Native. Rupestral or Sylvestral. Either overlooked by 

 collectors or very local. Has been found at Stapleton and 

 Hanham, near Bristol, and also at Tintern, Monmouth- 

 shire, by Mr. Thwaites, from whom I have a series of 

 sjDecimens. Exactly the same plant has occurred very 

 sparingly, on and under an old and much shaded garden 

 wall, near the church at Long Ditton, Surrey. Having 

 allowed it to seed and repeat itself in my garden, for some 

 years, as an introduced weed, and thus kept it constantly 

 under observation, I do not hesitate now to separate it 

 from E. montanum. It can readily be distinguished from 

 the latter at all seasons, and in December quite as well as 

 in June, after having been once clearly known by sight. 

 Probably, however, it is confused by authors with narrow- 

 leaved states both of roseum and of montanum. (See vol. 

 i. page 371.)
