This vegetation type, dominated by Myriophyllum verticillatum, a submerged species, occurs in mesotrophic to naturally eutrophic, clear water, e.g. in oxbows and other types of alluvial pools, small fishponds, channels and lentic sections of streams. In contrast to stands of M. spicatum, it occurs in habitats in an advanced stage of terrestrialization, while it is absent in recently established, and rare in man-made water bodies. It is an uncommon vegetation type in the Czech Republic.
