Siberian stone pine (Pinus sibirica) and Siberian dwarf pine (P. pumila) are widespread in northern Asiafive-needle pines from subgenus Strobus. The natural hybridization occurs in many regions where the species growtogether. Traditional hybrid zone model was considered in the paper and, based on the accumulated data, it is determinedwhich one corresponds to the hybrid zone of Siberian stone pine and Siberian dwarf pine. The paper presents argumentsin favor of the mosaic model.
