Abstract
The Scandinavian endemic plant Saxifraga osloensis is believed to be an allotetraploid derived from the diploids S. adscendens and S. tridactylites. We used gel electrophoresis of enzymes to characterize the genetic constitution of the three species. The results support both the allotetraploid nature of S. osloensis and its ancestry from the two assumed parental species. The pattern of genetic differences among local populations of the three species indicates that S. osloensis has arisen from hybridization in the western part of its present distribution area, possibly at a single occasion.Keywords
