1920 F. E. Clements Plant Indicators 276 The grouping of consociations within the association is typical of all climaxes, and seems to warrant a special term... It has seemed desirable to definitize the term facies for seral groupings and to make a new word, faciation, for climax groupings... The two terms conform to the mutual relation seen in associes and association, consocies and consociation.
