Borodinia laevigata is a species of flowering plant in the mustard family known by the common name smooth rockcress.[1] It is native to many areas of the eastern United States and Canada, where it grows in calcareous rocky woods and bluffs.[2] It is moderately common throughout its range, although it is absent from the southeastern coastal plain and the far north.
This species is a biennial herb growing from a single stem. It flowers in early spring and has persistent fruit. It is differentiated from other species by its auriculate-clasping leaves, short white petals, and glaucous stem.
This species was moved to the genus Borodinia in 2013 following a genetic analysis.[3]
