Description
 |
This is a biennial herb which has a small, inconspicuous basal rosette of leaves measuring a few centimeters wide. It bolts with an erect, branching stem that can reach a maximum height near one meter. Leaves along the stem may be 5 to 15 centimeters long, lance-shaped, and sometimes toothed along the edges. Leaves wither early, and the plant may have few or no leaves at flowering. The inflorescence is a raceme of several tiny white flowers each under a centimeter wide. The fruit is a silique measuring 4 to 8 centimeters in length and containing many small seeds.
Habitat
This endangered plant grows in mid-Appalachian shale barrens, an eroding shale scree of Devonian origin.[5] This habitat occurs in Virginia pine woodlands and is made up of unstable rock and thin soils which are largely weathered fragments of shale known as channery.[5] Most populations of the plant have a few individuals.[1] The rocky soils receive direct sunlight that makes them too hot (up to 63 °C) to support many plant species.[1]
Endangered status
The plant was listed as a federally endangered species in 1989.[3] In Virginia, it was given an S1 ranking ("Critically Imperiled") in 1991,[citation needed] and it is currently listed as S2, "imperiled", in both Virginia and West Virginia by NatureServe.[1]
