This species has as yet only been found in the northern, western and south-
western parts of Iceland, see fig. 16. In N.W. it seems rather common ; in the other
parts where it is found it occurs here and there. The var. pungens Desv. (var.
alpestre Hartm.), with shorter and more rigid, pointed, erect or appressed leaves, is
more common in Iceland than the typical form.
