Discussion
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.
