BEBB WILLOW 



Mexico. It grows on the river baulks and is the first tree or 

 sliriilj in all the northern interior region to spring up on 

 newly formed sand-bars and banks of rivers, holding the soft 

 mud in place with its long rigid roots. It is the herald of 

 the poplars and prepares the river banks for their growth. 

 It is an exceeding!}? valuable tree throughout the entire mid- 

 continental region.

The Bebb AViUow will grow in moist and in dry soil, on the 

 borders of streams and on dry hillsides. It is more abundant 

 in British America than in the United States where it ranges 

 southwest to Pennsylvania and westward to Minnesota. It 

 has appeared, heretofore, in the books as S. rostrahi, but the 

 name, has been changed to S. bebbiana, to commemorate the 

 labors of Mr. Michael S. Bebb who was an authority upon 

 the willows of this country.
