There is a peculiar interest attached to this very elegant 

 Pern, from having been so recently discovered as a British 

 species. Tlie similitude of the Alpine Lady Fern to the ^45- 

 plenium JiUx-fcemina no doubt was the cause of this species 

 being entirely overlooked, although now it is found to be in 

 some of its Scotch habitats exceedingly abundant. In 1841 ^ 

 Mr. Watson gathered it on the mountain Ben Aulder, in In- 

 vernesshire; and in 1844, a frond was brought from Canlochen 

 Glen, in Forfarshire. In 1852, Mr. T. Westcombe and Mr. 

 Backhouse procured it in great abundance in Canlochen, in
