P. uncinata appears the most distant from all other taxa, differing by having the largest and most asymmetric cones and the thickest apophyses with the most prominent umbo. In cone characters, P. mugo is more similar to P. sylvestris than to P. uncinata. Nevertheless, P. mugo and P. sylvestris remain distant from each other in a number of morphological characters examined. P. uliginosa has cones intermediate between the other three taxa and is moreover very variable. The locality of P. uliginosa in the Silesian Lowland may be of a relict character and conserve genes from P. uncinata.

Cluster analysis of Euclidean distances and discriminant analysis were performed to verify the hypothesis of geographic differentiation and origin from the West- and East-Mediterranean Pleistocene refugial regions. The West-Mediterranean populations of J. oxycedrus subsp. oxycedrus differed from the eastern ones. The intra-populational differentiation of three of the West-Mediterranean populations was significantly higher than within the other West- and all the East-Mediterranean ones.Results confirm the hypothesis of probable different origins of the East- and West-Mediterranean populations of the taxon.
