CHAPTER XI 

 FERNS FOR SPECIAL PURPOSES 



[The matter of nomenclature of the fern family 

 being in a somewhat chaotic state, it has been thought 

 well to give the synonomy according to three of the best 

 known authorities. In the first column the name given 

 as the "standard" is substantially that used elsewhere 

 in this volume, the authority for which is explained in the 

 preface. The other columns indicate the synonomy 

 according to Britton and Brown's "Illustrated Flora of 

 the Northern States and Canada/' and Gray's 

 " Manual." EDITOR.]
