With the exception of the retuse tepals, the characteristics by which C. L. Hitchcock (1944) distinguished subsp. absona from the other subspecies that he recognized under Tofieldia glutinosa are commonly found in subsp. brevistyla, and the former is treated here as a disjunct Idaho population of the latter.
