44 ANNALS OF SCOTTISH NATURAL HISTORY 



P. CALCAREA, Fee (Polypodium Robertianum, Hoffm.). Morven, R. 

 Dick, Smiles' "Life of Robert Dick," 297, 1878. In Sweden 

 it occurs in Dalerne, Oland, Ostrogothia, and Gotland ; in 

 Norway, in Finland, very rare. 



Dr. White says " I am inclined to think that the species 

 may be indigenous in Perthshire, though the opposite opinion 

 may be reasonably entertained." x The only other Scottish 

 reported counties are " Aberdeen, N. error ? " and S. Aberdeen, 

 a very doubtful native. Thus the evidence is against its 

 occurrence in Caithness ; on the other hand, Robert Dick knew 

 the ferns well, and had both the other species by him in plenty 

 to contrast it with ; thus I am inclined to accept it with the 

 usual ?.
