The genus <i>Rubus</i> in South Africa. I. Chromosome numbers and geographical distribution of species

The geographical distribution of 14 of the Rubus species in South Africa is presented. Chromosome numbers of nine of the species were determined: six for the first time, one is confirmed and additional polyploid levels are described for the other two species. It is demonstrated that the South Afri...

It is demonstrated that the South African species of the subgenus Idaeobatus contain less diploid specimens and more polyploid specimens than their extra-African counterparts. This phenomenon could be attributed to hybridization between the subgenera Eubatus and  Idaeobatus.https://abcjournal.org/index.php/abc/article/view/1853chromosome numbersgeographicadistributionhybridizationpolyploidy<i>Rubus</i>
