Obs. This small tree which is also called Ironwood in the 

 Northern and Eastern States, is readily distinguished from the 

 former by its somewhat shaggy bark and differently formed stro- 

 biles, or seed vessels : these in the present tree being so similar 

 to those of the garden hop as to have given it the appropriate 

 name of Hop-hornbeam. It is likewise frequent in this locality 

 being found in company with the preceding. Its wood is also 

 hard and strong; but the size of the tree being inconsiderable, it 

 is susceptible of no very useful application. Flowers about the 

 1st of April.
