The application of a new clustering technique, named "distance-ranked sorting assembling" (DRSA), for the classification of plant communities is considered. Aspects of the stability of a phytocoenotic classification are analyzed. It is shown that a researcher can vary the scale of clustering and thus change the number of phytocoenons, classify reasonably the data of a wide environmental amplitude, and determine objectively ecotonic releves among the data. We suggest to use the quantity of faithful species per phytocoenon for qualifying clusters in the field of geobotany.
