The genetics of Rubus is extremely complex, so it is difficult to decide which groups should be recognized as species. There are many rare taxa with limited ranges such as this. Further study is suggested to clarify the taxonomy.Flora of North America, Rubus Linnaeus, 1754. Bramble
The species is native to Europe but has a few naturalized populations in the eastern U.S. state of Virginia.Biota of North America Program 2014 county distribution map
