• Electrophoretic data were used to assess levels of clonal diversity within and among populations of Taraxacum albidum Dahlst., a pentaploid obligate agamosperm indigenous to Japan. All specimens sampled from the entire distribution range shared the same 19-locus genotypic profile except for one. This single mutant differed in one allele at one locus only. Contrary to this extreme monomorphism, clonally reproducing species usually consist of multiclonal populations. It is hypothesized that T. albidum recently originated through hybridization between a sexual diploid species of the section Mongolica (most likely T. japonicum Koidz.) and an unknown polyploid Mongolica species.
