The Polygono brittingeri-Chenopodietum rubri includes open, but in some cases also closed stands of annual nitrophilous herbs, most frequently Persicaria lapathifolia, in warm areas also Xanthium albinum s. l. On many sites it contains different neophyte species. This vegetation type is most typical of alluvial sediment accumulations on the banks of large rivers, but it also occurs along smaller streams, in oxbows, and on the exposed bottoms of fishponds and water reservoirs. Substrate is usually sand or gravel with a good nutrient supply. This vegetation occurs across the whole Czech Republic except in high mountain areas; it is most frequent in lowlands and warm colline areas.
