It's a "circumpolar alpine" plant. Only one species, D. Lapponica, is recognized worldwide. It's interesting that most of the flowers in your photo are on branched stems, which I've not noticed in this species before.
"After the first glass, you see things as you wish they were. After the second, you see things as they are not. Finally, you see things as they really are, which is the most horrible thing in the world."
