Rubus vikensis A. Pedersen ex G. Wendt (sect. Corylifolii ) was recently described from a restricted area in north western Scania, Sweden. In this investigation, I show that the same species occurs also on the Onsala peninsula in northern Halland and on a single locality in the middle of Halland. It has 35 chromosomes in all parts of the distribution area. Moreover, I show by random amplified polymorphic DNA (RAPD) analysis that R. vikensis is a distinct and well‐defined species, clearly separated from the morphologically similar R. wahlbergii , with which it shares the chromosome number.
