|---|---|---|---|---|---|
| Brassicaceae | Borodinia burkii | Burk's Smooth Rockcress | Limestone barrens, shale barrens, and other dry, rocky habitats. | E. and c. PA south to e. WV, ne. TN, and w. NC in the sedimentary rock Appalachians. Radford, Ahles, & Bell (1968) attributed this plant (as Arabis laevigata var. burkii) to NC based on somewhat aberrant specimens from high elevation cove forests; these are better assigned to B. laevigata. Hopkins (1937), however, cites a specimen from Hot Springs, Madison County, NC, an area with plausible habitats (dry sedimentary rock woodlands, shale barrens). |  |
| Brassicaceae | Borodinia canadensis | Sicklepod, Canada Rockcress | Thin soils around rock outcrops, especially mafic or calcareous, and in dry to mesic, nutrient-rich, often rocky woodlands over mafic or calcareous rocks. | QC and ND south to Panhandle FL and TX. |  |
| Brassicaceae | Borodinia dentata | Nutrient-rich alluvial and river bluff forests. | NY west to MN and SD, south to n. VA (along the Potomac River), nc. TN (Chester, Wofford, & Kral 1997), and AR. |  | |
| Brassicaceae | Borodinia laevigata | Common Smooth Rockcress | Rocky woodlands and forests, rock outcrops, especially mafic or calcareous, but also on more acidic substrates, rarely also in bottomlands. | ME west to MN and SD, south to GA, AL, MS, AR, OK, and CO. |  |
| Brassicaceae | Borodinia missouriensis | Missouri Rockcress | Thin soil around outcrops of metamudstone, diabase, or granite (generally on ultramafic, mafic, or 'rich granitic' substrates). | ME to WI, south to KY, AR, and OK; disjunct eastward in NC, SC, and GA. The distribution of this species is odd and fragmented. |  |
| Brassicaceae | Borodinia perstellata | Calcareous bluffs. | Apparently endemic to KY and c. TN (Chester, Wofford, & Kral 1997). |  | |
| Brassicaceae | Borodinia serotina | Shale Barren Rockcress | Shale barrens. | Endemic to Devonian and Ordovician shales of w. VA and e. WV. |  |
