that, in well-grown specimens, they form quite 
a cup or hollow, and give the appearance of a cir¬

Under cultivation the same conditions will apply 
to Angulare as those which apply to Aculeatum. 
The latter, however, appears more hardy and 
better able to withstand the frosts, doubtless on 
account of the more evergreen, rigid, and vigorous 
character of its fronds. Both Ferns are beautiful; 
but there is a soft beauty and a gracefulness of
