509. LoNiCERA Caprifolium, Linn. /^J^/fj(f.ft.£f^g 



Area (12345*7*9 10** 13 14). 



Alien ? Localities are recorded for this species in some 

 sixteen counties ; that of Cambridge being the only one 

 which gives occasion to a doubt whether the designation of 

 " alien " be strictly con-ect. Professor Henslow marks the 

 name in his Catalogue, as that of a species possibly intro- 

 duced, but not certainly so, in Cambridgeshire ; and in the 

 Manual of British Botany, Mr. Babington applies the same 

 mark. In a manuscript note, recently received from the 

 Author of the Manual, he observes, " Lonicera Caprifolium 

 is, I think, a native of this [Ouse] district. It is found in 

 many old thickets, at some miles distance fi-om each other, 

 in Cambridgeshire." On the other hand. Dr. Bromfield 

 thinks that " geographical considerations are opposed to 

 the idea of the species being truly indigenous to this coun- 

 try, though decidedly a well-naturalized plant in several 

 parts of the kingdom." (Phytol. iii. 421.)
