LXX. CORYLA CE^ : STRYa. 



919 



As it shoots out into numerous widely spreading, horizontal, irregular 

 branches, it cannot be regularly trained up with a straight clear trunk. The 

 leaves are much smaller than those of the common hornbeam, and the branches 

 grow closer together ; so that it is even still better adapted for forming a 

 clipped hedge than that species. Very hardy, and easily propagated by layers.
