3 ASPLENIUM SEPTENTRIONALE. 
has been found only in the extreme northern and western 
districts of England, partially in Scotland, and not at all 
in Ireland, yet wherever it does occur, there it is pretty 
abundant. 
It occurs in clefts of rocks, on mountains, and on old 
walls, and has been found at Craig Dhu, and Carnedd

Fern, and describes it as the Naked Stone Fern (Fdix 
saxatilis Tragi). Ray writes of it under the same Latin 
name, but also calls it Horned or Forked Maidenhair. 
It may be cultivated as we have directed for the 
Asplenium ruta-muraria ; but Mr. Charles Johnson is 
quite right in stating that "it is less adapted for expo- 
sure in the open Fernery, at least in the eastern parts of 
England, the evergreen fronds being liable to suffer 
from frost, and especially during the dry, piercing winds 
of Spring. It will, however, live and flourish when 
planted in a sheltered cavity better than under confine- 
ment If potted, a cold, close frame, where it may be
