Hab. Canada. Mich. About Lake Huron. Dr. Todd. — Well distinguished as a species, first by Dr. 

 Bigelow, tbeu by Mr. Elliott, from A. rubra. The pedicels are remarkably thickened, as large as the 

 peduncle. The berries milk-white, tipped with red, smaller than in the last species, about 8-seeded, on 

 short red pedicels. Dr. Bigelow justly observes that the foliag^e of these two is exactly similar to that of 

 our Europsean A. spicata, with which Michaux coufouuded them. I possess beautiful specimens of both 

 the American species gathered by Dr. Boott near Boston, U. S.
