Abstract

Plant communities of the alliance Chenopodion rubri (Tx. in Poli et J. Tx. 1960) Hilbig et Jage 1972 (Bidentetalia tripartitae Br.-Bl. et Tx. ex Klika et Hadač 1944, Bidentetea tripartitae Tx. et al. ex von Rochow 1951) have not been studied in Siberia. The article presents an original diagnosis of the West Siberian association Rorippetum dogadovae-palustris Taran ass. nov. (Chenopodion rubri). The association has been studied in natural ecotopes on the banks of the Ob River at the southern boundary of the southern taiga subzone. The diagnostic species (d.s.) of the association are Rorippa dogadovae and Chenopodium acerifolium. The association includes two subassociations: Rorippetum dogadovae-palustris typicum and R. d.-p. sonchetosum arvensis Taran subass. nov. (d.s.: Sonchus arvensis, Poa palustris). In the stands of the R. d.-p. typicum subassociation, Rorippa palustris and Rorippa dogadovae predominate, the average species richness is 26 species per relevé, and the average relevé area is 17 m2. In the stands of the R. d.-p. sonchetosum arvensis subassociation, Rorippa palustris and Chenopodium rubrum predominate, the average number of species is 43 species per relevé, and the average relevé area is 18 m2. The originality of the Rorippetum dogadovae-palustris association is demonstrated by comparing it with the previously described associations of the Chenopodion rubri alliance. The probable range of the Rorippetum dogadovae-palustris association is south taiga and subtaiga sections of the Ob River floodplain. Ukrainian sorrel (Rumex ucranicus) is accepted as a regional differential species of the West Siberian communities of the Chenopodion rubri alliance
