and grass will grow under its shade quite as well as in 

 open exposure, and all crops will grow well close to it. 



The buffalo-berry (E. argentea] has been mentioned in 

 the list of native wild fruits (274). It is also valuable in 

 small groups on lawns and in parks. It is a large bush or 

 small tree with silvery foliage, contrasting finely with its 

 dark -red fruit in late summer and autumn. This is

 varieties of the myrobalan, the aucuba-leaved bird cherry,

 the grouping of large lawns and private places. Without 

 pruning they assume regular forms and their dark-green
