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 the 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 large ex- 
tent determined by the color of that part of the mother 
plant which 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. 1 I obtained the following 
percentages of variegated and yellow seedlings :

Arabis alpina 2-10 % 90 %

The high percentage of green plants in Arabis alpina 
corresponds presumably to the readiness with which this 
species produces bud-variations, variegated branches be-
