  Forests of the Tisza floodplain in the northwestern part of Hungary include white willow riparian forests (Leucojo aestivi-Salicetum albae) that are phytosociologically little studied. This study summarizes the characteristics of this community based on 25 phytosociological relevés. These forests grow mostly on mud and raw alluvial soil in the low-lying parts of the lower terraces of the floodplain. They are easily separated by their species composition and underdeveloped shrub layer from white poplar gallery forests (Senecioni sarracenici-Populetum albae)., which grow on higher lying ground with rather light sandy soil and typically possess a pronounced shrub layer. The understory of their stands may often host plants  that are rare or completely absent in other parts of the country, such as Cardamine amara, Cardamine flexuosa, Cardaminopsis arenosa, Carex pseudocyperus, Carex remota, Chrysosplenium alternifolium, Leucanthemella serotina, Leucojum aestivum, Oenanthe banatica, Scrophularia scopolii, Telekia speciosa, Vitis sylvestris. This community is classified in the „Salicenion albae-fragilis Kevey 2008” suballiance.
