 N.B. Localities are also on 



record for this tree in several 

 counties of the four first 

 provinces, from Cornwall to 

 Norfolk. With few except- 

 tions it is indicated only as 

 an introduced or planted 

 tree in those counties. I 

 have received the American 

 P. serotina, labelled as wild 

 Padus, from two of the 

 southern counties. (10 11 



17 19 20). [2 7].

 108 110 to 112. Two 

 practical difficulties arise in 

 attempts to trace the dis- 

 tribution of this tree. First, 

 in many books and lists the 

 name Cerasus is used indis- 

 criminately for either or both 

 the species. Second, the 

 widest diversities of opinion 

 occur as to- the indigenous 

 or introduced character of 

 each species. For the coun- 

 ties of South Britain the 

 Avium is usually treated as 

 native. For those of North 

 Britain it is usually noted as 

 probably introduced. For 

 the counties of Mid Britain 

 there is an approximate 

 balance of opinions ; some 

 for, some against nativity. 

 No doubt the seeds are 

 still carried in the crops of 

 birds, from gardens to wilds ; 

 but whether the origin has 

 been really from gardens, at 

 first, or from wilds to gar- 

 dens, cannot be satisfactorily 

 decided now.
