Furthermore the large number of small-flowered plants among 
those with yellow flowers is remarkable; 8 of the 42 or 19.0 °/, 
show an average of less than 70 mm. For the plants with red 
flowers the numbers were 10 out of 114 or 8.8°/,. Among the 
grandparents it was just the opposite, the small flowers being red 
and the large ones yellow. If the red flowered plants are further 
separated into those with red leaf margin and those without, the 
green ones comprise in proportion more than double the number 
of small flowered individuals, namely 5 out of 35 or 14,3 °/, as 
against 5 out of 79 with red margin, or 6,3 °/). 
Colour of the flower. 
According to the intensity of the red in the flowers of the F2 
five or six different tints may be distinguished. The yellow varies 
less and not more than three shades can be clearly recognized. 
Between these there are a number of orange colours, so that the 
determination of the number of factors for red will not be easy. 
(See table VIII). : 
The proportion of the numbers of plants with red and yellow 
flowers varies from 2.1: 1 to 4.79: 1 and the same proportion for 
the green leaved individuals from 0.35 : 1 to 1.29 : 1, differences which 
are so great that an independent Mendelian segregation cannot be
