Discussion | Polygala ramosa has been reported from Maryland (M. L. Brown and R. G. Brown 1984, as cited in the USDA Plants database); no vouchers are known. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The protologue description of Polygala setacea with “in Carolina septentrionali” is the likely source of later reports of the species occurring in the Carolinas, (for example, J. K. Small 1933; R. W. Long and O. Lakela 1971; R. K. Godfrey and J. W. Wooten 1981). There are no known specimens from either of the Carolinas; the locality reported by Michaux may be erroneous. Small reported Polygala setacea also from Mississippi; no supporting specimens are known. The presence of this species in Mississippi or either of the Carolinas would represent a disjunction from the range documented by known vouchers.
