 edges covered, while in the last one side is exposed and 

 one covered. In all cases the exposed edges are bearded. 

 The fruits do not fall, but remain attached to the 

 shrub. This is perhaps because they are arranged for

dispersal by birds. If they fell to the ground they 

 would be liable to be eaten by mice, etc. On the 

 branches, however, they are sufficiently protected by the 

 thorns and prickles. 



If we examine a leaf-bud, say in December (Figs. 

 125-130), we shall find that 

 it consists of a number of 

 scales with three more or less 

 well-marked projections at the 

 apex. In this case the scale 

 itself represents the leaf-base, 

 while the stipules and upper 

 part of the leaf are indicated 

 by the three points. The 

 outermost scale is the shortest, 

 and they gradually increase 

 in length. After about ten 

 of such scales the little leaf- 

 blade becomes much larger,
