CYMOSE INFLORESCENCES 



(/;) The main axis has its lateral inflorescences set closely 

 together to form an umbel, and the lateral inflor- 

 escences are in turn umbels (fig. 73) 



= Compound Umbel. 



Examples — Parsley, Carrot. 



B. CYMOSE INFLORESCENCES. 



In this type of inflorescence every axis grows only for a 

 limited, definite period, and terminates in a flower ; each axis 

 possesses only a very few (usually one or two) branches, and

 order of succession in , the opening of the flowers. Fig. 8i also shows a sympode 

 formed from fig. 80 by the successive displacement of each terminal flower : each dotted 

 line denotes a single axis. 



these latter grow more strongly than the inflorescence-axis which 

 bears them. Usually the flowers at the apex of a cymose 

 inflorescence open before those on the branches, so that they 

 4o not open in acropetal succession. 

 There are three main types of cymes —
