Spontaneously dispersing vascular plants of protected ground with limited migration

Floristic diversity, locality and reproduction characters of spontaneously dispersing vascular plants of protected ground with limited migration were studied in the separate greenhouses and phytotron of the Main botanical garden, Russian Academy of Sciences (Moscow). These species have limited spontaneous dispersal within 1 -2 greenhouses with tropical or subtropical climatic pattern and do not grow on all substrates. A total of 21 taxa of such terrestrial vascular plants were identified, belonging to 16 genera from 13 families. Some of them - 11 species are representatives of systematic collections that «escape» from pots. The remaining 10 species were previously specially planted as ornamental plants, and spontaneously grew nearby. Several identified species have the potential to become more widespread in the future, so effective methods of phytosanitary control are needed.
