Discussion

Absence of consistent diagnostic criteria appears to prohibit the complete distinction of var. muriei from var. australis of the southern Europe type locality for the species. Petiolate specimens occur throughout the range of var. muriei, with distal leaves less often sessile. The type of this variety has strigulose fruits, which are unusual in plants from the arctic but not of diagnostic value within the group.
