Ewing, of Norwich, who sojourned in Bristol about 

 1830. See note by Dr. Thwaites in the Phytologist, 

 I. 75. Swete (Fl. 97) writes that at his date its 

 area was " not more than half a mile," implying 

 that it occurred over a considerable space, which is 

 to some extent confirmed by Dr. Thwaites, loc. cit. 

 Undoubtedly the fern has shared the fate allotted 

 by collectors to all good things ; for the late Mr. 

 W. W. Stoddart spoke of it ten years ago as being 

 only obtainable with the aid of a quarryman and a 

 rope, and other information is to the same effect.
