Discussion

It is assumed that after the maximum glaciation, recolonization of most glaciated areas by subsp. glauca spread from the Alaska-Yukon refugium eastward to Hudson Bay, Newfoundland, and the New England states and, perhaps from a putative Rocky Mountains refuge northward to the Yukon and eastward to the Great Lakes area (G. Staudt 1999).
