Chesapeake Blackberry (Rubus pascuus L.H. Bailey)
↑Notes
We found conflicting reports of this species' origin. BONAP considers it native to parts of the US, but having been introduced to new areas outside its native range as well. POWO considers it native to South Africa only, and introduced in North America. FNA says that it may have originated as a stabilized hybrid between a European blackberry species with a native one, following the introduction of the European species to North America, but does not specify any proposed parentage.
For now, our map reflects BONAP's report, but we are unsure as to which, if any of these theories, is most valid. BONAP is often more rigorous than other sources when covering the North American flora, but BONAP has lagged behind in incorporating the newest taxonomic changes to the Rubus genus specifically, so it could be that this is one instance where their treatment is less correct.
