Discussion | A historical record of Sabatia difformis from Maryland is documented, but no recent collections or reports are known from that state. Old reports of S. lanceolata from New York and Tennessee, for which no documentation was found in studies for this flora, are believed to be erroneous, probably based on misidentifications or misapplications of the name. The name Sabatia paniculata (Michaux) Pursh is typified by a specimen of S. difformis but has often been misapplied to S. quadrangula (R. L. Wilbur 1955).
