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.

Draba arabisans may be told from its closest New York relative, Draba glabella, by its twisted fruit and longer styles.

State Ranking Justification [-]
There are only 12 verified locations, with many historical locations remaining to be checked. This species is relatively inconspicuous and may occupy inaccessible habitats, and therefore may be overlooked.
