striped Flowers 319 



half wholly red. Four individuals were found 

 with only uniform red flowers. These were iso- 

 lated and artificially pollinated, and the same 

 was done with some of the best striped indi- 

 viduals. The seeds from every parent were 

 sown separately, so as to allow the determina- 

 tion of the proportion of uniform red individ- 

 uals in the progeny. 



Neither group was constant in its off- 

 spring. But as might be expected, the type 

 of the pistil-parent plant prevailed in both 

 groups, and more strongly so in the instances 

 with the striped, than with the red ones. Or 

 in other words seed-reversions were more nu- 

 merous among the already reverted reds than 

 among the striped type itself. I counted 2^ 

 reversion in the latter case, but 2^^ from the 

 red pistil-parents. 



Among the striped plants from the striped 

 pistil-parents I found some that produced bud- 

 variations. I succeeded in isolating these red 

 flowering branches in paper bags and in polli- 

 nating them with their own pollen, and subjected 

 the striped spikes of the same individuals to a 

 similar treatment. Three individuals gave a 

 sufficient harvest from both types, and these 

 six lots of seeds were sown separately. The 

 striped flowers repeated their character in 98;^ 

 of their offspring, the red twigs in only 71^, the
