Rubus prestonensis a rare North American species of brambles in the rose family. It has been found only in the states of Ohio and West Virginia in the eastern United States.[1][2]

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.[3]
