It grows in the central United States, in the central Mississippi and Ohio Valleys and the Great Lakes region.[2][3] 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.[4] References1. ^The Plant List, Rubus meracus L.H.Bailey 2. ^Biota of North America Program 2014 county distribution map 3. ^Bailey, Liberty Hyde 1943.
