250 Contribution to a Statistical Study of the Cruciferce 
The corolla is much more highly correlated with the outer whorl than with 
the innei' whorl of the androecium, and the correlation between the corolla and the 
androecium as a whole is not very great. 
A comparison of Tables T and U shows that there is a much greater correlation 
between the calyx and the androecium and its two whorls, than between the corolla 
and the same constituents. 
So far we have considered the relationships between the different parts of the 
flower from the outside inwards, but when we examine these relationships, taking 
the inner whorls as our starting point, some new aspects of* the problem become 
manifest and, as these have been of great value in the interpretation of the results, 
it has been considered advisable to tabulate them thus :

A comparison of Tables V and W shows that the correlations between the 
outer whorl of the androecium and the other components are higher than for the 
inner whorl of the androecium, except in the case of the inner whorl of the 
calyx.
