Discussion
Typical var. rugosa is a generally more northern race of the species but occurs infrequently scattered across the southern United States. Although var. villosa has often been recognized (e.g., H. A. Gleason and A. Cronquist 1991), it grades completely into var. rugosa. Single clones include shoots with long-branched arrays and others with short-branched ones not exceeding the subtending leaves. The variety is diploid throughout its range, with a few scattered tetraploids.
Subspecies 2 (2 in the flora): e United States; Mexico.
