Native. Sylvestral. The Lake province has not been 

 reckoned in the estimate, because so conspicuous a plant 

 seems not very likely to have been overlooked by botanical 

 tourists there ; although the occurrence of the Serratula in 

 the adjacent provinces, Tyne and West Lowlands, would 

 otherwise create a presumption in favour of the Lake pro- 

 vince also. It may possibly rise to the superagrarian zone 

 in the North of England.
