The aim of the present study was to compare biometrically three distant populations of Juniperus oxycedrus subsp. macrocarpa on the basis of the characters of cones, seeds and needles. The shortest Euclidean distances were used in the agglomerative grouping of closest neighbourhood and discrimination analysis with principal component analysis was performed to verify the south-north differentiation of the taxon in Italy. Cone lenght as well as seed number, width and thickness were significantly correlated with geographic latitude, while the other four characters are not
