COMMON TREES AND SHRUBS 



young shoots are zigzag and hairy, and produce a leaf at 

 each angle. 



The leaves (Fig. 187, 2) are short-stalked ; the blade is 

 large and somewhat orbicular, with a doubly serrate margin 

 and a pointed apex, and the surfaces are rough and hairy. 

 In the bud the leaves are pleated, i. e. folded between the 

 lateral veins and then upwards along the midrib. 



Buds are formed in the leaf-axils, but the terminal bud 

 dies. In the following year the highest lateral bud grows

into a long, zigzag shoot ; but those below form dwarf 

 shoots, some of which produce a tuft of leaves, while others 

 become flower-buds. Those which will form male catkins 

 do not rest during the winter, but elongate the same year ; 

 hence we find tightly-packed male catkins hanging on the 

 trees in winter (Fig. 187, 1). In mild weather they may 

 open in December, but in severe weather they may remain 

 closed until the end of February or the beginning of March. 

 The Hazel is monoecious. The male catkins (Fig. 187, 1
