VI PREFACE 



briefly mentioned, as are also diseases caused by tbe most 

 common parasitic flowering plants. 



In selecting common names for diseases the authors have 

 chosen those that are most widely used or generally known. 

 In default of any generally accepted name or in cases where 

 the name now in use is ambiguous, as when the same name 

 is applied to more than one distinct disease, they have fol- 

 lowed the plan of giving to the disease a name made by 

 joining to the name of the genus of the causal fungus, with 

 or without elision of the last syllable, as euphony may dic- 

 tate, the termination " ose," signifying " full of." They 

 have also employed this more accurate mode of designation 

 in the text in all cases where it seemed desirable to do so.
