| Distribution | Weakley (2024) has this species listed as occurring in NC. SERNEC has specimens from Catawba County from 1956. This seems to be a recent split, or at least a re-defined split. As a result, the species is very poorly known to regional botanists, and its NC range is not known.

| Abundance | Completely unknown, but this is clearly a more Northern species, common in the Ohio Valley states and some states to our north. Thus, probably genuinely rare in NC. However, the website editors simply give a State Rank of SU = Undetermined. | |
