74 A FLORA OF GLAMORGANSHIRE 



but in cases where the plant is usually found on rubbish-heaps or 

 plainly as a ballast introduction, any cornfield occurrence at once 

 becomes of less value. It would be impossible to say that Ranun- 

 culus arvensis, R. sardous, Brassica Napus, &c> are not native 



anywhere in the county ; but I am forced to the conclusion that it 

 is very unlikely that they are native. 



In my opinion, the occurrence of annuals in cornfields, on 

 rubbish-heaps, dock ballast, &c, and nowhere else in the county, 

 makes it more probable than not that they are not native within 



•the area.
