Tables i — 26. 



Explanatory note. In the majority of these tables, the various races are 

 cited by pedigree number rather than by name. The number and name are both given 

 in the body of the paper under "materials and methods". Tables 21, 22 and 25, 

 representing the character of certain Fj populations, were tabulated from selected plants 

 and not taken from plant after plant as they stood in the row. These selected plants, 

 however, represent practically all the various types that appeared. In all other tables 

 of the same type, the plant numbers represent the plant populations as they stood in 

 the row in the field-plots. 



These tables are so constructed that a definite unprejudiced conception of the 

 variableness of the expression of the fasciation factor may be easily gained. Take, for 

 example, the character of plant number 1 in Table 6. 25 flowers were examined; 

 15 had 5 sepals, 9 had 6 sepals and one had 7; 8 had 5 petals, 11 had 6 petals and 

 6 had 7 petals; 10 had 5 stamens, 10 had 6 stamens, and 5 had 7 stamens; 12 flowers 

 had 2 ovary-locules while the remaining 13 had 3. This plant was 19 "0 dem. high at 

 maturity and had 27 leaves. The figures within circles ((14)) are floral leaf class range 

 numbers placed thus to avoid lengthening the table. In tabulating the inheritance of 

 calycanthemy, O'O represents absolute absence of this condition, 0'5, its presence on a 

 portion of 1 sepal, 1*0, 2'0, 3'0, its presence on 1, 2 and 3 sepals.
