Varieties 2+ (1 in the flora).
Gentiana prostrata is variously divided into subspecies and/or varieties. At least two, perhaps more, varieties seem appropriately recognized at that rank (one in the flora).

Gentiana villosa is believed to be extirpated from Delaware, the District of Columbia, and New Jersey.
Although the name Gentiana ochroleuca is a heterotypic synonym of G. villosa, it was sometimes applied to G. flavida during the nineteenth century. Such a misapplication is responsible for reports of G. ochroleuca from Illinois. Reports of G. villosa from Arkansas are plausible but remain unsubstantiated.
The species name is a misnomer as plants of Gentiana villosa species are glabrous. The use of the translation “hairy gentian” as a common name is inappropriate and potentially confusing.
There is one record each of hybrids of Gentiana villosa with G. autumnalis and G. catesbaei.
