BUDS AND STIPULES 



eighth, but much shorter and smaller. The stipules 

 are large, particularly on the leafy shoots ; but they 

 develop after the leaves are expanded, or during that 

 process. Some forms are exstipulate. 



The winter-buds of the White Willow (Salix alba) 

 are all axillary ; the terminal one, as well as the tip of 

 every shoot, dies. The buds are oblong, obtuse or sub- 

 acute, compressed antero-posteriorly, but tumid on the

anterior face (fig. 178), thickened at the edges, and have 

 a thickened suture (fig. 179) along the middle of the 

 posterior aspect. The cap-like scale seems to consist 

 of two leaves united ; its thickened edges and the 

 strong, slightly branched nerve, easily seen on the 

 inner face of these thickened edges, tend to support 

 this view ; but no suture is discernible on the ante- 

 rior face. When growth recommences in spring, 

 the scale bursts along the suture on the posterior 

 face (fig. 180).
