Abstract

Three taxa belonging to the genus Hyoseris L. are compared from the caryologica! point of view. H. i-adiaia L. and H. scabra L. are regarded as "good species", whereas the taxonomic status of H. lucida L. is doubtful. This study is carried out on several populations collected in North Africa and the Iberian peninsula. Karyotypic differences occur in the morphology of chromosomes and in their banding patterns with the fluorochromes Chromomycin A, and Hoechst 33258, which settle on DNA rich in GC and AT bases respectively. Chromosome morphology differentiates H. scabra from both other taxa, which can be distinguished from each other by the number of GC-rich centromeric bands. The length of the heterochrornatic part of chromosome pair 3 displays a variation within H. scabra. Ribosomal RNA genes are located by in situ hybridization on chromosome pair 3 in H. scabra and provide additional evolutionary markers.
