Day 196: One of the most exciting moments in a naturalist's career is the discovery of a species they have not observed before. Following a report from a former Park volunteer, I made a total of four trips trying to locate and obtain a decent photograph a solitary specimen of unusual orchid, and even once I had it "in the bag," I was baffled. Since I could not identify it myself, I sent the photo out to several experts in native plants, and just before bedtime last night, I received an identification from one of them: Corallorhiza trifida, aka Early or Yellow Coralroot.
According to Susan McDougall and David Biek, C. trifida is "rare at Mount Rainier....circumboreal, but is uncommon here in the northwest and recorded a couple of times apparently at the mountain...A terrific find!" It is so unusual that they want to photograph it themselves before the blossoms fade. During a plant survey in the Park last year, they had been unable to find an occurrence of the plant.
Even more exciting for me, of course, is the fact that this rare Corallorhiza is also a partial mycoheterotroph, a group of plants in which I have a particular interest. I believe our mild winter may have allowed the mycorrhizal components of many mycoheterotrophic species to proliferate, thus bringing to the surface a greater number and variety of plants than we'd see in a normal year.
Dear little Corallorhiza trifida, if you were a bird, you'd go on my Life List, but unfortunately, I haven't kept good records of my botanical finds. Maybe you've given me reason to start!
