Culture.— This is a Fern which it has been said is very 
difficult to cultivate ; and one reason alleged for this is that 
it is not easy to imitate the conditions under which it grows 
in a wild state. Being a mountain Fern, it grows at con- 
siderable elevations, where it is subjected to less atmospheric 
pressure than it gets when grown at a lower station. There 
may be some force in this suggestion. We have, however, 
seen Polystichum lonchitis grown very successfully in the
