Pinus mugo complex (Pinaceae) – taxonomic relations based on needle characters. Fragmenta Floristica et Geobotanica Polonica 11(2): 235–255. Kraków. PL ISSN 1640-629X. ABSTRACT: The relations between Pinus mugo, P. uncinata and P. uliginosa [=P. ×rotundata], which form Pinus mugo complex, were examined biometrically on the basis of morphologic and anatomic characters of needles. All these taxa are statistically significantly different in respect of most of the 15 characters studied from compared P. sylvestris. In spite of close relations among P. mugo, P. uncinata and P. uliginosa, several morphologic and anatomic characters of needles discriminated them statistically significantly. The results suggest that P. mugo and P. uncinata should be treated as independent species, not as subspecies of P. mugo sensu lato. The intermediate position of P. uliginosa between two latter taxa suggests its hybrid origin.
