Plants from Fennoscandia are generally smaller than those from Svalbard and have narrower panicles. They have been described as var. algidiformis (H. Sm.) Holmberg. In Russia this name has been applied to similar plants intermediate between 1 and 2, of supposed hybrid origin and occurring with the putative parents. The status of such plants requires investigation as do also the occasional reports of sterile hybrids between 1 and 2.
