34 ALIEN FLORA OF BRITAIN 



Cucubalus baccifer, L. Native in woods and bushy 

 places in Europe and Northern Asia. It is common 

 in Central Europe, becomes rare in Northern France 

 and Belgium, and, in England, has only been recorded 

 from the Isle of Dogs in London, where it was doubt- 

 less introduced by some accident, and has long since 

 disappeared. 



[Dianthus Anueria, L. Native of dry wood borders 

 in many English counties, as it is in Normandy and 

 Belgium. The species has, however, long been cultivated 

 in gardens, and is much more commonly recorded from 

 waste places and hedge banks, where it is of garden 

 origin.] 



Dianthus barbatus, L. Indigenous in the mountain 

 pastures of Southern Europe. This plant, the Sweet 

 William of gardens, has occasionally been observed as 

 established on old walls, where it had obviously escaped 

 from culture. 



[Dianthus csesius, Sm. Native on Cheddar Cliffs — an 

 outlying station, as its range almost terminates on the 

 North Coast of the Continent. It is often grown 

 in gardens, and is rather frequently recorded as growing 

 spontaneously on walls in their neighbourhood.] 



Dianthus Carthusianorum, L. An occasional escape 

 from garden culture. 



Dianthus caryophyllus, L. This favourite garden plant 

 is indigenous no nearer than the rocky hills of Southern 

 Europe. Further north, and in England, it is an occa- 

 sional stray on old walls and in hedges near gardens.
