Discussion | Sabatia capitata is endemic to the southernmost portions of the Cumberland Plateau and the Ridge and Valley Province in northern and central Alabama, northwestern Georgia, and southeastern Tennessee. An old specimen was labeled by a later recipient as being from North Carolina, but its provenance is uncertain. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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).
