Periodicity is also well marked here in tbe leaf-breadth frequency. So 
from these researches it seems that the fluctuating variability, which has 
revealed itself to us as a quality of the plant, behaves indeed quite like 
other quantitative properties, as concern periodicity during the successive 
development of the plant.
