Taxonomic Comments
This record is for the narrow treatment of Hypericum perforatum as recognized in Kartesz (1994). FNA (vol. 6, 2015) recognizes four subspecies, where only Hypericum perforatum ssp. perforatum occurs in North America. Kartesz's (1994) narrow concept of H. perforatum is equivalent to FNA's H. perforatum ssp. perforatum.
