THE FERN WORLD 
it may happen that they are not so rare as is generally

abundant could a thorough search be made in the lofty, rocky 
situations which they prefer to inhabit. At the pass of 
Llanberis in Carnarvonshire, they are also found growing 
upon a kind of limestone rocks. 
Culture. — From its small size and elegant form, this little 
Fern is especially adapted to cultivation in the Fern case 
upon miniature rockwork. But it may be grown in the open 
rockery, in pots, or in the Fern house. It is essential, how- 
ever, that wherever planted it should have the most perfect 
drainage, and must be kept moist and cool in a shady nook. 
It should be planted between small blocks of stone, in a soil 
composed of light peat and light loam, in equal proportions, 
together with clear sand equal to about one-fourth of the 
whole. It will be advantageous to mix in the soil some small 
pieces of sandstone rock.
