Comments
"The shale barren endemic, Arabis serotina (Brassicaceae)," published in Sida 12(2):381-389 (1987) resurrected this species from the synonymy of Arabis laevigata var. burkii (= Boechera burkii). It is a true shale barren endemic known only from the more central portion of the shale barren region in Virginia and West Virginia. Listed as federally endangered by the U.S. Fish and Wildlife Service. There is an additional sight record from Page County (J.C. Ludwig, pers. comm.) that has not been vouchered. Ironically, this site probably has the largest known population of the species.

Eastern U.S. species of Boechera were transferred to the genus Borodinia by Alexander et al. (2013, Syst. Bot. 38:192-209) based on a relatively close relationship with Asian Borodinia macrophylla. While w. N. American Boechera form a convincing clade, we feel that additional studies are needed to firm up support for the transfer. Inclusion of only a single Asian species and stair-step relationships between a number of genera may belie the best placement of our eastern taxa.
Habitat
