Notes: Elven and Yurtsev: The northern plants have been considered a subsp. nana (Khokhrjakov and Mazurenko 1991). It is uncertain whether they represent a morphologically and genetically separable race or the northern parts of a cline. We have seen no convincing differences among northern European, Siberian, Alaskan, and eastern Canadian plants and favour the latter hypothesis.
