Correlation of Variation 

 Cal7/x 



In every case of calyx variation, whether above or below the 

 mean, all the other whorls are above the average. As there are, 

 however, only 41 specimens out of the 1000 to prove this, I do 

 not think that much importance should be attached to the results.

Calyx and Corolla 

 Analysis of variation in calyx and corolla — 



The calyx having practically no variation, it appears from the 

 above that if there is any superabundant calyx- or corolla-material 

 in the embryonic flower, rather than increase the two whorls alike, 

 the sepals are left imaffected, and the superabundant matter goes to 

 form more petals — third line of above table. Actually, the calyx 

 and corolla whorls of the specimens represented in that line have a
