organs. For this purpose it will be necessary to tabulate the results in series and 
consequently it might be well to start with the outermost constituent of the flower, 
namely, the outer whorl of the calyx, and tabulate the correlation coefficients 
passing inwards to the androecium. The inner whorl of the calyx will next be 
taken in relation to the other constituents and so on. 
From the above table it will be seen that the outer whorl of the calyx is most 
highly correlated with the corolla ; it is also highly correlated with the outer whorl 
of the androecium but much less so with the inner whorl of the androecium.

The low correlation between the inner whorl of the calyx and the corolla is due 
to the close adherence of the former to type, that is, there is very small variability.

There is a higher degree of correlation between the two organs of the perianth 
than between the calyx and the andrcecium. The high correlation between the 
calyx and the outer whorl of the androecium is mainly due to the high value 
obtained for the correlation between the outer whorl of the calyx and the outer 
whorl of the androecium.
