Taxonomic Comments
Alexander et al. (2013), recognizes this taxon as a member of the genus Borodinia, distinct from Boechera. The FNA (2010, vol. 7) treatment accepted it as distinct from Arabis laevigata and in the genus Boechera. It was also recognized as distinct by Kartesz (1994, 1999) and many others. Mulligan (1995, Arabis synopsis, Rhodora 97: 109-163) treated these plants in the widespread species Arabis laevigata, without recognition of any infraspecific taxa (cf. Rollins 1993).

Rank Reasons
Although not common in most of its range, Borodinia missouriensis appears to have a stronghold in the Ozark region of Missouri and Arkansas. It also occurs north to Minnesota and east to Maine and the Atlantic coastal states in woodlands with sandy or rocky, acidic soils.
Range Extent Comments
Borodinia missouriensis is known from Maine to Minnesota, south to Maryland, Kentucky, Arkansas, and Oklahoma; disjunct eastward in North Carolina, South Carolina, and Georgia (Flora of North America Editorial Committee 2010, Weakley 2023). Range extent was estimated using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1992 and 2023 (GBIF 2023, iNaturalist 2023, NatureServe 2023).
Occurrences Comments
Based on NatureServe Network occurrence data, herbarium records, and photo-based observations documented between 1992 and 2023, there are between 81 and 300 occurrences rangewide (GBIF 2023, iNaturalist 2023, NatureServe 2023). If records from earlier than 1992 are included, there are greater than 300 occurrences rangewide.
Threat Impact Comments
Threats include invasive plants and logging (NatureServe 2023).
Ecology & Habitat

Habitat

Borodinia missouriensis grows on rocky bluffs, wooded slopes, valley bottoms, and on thin soil around outcrops; it generally occurs on ultramafic, mafic, or 'rich granitic' substrates (Flora of North America Editorial Committee 2010, Weakley 2023).
