Notes: Fries' var. borealis is characterized by subglabrous, yellowish green leaves without bloom on the lower surface, and mostly glabrous capsules. This is a northeastern lowland plant in Fennoscandia. Another morph occurs in the mountains and in the northern and northwestern lowlands, with hairy, dark green leaves without or with some lower surface bloom, and most often with hairy capsules. This second morph is the one introduced and spreading in Iceland. It is not at all clear that the two morphs should be merged into one race.
