tions and found that the "white" were not pure white 
but pale lilac. Then I kept only plants of this variety 
through the winter, and first examined them in 1894, 
when they were in full flower. They flowered in isola- 
tion and partly pollinated themselves with their own 
pollen, partly were fertilized by insects. In later years 
also I have not enclosed this species in bags but have 
either grown them in an isolated position and left them to 
be pollinated by insects, or have had them flowering in 
a little greenhouse entirely built of fine metal gauze, 
where they fertilized themselves. 
My object was to test the degree of inheritance of the 
pale, the lilac, and the violet types separately. I shall 
first give a summary of my experiment. In this table, W 
denotes whitish, L lilac, and V violet (that is, the color 
of the wild species). The numbers in each case are per- 
centages of the particular culture ; where the culture was 
too small I have omitted the numbers.

Before I come to the description of this experiment 
it is necessary to give some more details as to the varia- 
bility of the color of the flower.
