 In English Botany, ed. 3, Betula verrucosa and B. glutinosa are given 

 as sub-species of an aggregate one, B. alba; and B. glutinosa is made 

 up of two varieties, denudata and jmbescens. 



Betida verrucosa is rather common in our hilly woods and copes, 

 though the larger nimiber of our Birch trees come under the glutinosa of 

 English Botany. 



The Birch is very frequent among the copse wood of the hilly and semi- 

 moorland tracts, appearmg also in the hedge-rows.
