HARRIS—THE INFLORESCENCE OF MANFREDA VIRGINICA 429 
The investigation of this question has its obvious bearing on 
the problem of periodicity. Periodicity is the term used by de 
Vries and other biologists to express the idea that the form or 
size of the organs produced laterally along an axis is to some 
extent correlated with their position in such а manner that as 
one passes from the proximal to the distal region of the axis there 
is at first an increase to а maximum and then a decrease of the 
value of the character of the laterally produced organ.
