supposition is the correct one, and it may not be out 

 of place to give one instance which supports this view. 

 We sometimes find on the branches of cocoa plants 

 very small twigs, only a few millimetres long, which 

 bear flowers. These twigs no longer look like dichasia, 

 because they are woody, and in addition they bear 

 small scales, arranged according to the formula J, in 

 the axils of which the flowers appear (Fig. 13, A). By 



FIG. 13. Very small twigs such as sometimes appear on the branches and stem 

 (enlarged 1). 



They bear scales arranged in the same way as the leaves on the normal twigs (see Figs. 5 

 and 6), and one flower or one flower-bud in the axil of each scale. In the twig in B one of the 

 scales is replaced by a leaf. 



this arrangement of the buds, those small twigs resemble 

 leaf-bearing twigs ; and this is still more the case when 

 such a twig bears not only flowers, but also leaves, 

 though the latter are always small. An instance of 

 such a case is given in Fig. 13, B. Thus these twigs 

 form apparently a link between the true leaf-bearing 

 twig and a true blossom-bearing twig (called also flower- 

 cluster or dichasium). 



In trees of five years old or more the third-eldest
