THE SEA SPLEENWORT. 
It keeps very close to the sea-level. In cultivation it 
requires warmth, and grows best in sandy peat-soil, 
in the interstices of stones or rock- work. 
The Sea Spleenwort is most abundant on the west 
coast of Europe, extending, however, eastward in the 
Mediterranean. It is found also on the African coast, 
in the Western Isles, and, according to Sir W. Hooker, 
in St. Helena. This peculiar distribution has been 
supposed to indicate that it took place prior to the 
great disruption of the chalk and the vast deposit of 
alluvial matter along the eastern coast of England.
