COMMON HARTS TONGUE . 
this suprasoriferous (bearing-the-sori-on-the-upper- 
surface) condition. 
The Hart’s Tongue seems to be pretty generally 
distributed throughout England, Scotland (more 
sparingly), Ireland and the Channel Islands, and 
through most countries in the northern temperate 
zone. It is not a sea Fern, but prefers the coast 
neighbourhood in more northern latitudes, ranging to 
an elevation of some 500 or 600 feet. With all its 
varieties, it is hardly to be considered a common Fern. 
It may be easily cultivated, and no Fernery should be 
without some few at least of its endless changes. 
Medical virtues have been attributed to it; among 
others, that of being good for burns and scalds. It is 
abundant in the limestone districts, and found also 
here and there upon the slate.
