Hab. Lake Huron. Dr. Todd. — Mr. Borrer observes that this species is probably the same as Pursh*s 

 R, IcBvigata, since it agrees very well with his character ; but the leaves are pubescent, and the leaf-stalks 

 have no prickles. 



I am indebted to my kind and valued friend Mr. Borrer for the determination of the above species of this 

 most difficult genus. There are still some dubious ones in the Collection, and two or three that are probably 

 new from the Pacific side of the Continent ; but till we are supplied with more copious and better speci- 

 mens, we shall not attempt to define them.
