was very nearly finished blooming. Later, continuing my trip, I stopped along the road to photograph a large colony of the Stream Orchid, Epipactis gigantea, and some Sierra Rein Orchis, Platanthera dilatata var. leucostachys, growing with them. The star of the show, though, was the Listera, a first for me in Washington.
