Rumex confertus is an invasive plant to the flora of Bulgaria. The species is the only representative of Rumex, sect. Rumex, subsect. Conferti in Bulgaria. The information about the distribution of the species in the country is contradictory. The materials of R. confertus were wrongly determined as R. patientia, probably because the two species have similar morphological characteristics. Diagnostic morphological parameters and somatic chromosome number of the species 2n = 100 have been presented. This is the first chromosome number report from the Balkans. New chorological data of the species in the Bulgarian flora have been reported for the Znepole region. The Bulgarian distribution of the species has been mapped.
