thickets on the borders of our mountain brooks and 

 swamps and fringes on the banks of the larger streams. 

 The few merely named below do, however, attain the 

 stature of small trees. No attempt will be made to char- 

 acterize these as it would require more space and fuller 

 botanical descriptions than this bulletin contemplates.* 

 Everyone knows a willow, knows where willows are to be 

 sought and knows, too, something of their uses. The 

 following are the species that may be included among the 

 trees of the state: 



(1) ALMONDLEAF WILLOW. 



(Salix amygdaloides Anders.) 



One of our largest and most widely distributed tree- 

 like willows. It is generally spoken of simply as the 

 44 common willow." 



(2) WESTERN BLACK WILLOW. 



(Salix lasiandra Benth.) 



The Wyoming form of this willow is considered only 

 a variety (var. caudatd) of the species as written above. 

 It ranks with the preceding in size and is widely distrib- 

 ted in the state. 



(3) BEBB WILLOW. 



(Salix Bebbiaria Sargent) 



Though never large it is decidedly tree-like on ac- 

 count of its usually single trunk and rounded bushy top. 



It seems doubtful whether any of the other numerous 

 species attain such a size as to be called trees. 



*Possibly sometime in the future it may seem of sufficient importance to issue a special bul- 

 letin on our Willows and their uses. The entire list and the means of recognizing them may 

 then be given.
