CONSPECTUS: DISTRIBUTION 7 



The widest gaps, it will be observed, are between Cruciferae 

 and Rosaceae and between Hypericaceae and Begoniaceae, but 

 these I believe represent nothing more than lack of knowledge. 1 



I give below a list of genera within the limits of which one 

 or more species are now said to be subject to attack. Many 

 of these genera contain plants of great economic importance. 

 Where I have some personal knowledge of the subject I have 

 italicized the genus name, and in what follows the reader will 

 naturally expect me to draw illustrations principally from the 

 diseases most familiar to me.
