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.) |
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.) |
