diiction to America. Following its introduction, it has 

 spread both as an ornamental shrub and in its naturalized 

 condition throughout a large area in the cold-temperate 

 belt of our continent. 



The first point where the shrub was introduced into 

 America was probably along the coast of New England 

 where Sir Charles Lyell (2) speaks of it as having been 

 introduced, supposedly as an ornamental shrub. Sir 

 Charles Lyell also attributes its spread toward the in- 

 terior, in a naturalized state, to the agency of animals 

 which eat the berries. In our botanical manuals, it is 

 probably first mentioned as having become naturalized 

 by Bigelow (3) as early as 1813 near Boston.
