346 HISTORY OF BRITISH FERNS. 



Scotland. It was found so long since as 1841, but, from its 

 close resemblance to AtJiyrium Filix-fcemina, has not been till 

 just now recognized ; and it is probable that it may have been 

 gathered by many persons in many parts of the Highlands, and 

 passed by as the commoner species. The ascertained localities 

 have been thus obligingly communicated by Mr. Watson : 

 Mountains near Dalwhinnie, Inverness-shire, 1841. Great Corrie 

 of Ben Aulder, Inverness-shire, 1841. Canlochen glen, Forfar- 

 shire, 1844. 



This plant is no doubt the Aspidium alpestre of Hoppe ; and 

 is also the Aspidium rlicei/lcum of Swartz, and Polypodium rhteti- 

 cum of Woods, according to Newman. There is, moreover, 

 reason to believe it is the Polypodium rhceticum of Linnaeus, and 

 if this can be satisfactorily settled, the name rhaticum must 

 supersede that of alpestre. It has been already mentioned that 

 Mr. Newman constitutes it a new genus Pseudatliyrium.
