A COMMON British Fern, yet less common on the eastern 

 side of England. Delighting to grow on old walls, both brick 

 and stone, and more especially on the northern side, and 

 preferring to mount up the walls as high as possible: this I 

 have seen in many instances. In the drier situations dwelling 

 alone, and in the more moist having as its companions 

 Asplennmi trichomanes, Ceterach ojjicinarum, and Cystopteris 

 fragilis. Also found on rocks, church towers, bridges, and 



rums. 



Found in the Isle of Wight, and North and South Wales. 

 The Island of Anglesea, Priestholme Island. In Sullan, Orkney, 

 Ireland, Isles of lona, Cantyre, Islay, Harris, Lewis, N. Oist, 

 Arran, on Ailsa Craig, and in Jersey. 



Abroad it is a native of Russia, Norway, Scandinavia, 

 Holland, Belgium, France, Spain, Italy, Portugal, Germany, 

 Switzerland, Hungary, Transylvania, Croatia, Greece, Dalmatia, 

 Bohemia, Sicily, Corsica, Turkey, the Crimea, North and South 

 Africa, in Asia, and North America. 



A difficult Fern to cultivate, requiring much stone in the 

 soil, and a dry atmosphere. 



The fronds, which are deltoid, are bitripinnate, varying from 

 one to six inches in length. In the young state simple and 

 reniform, or trifoliately pinnate, and in this state often fertile. 



The pinucE alternate.
