THE WILLOWS OF OHIO. 277 



more sharply pointed and never pubescent. While both have a 

 bloom on the under surfaces, S. longipes is gray glaucous and 

 S. amygdaloides bluish glaucous. Besides all this their ranges 

 ill i tv t i overlap in Ohio. 



In fruit it is easily distinguishable from either of the other 

 Amygdaleneae. The capsules are similar to those of S. nigra 

 but larger and long pedieelled like those of 5. amygdaloides. 



!.IX AMYGDALOIDES Anders. PEACH-LEAVED WlLLOW. 



ilix amygdaloides grows to medium sized or rarely to a 

 large tree. Its bark and general appearance suggest at once its 

 affinity for the black willow of which it was once considered a 

 variety. Its habit, however, differs very considerably from 

 that of Salix nigra. It is generally sinj timed and very 



shapely, with clean branches and darker brown, smoother bark. 

 The winter buds are nearly twice as lar iliose of Salix nigra, 



dark brown above with a much lighter base where they were pro- 

 by the the old leaf in the fall. Salix amygda- 



loides is well-named for when in leaf the tree, at a little distance, 

 often bears a stnki mblance to a peach tree; the twigs and 



petioles are often reddened and the leaf arrangement is similar to 

 that of a peach tree. Both twigs and leaves are entirely devoid 

 of hairs while young sh t, of the other black willows 



are pu -it. 



The leaves are much broader than in the other members 

 the amygdalenae, ig almost ovate, distinctly broad 



>W the middle with a rounded base and an attenuate fall 

 tip, bright green ab( neath. The venation while 



of the black willow ty; is to approach the regular type, ex- 



emplified by S. (///></; the primaries an . the marginal vein 



short, hardb riding as far as the middle of the leaf, and 



-ork, though very fine is much coarser than in s 

 /, while the econdaries are often more or less regular. 

 Tin- catkins are so similar to th the black willow that
