It is further shown that the branching of the ramose variation, which 
would seem to represent a reversion to a more primitive form, does not 
approximate the branched inflorescence of teosinte, but is farther re¬ 
moved from teosinte than from normal maize. 
With respect to the correlations among the characters which dif¬ 
ferentiate maize and teosinte, but which are not involved in the change 
from normal maize to the three variations studied, there seems to be 
practically complete freedom of recombination within the limits of phy¬ 
siological relationships.
