Rubus spectatus

Rubus spectatus a North American species of brambles in the rose family. It grows in eastern and central Canada (Quebec and Ontario) and the northern United States (New York, Michigan, and Indiana).
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.
