S. IKENO : 
ns clearly to understand the genotypic constitution of all colour-varieties used 
in my experiments, except some few races. The behaviour of the various 
hybrids of flesh-coloured race was studied till F 2 , and I think I am now able 
to make a certain conclusion about its genotypic constitution, but since my 
experimental results concerning this race are not yet complete, I will defer 
their publication to a future paper. 
Flower-Colours. 
The following colour-varieties were used in my experiments, viz. white, 
yellow, orange, flesh-coloured, red, and magenta (PI. II). Besides, I could 
distinguish clearly two kinds of white, which are almost alike in external 
appearance, and yet genotypically different ; they are called here white-I and 
ivhite-II respectively (PI. II, fig. 7-8). 1 
The colours of all parent varieties as well as their i^-hybrids were 
recorded by means of “ Klincksieck et Valette, Code des Couleurs ” (Paris, 
1908); the results are indicated in the following Table :—■

1 I think that I have discovered still another race of white, which is externally quite 
similar to white-I, and yet genotypically different from it. I will call it white-III) its behaviour 
will be described below (p. 120).
