Parietaria pensylvanica Muhlenberg ex Willdenow. Pennsylvania Pellitory, Rock Pellitory. Phen: Apr-Oct; May-Oct. Hab: In circumneutral soils, such as in thin soils at the bases of calcareous or subcalcareous cliffs or on calcareous shale barrens, rich floodplain soils. Dist: ME west to BC, south to e. NC, w. NC, SC (Gaddy 2014), AL, Panhandle FL, TX, NV, and Mexico (many states).

Origin/Endemic status: Native

Taxonomy Comments: Two varieties (or species) are sometimes delimited (see synonymy): var. pensylvanica, eastern and northern, and var. obtusa (Rydberg ex Small) Shinners, southwestern. This treatment is quite credible, and needs additional assessment.
