Rubus meracus

Rubus meracus is an uncommon North American species of brambles in the rose family. It grows in the central United States, in the central Mississippi and Ohio Valleys and the Great Lakes region.

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.
