In order to investigate the meaning of these results which are in 

 disaccord with those obtained hitherto with coloured stemmed whites, 

 coloured and white tinged plants of the Fi generation were selfed, 

 and the F, generation examined. The results were as follows: — 



F^ from coloured flowered F^ plants. 



Experiment No. 20*2, a magenta plant selfed. 



^2. Observed 20 coloured : 8 white and flaked white.
