Abstract
In this arcticle anomalies of prolification and «ramification» in the inflorescence of genus Typha are examined. It is noted that during all periods of the Cenozoic era the type of the genus was a complex ear (of different sexes) in the common inflorescence axis. Appearance in the inflorescence Typhaceae of the anomalies of prolification and «ramification» is connected with strengthening of anthropogenic factor. These processes can be interpreted as the tendencies of the extinction of the initial «parental» form of inflorescence, in connection with the formation of new structure.
