to high humidity and temperature as the factors favoring the 

 expression of abnormality. Under unfavorable conditions of 

 humidity and temperature, the influence of starvation and lack 

 of water upon the degree of abnormal development was noted. 



The results of a study of the frequency distribution of the 

 different types of flowers upon the plant point to the existence 

 of a definite region on the plant in which the tendency to vary 

 and proliferate is most pronounced. Considering the plant as 

 a whole, this region is confined to the basal, differentiated parts 

 of the plant. The first three branches on the main stem from 

 below, especially the second one, mark the seat of greatest ab- 

 normal development, while the 4th, 5th, and 6th branches show 

 a low degree of variability as well as the lowest absolute num- 

 ber of flowers. In the basal region of the terminal raceme the 

 output of flowers and the range of abnormality again increases. 

 Similar but more marked differences prevail in the individual 

 branches of the second and third order. Here, it is again the 

 buds in the axils of the second leaf and in the basal region of 

 the terminal raceme that show the greatest relative number of 

 abnormal flowers as well as the greatest range of variability as 

 measured by the frequency occurrence of the most aberrant 

 variants. 



Relative to the frequency occurrence of the different types 

 of flowers at different periods of the flowering season, under 

 the prevailing conditions, the first and second week of the 

 flowering season mark the lowest relative production of ab- 

 normal flowers, after which a marked increase in the output 

 of abnormalities follows when the secondary and tertiary 

 branches begin to develop their flowers. Towards the end of 

 the flowering season the upper regions of the plants produced 

 only very few flowers while the lower differentiated parts of 

 the plants sustained their flower production to the end of the 

 flowering season.
