Juniperus oxycedrus subspecies macrocarpa belongs to the section Oxycedrus of the genus
Juniperus. It occurs on dunes or maritime rocks along the Mediterranean coast and sometimes
forms groves, as for example In Italy, Spain,Greece, Tunisia and Marocco.
The intra- and interpopulational geographic variation of four distant populations of Jniperus
oxycedrus subsp. macrocarpa was the aim of the present work. Populations were examined
biometrically on the basis of morphological characters of needles, stomata, cones and seeds.
Four populations of J. oxycedrus subsp. macrocarpa from Italy, Greece, Turkey and Spain
were examinnated on the basis of characters of 10 needles and 10 cones from mostly 30
individuals from each population. Results of the discriminating analysis and the cluster
analysis showed that population from Turkey and Crete in Greece are morphologically most
close to each other. The most different from all the other appeared is population from Spain
which is also the most distant. The separation by distance can be a reason of these differences.
