 Clustered Axillary and Terminal Inflorescence. 



FIG. 156. 



Clustered Terminal. 



A TERMINAL CLUSTER of flowers is one that ends 

 the growth of a stem, or branch. Fig. 156. 



Observe that the lowest bud in Fig. 156 is hardly 

 discernible as a flower-bud. The next is a little more 

 advanced, the third still more, and so on till, at the 

 top of the cluster, you see a fully expanded flower. 

 The oldest flowers are at the top or centre of the 

 cluster. This order is often reversed, the oldest 

 flowers being at the bottom or outside of the cluster, 

 and it is important for you to notice this circumstance 

 in studying inflorescence.
