275 RubiaC3e i:) : Certainly closely related to the Caprifoliacese and also 

 to the Valeriauacere, Dipsacaceae and Compositse. But in the cruciate opposite 

 leaves, in the capitate inflorescence, and in the floral structure, tliis family is 

 closely allied to the Cornacefe ; some of the Rubiaceae are very near some of
