Liparis loeselii, the Fen Orchis or Loesel's Twayblade, is rather widespread in range. It is found both in Europe and in North America and is reported to be common in the eastern areas of the United States and Canada. It is rare, however, in the west, having been recently found for the first time in Alberta, where these photos were taken, and with no known locations in Washington, though it has been reported from the state.
It is a small species, not taller than 20 cm and often much shorter with two leaves at the base of the plant and a dozen or fewer flowers about 1 cm in size. The flowers are pale yellowish-green and grow among sedges and other wetland plants which makes them even more difficult to find. These were photographed growing in full sun in a very wet fen and were scattered individually over a fairly large area but only in one location in the fen which was very large.
