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.
