Hybridization among Pinus mugo and P.sylvestris is visualized in Wells' distance diagrams using either equally or differently weighted characters. Parents and hybrids are better resolved in diagrams using differently weighted characters. Putative hybrids from mixed, planted or naturalized stands of P. mugo and P. sylvestris in SW and NW Jutland, Denmark, are compared with artificial F 1 and spontaneous material of P. mugo × sylvestris (P. × rhaetica ) from the Alps and the Pyrenees. The natural hybrids are primary hybrids, rather than introgressants.
