Rubus alumnus, the oldfield blackberry,[2] is a North American species of flowering plant in the rose family. It is native to eastern and central Canada (Ontario, Québec, Nova Scotia) and the eastern and central United States (from Maine south to North Carolina and west as far as Oklahoma, Kansas, and Minnesota).[3][4]
The genetics of Rubus is extremely complex, so that it is difficult to decide on which groups should be recognized as species. There are many rare species with limited ranges such as this. Further study is suggested to clarify the taxonomy.[5]
