Four Orchids in Sherman Pass

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, 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.

Another location I visited on May 20th, but much further north, was a site where the Eastern Fairy Slipper, Calypso bulbosa var. americana, grows in abundance, but I found it near the end of its bloom season and early like everything else.  This variety of the Fairy Slipper is very different from the Western Fairy Slipper, with a yellow beard on an otherwise nearly unspotted lip.  Nor does it grow west of the Cascades as does the Western Fairy Slipper.  I also found in the same location one plant still in bloom of Kostiuk's Hybrid Fairy Slipper, Calypso bulbosa x kostiukiae, a rare natural hybrid of the Eastern and Western Fairy Slippers.  It is also very distinctive, with a pale yellow beard, midway between the bright yellow and white of the two varieties and a finely spotted lip.  With these two Fairy Slippers there were also several stems of the Early Coralroot, Corallorhiza trifida.
