Suggestion, made for the first time, that anthocyanins 

 are formed from chromogens, which are glucosides of 

 flavones, or possibly, xanthones, by the action of oxidase. 

 Successive oxidation stages may give rise to the series, red, . 

 purplish-red and purple pigments. pp. 11, 56, 91, 109, 224
