We did some orchid hunting and hiking recently in eastern Washington and in two different areas had opportunity to see a lot of the Spotted Coralroot, Corallorhiza maculata var. maculata, and its variety, the Western Spotted Coralroot, Corallorhiza maculata var. occidentalis. These two are well defined varieties in that where they grow in the same location they have different blooming seasons, the Western Spotted Coralroot, the subject of this post, blooming several weeks earlier than the other variety. The difficulty is that at higher elevations and as the season progresses they seem to bloom concurrently and then it is very difficult to tell them apart. Flower form does differ somewhat in that the Spotted Coralroot has a straight-sided lip while the Western Spotted has a rounded mid-lobe, but flower form is variable even on a single plant and this alone is not sufficient to distinguish the two varieties, in my opinion. I am including the plants shown below, photographed later in the season, under var. occidentalis on account of their flower form.
