Braun’s rock-cress, Arabis perstellata, a perennial member of the mustard family (Brassicaceae or Cruciferae), is comprised of small rock cress and large rock cress subspecies that occupy distinct geographic areas in Kentucky and Tennessee, respectively. E. L. Braun described this taxon in 1940 from plants collected on wooded hillsides along Elkhorn Creek in Franklin County, Kentucky, distinguishing it from similar species in the area. Current taxonomy recognizes his distinction between A. shortii and A. …

ITIS Reports — ITIS (the Integrated Taxonomic Information System) is a source for authoritative taxonomic information on plants, animals, fungi, and microbes of North America and the world. This rockcress is a perennial herb with decumbent stems reaching 80 centimeters in length. The stems spread out horizontally, and often droop over the side of any structure the plant may be growing on, such as a rock or cliffside. The leaves are arranged in a basal rosette with some alternately arranged along the stem. The stems and leaves are gray-green in color due to a coating of whitish star-shaped hairs. The inflorescence is a raceme of flowers with four white or lavender petals each a few millimeters long. The fruit is a hairy silique 1.5 to 2 centimeters in length which contains tiny reddish seeds.
