setts. This species has broad, oval, dark-green leaves, 

 sharply and irregularly toothed, which are whitish 

 and downy beneath. The smooth alder (Alnus ser- 

 rulata) is found southward and 

 south westward from Massachu- 

 setts ; it forms dense 

 thickets in Pennsyl-

 on the borders of 

 swamps, and farther

 of thirty-five feet. The 

 leaves are obovate, and
