Variegated Leaves. 287 



of the third group. The more yellow seedlings there 

 were in a group the more variegated specimens did it, 

 as a rule, also contain. I collected tlie seeds of a yellow 

 fruit separately ; only eleven of these germinated but 

 these had all pure yellow cotyledons. On the other hand 

 striped fruits had percentages of variegated seedlings 

 which varied greatly, and this was also true of the striped 

 parts of capsules when their seeds were harvested sepa- 

 rately. Lastly the seeds of green capsules produced only 

 green seedlings. 



The color of the seedlings is therefore to a larsfe ex- 

 tent determined by the color of that part of the mother 

 plant wln'ch produced the seed (and also the pollen). 



I made a further investigation of the seedlings from 

 seeds of green and variegated branches of individual 

 plants in various other species, after artificial isolation 

 had been secured, either by means of parchment bags, or 

 by planting the plants some distance apart, or by making 

 them flower at different times. ^ I obtained the following 

 percentages of variegated and yellow seedlings : 



The high percentage of green plants in Arah'xs alpina 

 corresponds presumably to the readiness with wliicli tliis
