Taxonomic Comments
This record is for the narrow treatment of Gentianella amarella as recognized by Pringle in FNA (2023, vol. 14) which excludes G. heterosepala and G. wrightii as distinct species. Kartesz (1994) recognized both as subspecies of G. amarella, while Kartesz (1999) accepted G. wrightii as distinct, but included ssp. heterosepala. The only subspecies of G. amarella (in this narrow sense) reported for North America is ssp. acuta.
