Distribution
B.C., Man., N.W.T., Que., Yukon, Alaska, Europe.
Discussion
I. A. Worley and Z. Iwatsuki (1970) recorded var. orthophyllum from Alaska. It is an extremely weak Arctic variety that differs from var. majus in only a few minor characters. The plants immediately appear different because of the erect-patent, short leaves instead of the long, falcate-secund leaves of var. majus. More collections are needed from many Arctic localities to better understand var. orthophyllum, which may only be an environmental form.
