    Opis:
    Two-year needles were collected from 42 trees from 5 localities in Spanish Pyrenees. The needles were analysed in respect to 15 morphological and anatomical traits. Data obtained were subject of multivariate statistical analyses. The most stable traits appear to be width of epidermis cells, width and thickness of the needles and ratio of the last two characters. Number of the resin canals and the vascular bundles distance were the most variable characters. The differences among the 42 investigated trees are not evident, considerably small and not significant statistically.
    Praca zawiera szczegółową analizę zmienności igieł P. uncinata. Materiał pochodził z 5 różnych naturalnych stanowisk z 42 drzew z hiszpańskich Pirenejów. W badaniach uwzględniono 15 cech morfologicznych i anatomicznych a uzyskane wyniki z pomiarów poddano szczegółowej analizie statystycznej. Ustalono, że zmienność między drzewami w badanej populacji P. uncinata jest stosunkowo niewielka i nie istotna statystycznie. Najbardziej stabilnymi cechami okazały się iloraz grubości i szerokości igły (cecha14), szerokość komórek epidermy (cecha11), szerokość i grubość igły (cechy 7 i 8) a także grubość komórek epidermy (cecha 10) i liczba szparek po obydwu stronach igły (cechy 4 i 5). Współczynniki zmienności dlawspomnia nych cech nie przekraczają 9%. Największe różnice, jednak statystycznie nie istotne, obserwowano w liczbie kanałów żywicznych (cecha 6) i w odległościach między wiązkami (cecha 9) oraz we współczynniku Marceta (cecha12).

    Opis:
    Pollen grains of Pinus uliginosa and P. uncinata were examined by light and scanning electron microscopy. The pollen grains were bisaccate and monosulcate. The corpus-saccus attachment was distinct. The pollen corpus exine sculpture was verrucate-rugulate and deeply sculptured. The surface of the tectum was with or without small grana and it was perforate. The saccus sexine ornamentation was reticulate and irregularly perforate. The tectum surface characters in the proximal and distal view of the corpus and saccus were less variable and they did not provide good criteria to identify the species under study. Among the P. uncinata from the Forest Arboretum there were differences observed in the size, shape and height of elevation and sculpture on the corpus between pollen grains of the same specimen. This study of the pollen grain morphology of the corpus and saccus provided some important new data.

    Opis:
    The frequency of occurrence of abnormal, three- (or more) needle dwarf shoots of most southern and central European two-needle pine (Pinus) species were studied. No specimens with more than two-needle dwarf shoots were found in a population of P. nigra Arnold subsp. salzmannii (Dunal) Franco from the Iberian Peninsula and in two populations of P. uliginosa Neumann from the Sudeten Mountains in Central Europe. Single specimens were found within one population of P. pinaster Aiton from the Iberian Peninsula and among six populations of P. sylvestris L. from the Iberian Peninsula and Central Europe. Abnormal dwarf shoots mostly with three, but also four, five or six needles were found among 24 of 25 surveyed populations of P. mugo Turra and P. uncinata Ramond. The average frequency of specimens with at least one three-needle dwarf shoot was 24% for P. mugo and 20% for P. uncinata. The frequencies of occurrence varied significantly among studied populations and were highest in samples collected from the upper elevational range limits of the species in the mountains and near the northern limits of their ranges. The frequency of abnormal dwarf shoots in the same populations was significantly high in 2-3 consecutive years. Needles from three-needle dwarf shoots were not significantly shorter than those of two-needle shoots.

    Opis:
    The characteristic of Pinus uncinata on the basis of biometrical analyses of 16 cone features was done. The research was based on 8 samples representing 6 populations, consisting of 50 cones each, collected in the Pyrenees, within the natural range of the species. All the investigated cone features were moderately differentiated, with the variation coefficient ranging from 8 to 30%. The particular populations differ significantly from each other statistically according to several features examined. The samples collected in the same population also vary significantly. The differences between populations, however, do not enable their division into groups, which supports their origination from the same Pleistocene refugia.

    Opis:
    The taxonomic position of the population of tree-like, mostly polycormic individuals of pines from the Mshana peat bog in the Gorgany Mountains (East Carpathians, Ukraine) has been studied on the basis of the morphological characteristics of cones and needles, and anatomical characteristics of the needles. These features have been compared with the surrounding Pinus mugo population as well as P. uliginosa, P. mugo, P. sylvestris and P. uncinata from natural populations of the taxa. Tree-like individuals were found to have the most similar needles to P. uliginosa, but most similar cone characteristics to P. mugo. It was concluded, that the tree-like population has a relic character and can present the trace of the early migration of P. uliginosa from the West and its hybridisation with P. mugo.
