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.
