PREFACE 



This Index to the last ten volumes of The Fern 

 Bulletin is divided into three parts, viz : — A General 

 Index, containing the titles of all articles closely 

 cross referenced ; a second part, Pteridographia, con- 

 taining most of the short notes and unsigned articles ; 

 and an Index to Species containing the name of 

 every fern, as it appears in the text, about which 

 anything is said which might prove of value in its 

 study. 



Illustrated articles are marked with a star (*), 

 articles containing descriptions of ferns are indi- 

 cated by a dagger (t) arid descriptions of new ferns 

 are indicated by a double dagger ($)•
