Raycheva Tz. 2011. Rumex confertus (Polygonaceae) in the Bulgarian flora. Botanica Serbica, 35(1): 55-39.

Abstract: Rumex confertus is an invasive plant to the l ora 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.

Key words: Bulgarian flora, chorology, chromosome number, map, Rumex confertus, morphology.

Rumex confertus je invazivna biljka u flori Bugarske. Ova vrsta je jedini predstavnik roda Rumex, sect. Rumex, subsect. Conferti u Bugarskoj. Podaci o rasprostranjenju ove vrste u Bugarskoj su kontradiktorni. Materijal R. confertus je pogresno odredjivan kao R. patientia, najverovatnije prema slicnim morfoloskim karakteristikama. U radu se navode dijagnosticni morfoloski parametri i broj somatskih hromozoma ove vrste 2n = 100. Ovo je ujedno I prvi put utvrdjeni broj hromozoma kod ove vrste sa Balkana. Novi horoloski podaci o ovoj vrsti u l ori Bugarske navode se za oblast Znepole. Mapirana je distribucija ove vrste u Bugarskoj.
Kljucne reci: Flora Bugarske, horologija, broj hromozoma, mapa, Rumex confertus, morfologija.
