Discussion | 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.) |
Reports of Sabatia brevifolia from Louisiana were based on a specimen of questionable provenance and are considered probably erroneous by students of that state’s flora. In some older literature, the name Sabatia difformis was misapplied to S. brevifolia. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
