Discussion | The name Sabatia paniculata (Michaux) Pursh was misapplied to this species for many years but is typified by a specimen of S. difformis (R. L. Wilbur 1955). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
There are historical records of Sabatia dodecandra from Connecticut and New York. Reports from west of the range given here have been based on a concept of the species that included S. foliosa. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
