« Salix Piped Bebb (Gard. and Forest, VIII. 4S2, 189$ Sargent. Suva, IX. 145, 1896), several individuals 

 of -which are known to occur in the vicinity of Seattle, Wash., appears not to be arborescent. In 1896 it 

 was included with our arborescent willows in the belief that eventually it -would be found as a tree. As 

 such a form has not been discovered, it seems best to exclude the plant from our tree flora.
