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 F^ generation were selfed, 

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

In the F^ from coloured plants, we obtain approximately 3 coloured : 

 1 white, and in the F^ from tinged white sister plants we have approxi-
