CHAPTER X. 
THE BUCKLER FERNS. 
Plate 6. 
HE Buckler Fern group includes 
some of the finest of our native 
species; namely: 1. The Male Fern 
(Lcistrea filix-mas). 2. The Broad 
Buckler Fern ( Lcistrea dilatata). 3. The Hay- 
scented Buckler Fern {Lastrea recurva), 4. The 
Prickly-toothed Buckler Fern (. Lastrea spinulosa). 
5. The Mountain Buckler Fern ( Lastrea montana ) : 
and 6. The Marsh Buckler Fern (. Lastrea thely- 
pteris) . The common name of Buckler Fern is 
no doubt somewhat fanciful, having probably been 
suggested by the peculiar shape of the scale cover¬ 
ings of the little clusters of spore-cases attached 
to the backs of the fronds.
