Abstract
The anomaly of branchiness type is consideed, which is a separation of floral receptacle in the pistillate part of the inflorescences of Typha grossheimii of hydrophilic genus Typha (Typhaceae). It was established on the basis of the analysis of pistillate flowers that spontaneous expansion of the range of T. pontica is detected in the disturbed habitat of the Kagalnik river (Rostov Region), in connection with intensification of the anthropogenic factor. This fact may be a sign of technogenesis, resulting in the phenomena of this kind. At the same time, this is an interesting attribute of transformation process, i.e. selective destruction or substitution of so-called ancient (Sarmatian) species by new technogenic structures.
