The range of variation of the above flower characters is shown by the 

 follo\\'ing figures based on one thousand flowers : — 



(a) Length oj 'petals. 

 Millimetera Frequency 



Here again we have a very wide variation and clear illustrations of a 

 mixture of strains with different lengths of petals. The mean length is 18'6 

 millimeters, but with such a mixture of strains the mean ceases to have much 

 value. The interesting figures would be the correlation between the length 

 of the petals and of the bracteoles, and this will be determined in a further 

 study of this question. A curve embodying the above figures is shown below 

 (Figs. 6 and 7).
