phytosociology The classification of plant communities based on floristic rather than life-form or other considerations. The most renowned and extensively used phytosociological scheme is that developed by J.Braun-Blanquet (1927 and later) and his associates at Zurich and Montpellier. A similar, fairly widely applied scheme was developed by G. E.du Rietz (1921 and later) and others at Uppsala. These schemes are now being replaced by computer-based methods of quantitative phytosociology. See association analysis and ordination method.
