FERN GROUPS. 
HERE is r 
world; and although we do not 
propose strictly to adopt the dis¬ 
tinctions made by botanists, we 
shall observe a certain order in arranging 
our favourites. Hitherto we have described

scribed, each one stands alone, and is, so far as 
Britain is concerned, the only species of its genus. 
In treating of these, we have not thought it neces¬ 
sary to place them according to any particular 
method of arrangement. There is a certain rela¬ 
tionship existing between the Moonwort and the 
elationship in the Fern-
