The paper contains our own data and observations issued from the scientifical papers, published between 1970 and 2020. Although, at a first approach, the flora of wet zones in the Romanian Banat region does not seem spectacular, our analysis shows the presence of several hundreds of species. In the past 50 years, many authors have studied these wet zones habitats bringing important contributions (floristic inventories, the study of rare or invasive species, general observations on the flora). Compared to the first part of the reference period, many species, considered common in the past, have become less frequent, some of them with uncertain spontaneous presence or extinct from the Romanian Banat: Hippuris vulgaris, Ludwigia palustris, Stratiotes aloides, Hottonia palustris, Lysimachia punctata, Potamogeton lucens, Zannichellia palustris, Marsilea quadrifolia. Significant changes are also noticed in cormoflora structure in terms of life forms and geo-elements. Reducing and degrading habitats and direct human pressures, the presence of invasive species (Amorpha fruticosa, Echinocystis lobata, Reynoutria japonica, Helianthus tuberosus, Asclepias syriaca, Lindernia dubia) are serious threats to wet zones cormoflora, including that of the protected areas.
