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 
( Lastrea filix-mas). 2. The Broad 
Buckler Fern ( Lastrea dilatata). 3. The Hay- 
scented Buckler Fern (Lastrea recuvv a). 4. The 
Prickly-toothed Buckler Fern (Lastrea sjpinulosa). 
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.
