Abstract
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.
Abstract (in Czech)
Analyzovali jsme status dvou východokarpatských (rumunských) populací rodu Cochlearia v kontrastu se dvěma západokarpatskými druhy tohoto rodu, diploidním C. pyrenaica (2n=12; 2C=0.78pg) a hexaploidním C. tatrae (2n=42; 2C=2.09 pg). Vzhledem k rozdílům v morfologii, 2n=48 a obsahu DNA, 2.82pg, navrhujeme považovat východokarpatské (rumunské) populace za samostatný druh, C. borzaeana (Coman et Nyár.) Pobed. Lektotypus byl vybrán. Nová subasociace Carici flavae-Cratoneuretum Kovács et Felföldy 1958 cochlearietosum borzeanae je popsána. Izolovaná populace C. pyrenaica s.l. z Ukrajiny (2n=2x=12; 2C=0.91 pg) byla rovněž studována, vzhledem k její nejasné taxonomické pozici. Diploidní počet chromosomů 2n=2x=12, byl zjištěn u této izolované populace C. pyrenaica s.l. na Ukrajině. Avšak značný rozdíl ve velikosti genomu odlišuje tuto populaci od západokarpatských.
