- Comments
- An extremely narrow-leaved form of this species that grows on cliffs, barrens, and rocky woodland slopes is nearly identical to Boechera burkii, except for its inconspicuous leaf-base auricles.
Eastern U.S. species of Boechera were transferred to the genus Borodinia in Syst. Bot. 38:192-209 (2013) based on a relatively close relationship with Asian Borodinia macrophylla. While w. N. American Boechera form a convincing clade, we feel that recognition of Borodinia should await additional investigation. 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
- Dry woodlands, barrens, and outcrops on a wide variety of rocks; also in rocky or calcareous soils of mesic to dry upland forests; rarely in bottomlands. Common in the mountains and Piedmont; infrequent to rare in the Coastal Plain.
