306 NOTE ON THE AFFINITY OF FERNS. 
would like to name Calluna Atlantica, and which I have also seen from 
Iceland and the higher Alps. Perhaps some Scottish specimens may 
also be referred to it. In German gardens there is cultivated a Heather 
under the name of Calluna vulgaris flore pleno. It agrees in foliage 
with my C. Atlantica, and does not stand the Continental winters in 
the open air, having to be treated as a greenhouse plant. Possibly 
this may belong to C. Atlantica, but I should not like to commit my- 
self on this and other points connected with the natural history of these 
plants until I have once more an ample opportunity of investigating the 
whole matter. One thing is certain, that botanists would do well to 
look more closely at the genus Calluna than they have done, and not 
assume that it is only composed of one species when Nature herself 
points out to them such important biological differences as those ob- 
served by Dr. Moore.

This rare plant was first discovered in England in 1787, at Lakeby 
Car, near Boroughbridge, Yorkshire, by the Rev. James Dalton, and 
figured in E. Bot. t. 1801, in 1807. Since that date it has been 
found in Thorne Moor, near Doncaster, Yorkshire, on the moss on the 
west side of Bomere Pool, and also on the adjoining Shomere Moss, 
near Shrewsbury, in 1824, by John Jendwine, Esq., Second Master of 
Shrewsbury School; and at Methven, near Perth, by Mr. Duff. The 
careful researches of the Rev. O. M. Fielden, incumbent of Welsh 
UPS Shropshire, have been rewarded by finding this summer 
(1866 ree specimens of it (one of which is now before me in 
Welsh inde Moss, Shropshire.
