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.) |
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.) |
