Discussion

Subspecies pallida is an eastern woodland-prairie relict (W. A. Weber 1990), occurring in the Black Hills of South Dakota and adjacent Wyoming, the eastern foothills of the Colorado Front Range, and in a few scattered locations southeast to the New Mexico–Oklahoma border area. It is usually much shorter (20–80 cm) than is typical for the species, the array representing about half the height of the shoot. The leaves are much less crowded than those of var. rigidiuscula. A few plants similar in appearance to subsp. pallida, but taller, have been seen in the Carolinas and Tennessee; they belong in var. speciosa.
