Notes: FNA8: "Plants in open, alpine and arctic habitats often have leaf blades orbiculate to orbiculate-ovate, 10-20 mm, apices obtuse, anthers ca. 1 mm, and styles 3-4.5 mm, and have been called Orthilia secunda subsp. obtusata. E. Haber (1972) concluded that these characters vary too freely among populations to warrant distinction."
