MOUNTAIN BUCKLER FERN. 45 
observation. He says: “ Immediately the fronds 
begin to unroll, they exhibit the pinnae placed at 
right angles with the main stem, and are not con¬ 
volute, as in the allied ferns.” 
Many persons complain of great difficulty in rearing 
or establishing Nephrodium Oreopteris, which after a 
time fades and dies, and it is almost impossible to 
cultivate it with other ferns in a closed case, as it 
requires so much more moisture than most others. 
The best plan to secure its continuance is to transplant 
it with some of its native earth into a pot with pure 
loam, and to keep the soil wetted during the winter, 
either by a constant flow of water from a siphon, or 
by a saucer full of water, in which it may stand. The 
first plan appears the best, and might be adapted to a 
green-house or rock-work, in which the fern might be 
planted. Each plant seems to adapt itself to the 
circumstances by which it is surrounded in its earliest 
state ; and in transplanting wild ferns it is well to 
observe these closely, and adapt the artificial treat¬ 
ment as much as possible to them, not following 
exactly any one rule for the treatment of any one 
species. There is no difficulty in obtaining young 
shoots of this fern, as the seedlings are always most 
abundant.
