THE FLORA, 



Clematis Vitalba L. Alien. In Cleveland in hedges near 

 Whitby ; Aliddleton ! and below the Warren near Guisbrough ; 

 W. Mudd ! I have not seen the localities, but hesitate to accept 

 the species as otherwise than an Alien. It is not clearly known 

 as indigenous in Britain north of South Wales and the Severn 

 province, and is not a plant of Denmark or Scandinavia. It is 

 a species which is frequently planted as an ornamental shrub, 

 and grows subspontaneously in one or two places where it has 

 plainly been introduced, as in Buncombe Park, the woods at the 

 Green near Richmond, and hedges at Sion Hill near Thirsk.
