647. Americana, Lin. C. Grotwvii Willd. On Epilobii, Polygonii, etc., on 



Belle Isle. Common. The Linnean C. Americana was primarily

 The West Indian and South American plant was eliminated in 1818 

 by H. B. K. in Nova Genera et Species, etc., Vol. 3, 122, and described 

 under the name of C. graveolens, under which name it should be 

 known, allowing C. Americana to stand for the plant to which 

 Linneaus intended it to apply.
