THE FERN WORLD 
it is found almost everywhere, being pretty equally dis- 
tributed throughout Great Britain, Ireland, and the Channel 
Islands, 
Culture. — In open rockwork, or in any part of the Fern 
garden, elevated situations are the best for this Fern. It 
must he kept moderately moist at its roots, hut they should 
have good drainage. The soil should be leaf-mould and 
sand or sandy loam, and there should be plenty of room for 
its rhizomas to travel. In planting them they must not be 
covered with earth, but merely pressed down into the earth, 
so that about half their circumference is covered, the root- 
lets only being embedded in the soil. Shade, coolness, and 
shelter from cutting winds are essential in its cultivation 
out of doors. Great depth of soil is not necessary. In 
shallow pots also Polypodium vuhjare may be grown very 
successfully, and under glass in the Fern house or the Fern 
case, although, from its hardy nature, it lives and will thrive 
better in the freedom of the outdoor fernery. If it be 
desired to increase this Fern by division, this can be easily 
accomplished by cutting the rhizomas into pieces, taking 
care that each piece has a little mass of rootlets and one or 
two fronds or frond buds.
