Our mathematical-statistical approach to the classification of character elements is
based on Vavilov's Law of Homologous Series. Character elements are formally expressed as
frequency values of Integral Parameter in the Compression Mapping System (IPCMS).
Consistent general patterns of IPCMS numerical values are revealed. Characteristics of each set
of values depict infraspecific variability caused by variation of environmental conditions
affecting representatives of a certain species. Upon sequential ordering of the coefficient mean
values, species-specific changes in the distribution of frequencies are revealed. The potential of
this method for studying infra- and inter-specific variability in phenotypic characters is
demonstrated using an example of three taxa within Agropyron, wheatgrass.
