cies. In Webb and Coleman's Report, it is said to be 

 "scarcely naturalized" in Hertfordshire. I have a specimen 

 from the Rev. T. Butler, thi'ough the Botanical Society of 

 London, labelled " Langar," in Nottinghamshire. Mr. 

 Thomas Edmondston stated that he fomid it at Craigmillar 

 Castle, in the Edinburgh circuit, a spot which must have 

 been previously visited and examined by scores of bota- 

 nists. These are all the localities with which I am ac-

 but I should not have published it as a " natm'alized " 

 British species, simply because it lives where planted by

Denizen. Sylvestral. It is doubtful whether this should 

 not rather be called ' alien ' than ' denizen.' Though ad- 

 mitted into our floras from the time of Ray, there has usu- 

 ally been some expressed or implied suspicion of its being 

 an alien in England. Hooker marks it an introduced spe- 

 cies. Babington admits as a true native, without any in- 

 dication of doubt. The few localities in which it has been 

 seen by myself, were so apparently the result of a former
