• Like other " Frasera ", it was previously included in genus " Swertia ", and some authors will retain it in that genus.
• The roots of " F . caroliniensis " are a taproot system, with a thick and fleshy taproot, and in some " Frasera " species, this may be modified into a branched rhizome.
• Historically, " Frasera " has sometimes been considered part of " Swertia ", but molecular analysis of a number of " Frasera " species has shown them to form a monophyletic clade separate from the rest of " Swertia ".
