It is very probable that most of the sub-tribes of the Cichoriese 
are artificial, therefore it is not considered desirable to discuss their 
affinities. The derivation of type I styles from type IV has already 
been mentioned and as the stamens are of a relatively simple type 
a derivation of the Cichorieae from the Senecioninae is rendered 
probable.
