 ties of Devon, Somerset, Brecon, Montgomerj^, Merioneth^ /j-o : 

 and Caernarvon ; possibly so, in Yorkshire, Westmoreland 

 and Ciimberland. Reported from those of Denbigh and 

 Dumfries ; but in these it may not be truly native. Intro- 

 duced to the counties of Edinbm-gh, Kim-oss, Aberdeen and 

 JNIoray. Mr. BoiTer deems it indigenous in the Lake pro- 

 vince, where Mr. Winch thought it introduced. The Cum- 

 berland localities in which I have observed it, were sus- 

 picious from their proximity to houses and gardens ; and I 

 give it as a native of that pro\'ince on account of Mr. 

 Bon-er's opinion, who may have seen more reliable locali- 

 ties. It thrives and seeds fi-eely in Siurey, where some- 

 what shaded by trees or walls, in gardens.
