Did you know?
Whitlow grass was the European name given to several inconspicuous wildflowers such as Saxifraga tridactylites, Draba verna and Paronychia which were thought to be a cure for the Whitlow. This is an infection of the end of the fingers and toes around the nail, as well as the hooves of animals, which caused painful inflammation. The genus Draba is from the Greek "drabe" meaning sharp or acrid and refers to the burning taste of the leaves of these medicinal plants. In the northeastern states Draba glabella is critically imperiled, and known only from the shorelines of large lakes in New York, Vermont, and Maine

State Ranking Justification [-]
There are only two verified and current locations, with one additional historical location recorded. There is plenty of apparently suitable habitat, and additional searching is warranted. This species is relatively inconspicuous and therefore may have been overlooked.
