within Moray or Eastern Inverness. In 1844, I brought 

 a frond of it from Canlochen Glen, in Forfarshii-e. These 

 specimens (except the second from Ben Aukler, given to 

 Mr. Babington) remained in my herbarium until 1851, 

 first doubtfully labelled, and then temporarily forgotten. 

 Their close resemblance to small fronds of Athyrium 

 Filix-foemina made me feel very uncertain whether they 

 could be properly referred to Polypodium, until Mr. 

 Newman (to whom the Canlochen frond was at length 

 shown, when again recollected) decided it to be Polypo- 

 dium alpestre. Now that it is known to be a native of at 

 least two Highland counties, we may reasonably expect 

 that it will be found in other counties by botanists who 

 seek it in the knowledge of its close resemblance to Athy- 

 rium Filix-foemina, for which latter fern this species may 

 readily have been mistaken and passed by.

Native. Rupestral, &c. It may at first appear an error 

 to refer this fern to the Scottish or boreal type of distri- 

 bution, when the zonal and latitudinal ranges are so wide 

 or general, extending from the coast level to the high 

 mountains, from the south of England to the extreme
