Discussion

Gentiana autumnalis is believed to have been extir­pated long ago from Delaware and Maryland.

Variation in the number of floral parts, from four to seven per whorl, is more frequent in Gentiana autumnalis than in the other species of Gentiana in the flora area.

There is a record of a hybrid of Gentiana autumnalis with the highly dissimilar G. villosa in North Carolina.
