| Description | We analyse the status of two East Carpathian (Romanian) Cochlearia populations by comparing them with the two native species from the Western Carpathians, the diploid C. pyrenaica (2n=12; 2C=0.78pg) and hexaploid C. tatrae (2n=42; 2C=2.09 pg). Because of differences in morphology, 2n=48 and DNA content, 2.82pg, we propose the East Carpathian (Romanian) populations as a separate species, C. borzaeana (Coman et Nyár.) Pobed. The lectotype is designated. The new subassociation Carici flavae-Cratoneuretum Kovács et Felföldy 1958 cochlearietosum borzeanae is described. An isolated population of C. pyrenaica s.l. from Ukraine (2n=2x=12; 2C=0.91 pg) has been also studied, because of its unclear taxonomic position. The diploid chromosome number, 2n=2x=12, is given for this single known population of C. pyrenaica s.l. in Ukraine. However, there is considerable difference in genome size and chromosome size between West Carpathian C.pyrenaica s.s. and Ukrainian plants. |
