B. Number of Ovules per Pod. 



The nature of this and the following character has been 

 discussed elsewhere. 2 There the data from which all the 

 physical constants necessary in this study may be de- 

 duced, but not the constants themselves, are set forth. 

 Tables IX XI give these constants based on countings 

 of ovules formed and seeds matured in 130,074 pods. 



That the starvation of the individual affects not merely 

 the number of pods which it produces but the character- 

 istics of these pods as well is evident from a study of 

 these tables, but is best brought out by a special kind of 

 graph. 



Reducing absolute to relative frequencies, we take the 

 difference 



Starved less fed 

 for each ovule grade. Such differences are shown in 

 Diagram 8 for NDD-NDH, NDDC-NDHC, NHD-NHH, 

 NHDC-NHHC, USD-USE, USDC-USEC, FSD-FSH 

 and FSDC-FSHC. The differences for the ancestral 

 series, which for the moment alone interest us, are shown
