which the F 2 is considerably less heterozygotic for the other factors 
than the F 1. Clearly, in any case, there was no independent Mendelian 
segregation for the factors of the wax layer and the ratios in the 
various batches sown showed even greater divergence than those of 
red and green. (See tables III). 
There is an appreciable repulsion between the factors for the red 
leaf margin and those for the wax layer. This is best seen by 
observing how many red and green individuals there are without 
wax. The number of red ones is then found (except in the fourth 
sowing) to be the larger, sometimes 2-3 times as large and on 
the average 1,78 as large as that of the green, whereas the ratio 
red to green was originally 1,15: 1 and was not displaced, through 
the slightly larger mortality of the green individuals, beyond the 
ratio 1,30: 4, d 
The number of staminodes. 
C. indica has two staminodes. In a few flowers, however, an 
indieation of a third is found in the shape of a red filament, generally 
not longer than a few millimeters. 
C. glauca has always three staminodes. The Fl of the crossing 
has 3 and the vast majority of F2 also 3. 
The. number. of plants with 2 or 2-3 staminodes varies rather 
considerably in the different sowings, the last three furnishing many
