Rubus frondosus is a North American species of flowering plant in the rose family. It has been found in Ontario and in the eastern and central United States from Maine south to Georgia and west as far as Oklahoma, Nebraska, and Minnesota.[2] Common name is leafy-bracted blackberry.[3]
Rubus frondosus has pinnately compound leaves with 3 or 5 leaflets. Flowers are white. Fruits are black.[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]
