This is one of the commonest shrubs in thickets and the margins of pine and oak 

 woods preferring rather dry exposed situations. The smaller fruits and thinner 

 leaves distinguish this plant from the type. In all other characters it is variable. 

 The Japanese form has usually shorter racemes.
