Note. 



In determining the willows, we have had the assistance of M. S. 

 Bebb, Esq., Eockford, Illinois, who has made a special study of the 

 North American species. All specimens collected by Dawson, Fletcher, 

 Burgess, Vroora, Bell and myself, have been submitted to him, and our 

 determinations either confirmed or corrected. The synonymy is far 

 from perfect, but it is the best we could do with the materials at hand. 

 Collectors would confer a favor by gathering fruiting specimens in all 

 parts of the country.
