| | Résumé : | "We present a structure of the Pilosella populations occurring in the Krkonose Mts, northern Czech Republic. Each basic species, hybridogenous species and recent hybrid is documented by its frequency, cytotypes, breeding system, and chloroplast haplotypes. We compare this structure with the situation in another mountain range, the Sumava Mts in the south western Czech Republic. Both regions have the same structure ofhybridising species, but the resulting population are different. We de duce that random phenomena in the past and the residual sexuality of apomictic species has influenced the present population composition. Our results are discussed in connection with existing approaches to the taxonomy of Pilosella."
