While it is true that any generalisations as to branching 

 apply to all parts of the shoot, the subject has acquired a 

 peculiar importance in that region which produces the 

 flowers. This fioriferous branch-system is termed the In- 

 florescence, and it is usually conspicuously different from 

 the rest of the shoot in the sraallness of its leav^es (Bracts 

 and Bracteoles), the slenderness of its internodes if they 

 are elongated, and of course in the presence of the flowers 

 and flower-buds. 



No case of truly dichotomous branching occurs in 

 flowering plants, so that we are only concerned with 

 ordinary branch-systems (monopodial and sympodial) in 

 the Inflorescence ; nevertheless, as will be seen, false 

 dichotomy and other puzzling aiDpearances may be brought 

 about by local peculiarities of growth, and mixtures of 

 both systems may lead to complications of other kinds. 



If we suppose a bud to develope into a shoot by
