During the last fifty years a great deal has been said about the in 

 fluence of nutrition, vegetative vigor, etc., upon the development of 

 anomalies. If a larger number of rays indicates greater vigor or better 

 nutrition one might a priori expect larger inflorescences to have a pro 

 portionately higher number of branched rays, providing of course, that 

 the classic theories are true. 



The constants for a short series of data collected in 1906 were pub 

 lished in 1909. Since then a large number of determinations have been 

 made on a general sample of inflorescences from a number of shrubs in 

 1909 and from three large individual shrubs in 1913. 



In the latter series the data have been analyzed in two ways. First, the 

 inflorescences which contain at least a single abnormal pedicel have been 

 used as the basis of the correlations. These are designated as the ab 

 normal inflorescences. Second, the normal inflorescences from the 

 same plants have been included and counted as zero in the distribution 

 of number of abnormal rays. 

 The results are:

For 1909. Massed statistics. Inflorescences producing some abnor
