Abstract

Several taxa considered by previous authors as intraspecific of Potentilla taurica s.l. are considered as separate species. A diploid chromosome number 2n = 14 and the characteristic chromosomes of karyotypes of 3 Balkan endemics P. niĉiĉi Adam., P. emilipopii Nyarády and P. pirotensis (Borb.) Mark. are recorded. P. bornmuelleri Borb., P. mollicrinis (Borb.) Stankov and P. astracanica Jacq. are widespread in South-eastern Europe. Of this group P. mollicrinis is a diploid (2n = 14), P. bornmuelleri is tetraploid and in P. astracanica a polyploid serie of 2x = 14, 4x = 28, 5 × = 35 and 6x = 42 has been found. The karyotypes of all species are characterized by submetacentric chromosomes.
