THE WATSONIA 91 



The practical working out of the scheme is 

 revealed in numerous cases that we have already 

 examined. 



Thus, union of our yellow poppy with a white 

 one that produced a crimson progeny finds ready 

 explanation when we reflect that yellow is com- 

 monly formed by the blending of the pigments 

 red and green, and that white is probably due to 

 the blending of yellow and blue. The combina- 

 tion of the yellow flower and the white one may 

 thus be supposed to have resegregated the colors 

 in such a way that yellow and blue were grouped 

 to form white, which was in turn submerged 

 as a recessive factor when coupled with red; 

 the result being that the progeny were all out- 

 wardly red. 



In a similar way may be explained the result 

 of combining the orange daisy with the white 

 daisy; and in general the multiplex presentation 

 of reds and pinks and yellows and whites in the 

 hybrids of poppies and roses and gladioli and 

 dahlias. 



The fact that blue so seldom appears is 

 explained by the assumption that it was the first 

 color to be developed, after green itself, and 

 hence that it is recessive to all the other colors. 

 When a blue is brought out as in the case of my 

 blue poppy, it is unearthed, as it were, with
