Includes stands of Carex spp., Cladium mariscus, Equisetum fluviatile, Glyceria maxima, Hippuris vulgaris, Phragmites australis, Sagittaria sagittifolia, Schoenoplectus spp., Sparganium spp. and Typha spp. Excludes terrestrialized reed and sedge beds which are not at the water's edge (D5.1, D5.2).

Communities of the margins of shallow lakes, rivers and brooks dominated by shorter, mostly non-graminoid helophytes emerging from mesotrophic or eutrophic, stagnant or slow-moving, shallow water, and constituting fringes or patches within or alongside reedbeds. Habitat structure is determined by one or two dominant species, e.g. Alisma spp., Oenanthe aquatica, Rorippa amphibia, Sparganium spp., Sagittaria sagittifolia, Equisetum fluviatile, Acorus calamus and Hippuris vulgaris (see subdivisions).
