THE FERN BULLETIN 



that has been thought worthy of a variated name. Of 

 these there are no less than 121 among the ferns and 

 82 among the allies. A large majority of these have 

 been described in the past few years, and many of them 

 represent merely small changes in the texture and cut- 

 ting of the leaves due to variations in the habitat of the 

 plant. Still others are forms that were once considered 

 species but which further study has shown to be un- 

 entitled to rank as such. 



It was inevitable that while this list was being 

 printed a number of new forms and species should 

 have been added to our flora. These have been listed 

 below with places of publication given when the forms 

 are new.
