SALICACEAE 

 Willow 



Salix, (Tourn.} L. 



The genus Salix is represented in Michigan by thirty or more 

 distinct species, and there are many more hybrids. The majority 

 of these are shrubs, only a few becoming truly arborescent. 

 Because of the similarity of their botanical characters, the fre- 

 quency with which they 'hybridize, and the facility with which 

 they respond to their environment only an expert is competent 

 to identify the species so abundant along our water courses and 

 on the banks of our lakes and swamps. The scope of this work 

 being necessarily limited, it has been deemed best to describe 

 but two of our native willows and two of our foreign neighbors 

 which are frequently planted.
