Discussion
Variety septentrionalis was first described by Fernald, who found it occupying a number of unique boreal and subalpine areas of the northeastern United States and southeastern Canada; it was raised to specific rank by Á. Löve and D. Löve based upon its chromosome number (2n = 54). Populations of var. latifolia that have been ascribed to var. septentrionalis are cited as differing in being alpine, subalpine, and boreal. In New Hampshire, D. D. Sperduto (2005) characterized it as an alpine and subalpine obligate that occurs in ravines and snowbed communities. A. Haines (pers. comm.) could not find any unique floral morphological characteristic to distinguish populations of var. septentrionalis from var. latifolia. Additional work is needed to determine if the polyploid populations (identified as var. septentrionalis) have unique ecological tolerances and if other physiological or morphological characteristics will allow consistent distinction from var. latifolia.
