The difficulty in the determination of the species of this genus has led 

 to its being largely neglected by collectors. All of the species reported 

 doubtless have a wider range than is indicated by the citations, but in 

 the desire to have the record reliable no stations have been given unleBS 

 specimens have been examined. The hybridizing of the willows is very 

 general, and adds greatly to the difficulty of determining the material 

 sent for examination. It is believed that the list as given above can be 

 relied upon and will serve as a suggestion to future collectors to devote 

 more care to this interesting genus.
