- Comments
- A distinctive, shorter and thiner-stemmed plant with dissected leaves even in the basal rosettes. The Flora of Virginia and Weakley (2012 Draft Flora of the Southern and Mid-Atlantic States) treat this taxon as var. beadlei (Small) Fernald, a narrower Southern Appalachian segregate included in var. pinnatiloba by most authorities. This might make sense given the somewhat geographically disparate and environmentally heterogeneous nature of the latter. However, Weakley also states that "it is not at all clear that this taxon [var. beadlei] is distinct." So until further clarity on this is achieved, we are following the more traditional and conservative approach of FNA and others.
- Habitat
- Palisading, riverside limestone and dolostone cliffs; also reported (not vouchered) from a calcareous siltstone cliff on Clinch Mountain; occurs in crevices of the rock faces or in thin soils on ledges and clifftops. Rare, sw. mountains.
