Area (5). 



Alien ? This is given as an undoubted native in Ba- 

 bington's Manual of British Botany, with the following 

 habitat : " Near Shrewsbury, Rev. W. A. Leighton ; " and 

 from that locality I have been favored with cuttings of the 

 species by Mr. Leighton himself From Mr. Borrer, how- 

 ever, I learn that the habitat is purely an artificial one, and 

 consists only of a few trees planted in a hedge-row; and 

 where, I understand, they were observed by Messrs. 

 Leighton and Babington in 1843. It is to be regretted, 

 under the circumstances, that the species should have 

 been given as a true native, without explanation, in the 

 work mentioned. Has it, or has it not, been found also in 

 Westmoreland .''
