Abstract
In 1928 Braun-Blanquet and Pavillard (1) published the "Vocabulaire de Sociologie Végétale," in which an attempt was made to define and standardize the various current concepts relating to descriptive phytosociology. Since the continental concepts vary somewhat from those of American workers, the terminology differs slightly. The terms relating to the organization of any plant community are, according to them, arranged in a sociological "Reléve" or floristic enumeration in which each species of plant is given with the coefficient or number corresponding to the class to which it belongs in the analytical or synthetic concepts.
