“…All other analysed characters showed no differences between the compared populations ( Table 2). In the Sudetes, needle length and width, number of stomata rows on the flat (adaxial) side of the needle, needle thickness, distance between vascular bundles, thickness of epidermal cells, stomatal rows ratio, needle thickness/width ratio, epidermis cell width/thickness ratio and percentages of all types of sclerenchyma cells around the resin canals and between vascular bundles (character 1, 7, 3, 8, 9, 10, 16, 18, 20 and 21A, 21B, respectively) also revealed statistically significant differences between P. mugo and P. uliginosa Boratyñska and Boratyñski 2007;Boratyñska and Lewandowska 2009). This indicates a higher level of similarity between tree-like pines and shrub of P. mugo from the Mshana peat bog, than of P. uliginosa and P. mugo in the Sudetes.…”

“…Several characters of needles of tree-like individuals from the Gorgany Mountains have values typical for P. uliginosa, intermediate values of the character among all three compared populations of the latter species or are close to one of them (compare Table 2 and data from Boratyñska et al 2003;Boratyñska and Boratyñski 2007;Boratyñska and Lewandowska 2009). The length, width and thickness of needles and distance between vascular bundles (characters 1, 7, 8 and 9, respectively) have values intermediate among the three populations of peat bog pine, which can be treated as typical for P. uliginosa.…”

“…The aims of this study were: 1) to verify the influence of the tree-like versus shrubby growth form to the morphological characteristics of cones and morphological and anatomical characteristics of needles; and 2) to test the taxonomic status of the tree-like specimens of mountain pine from the Mshana peat bog using the morphological characteristics of the cones and morphological and anatomical characteristics of the needles (Szweykowski 1969;Staszkiewicz and Tyszkiewicz 1972;Boratyñska and Bobowicz 2000;Boratyñska and Boratyñski 2007;Marcysiak and Boratyñski 2007;Boratyñska and Lewandowska 2009).…”

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.

The main aim of the present study was testing the value of the morphological and anatomical characteristics of the needles in distinguishing Cedrus atlantica, C. libani and C. brevifolia. Nine populations were sampled in their natural habit and 25 characters were used to describe the variation of the brachyblast needles and to analyze the differences between species. The results indicated that morphological and anatomical needle characters provide valuable tools in discrimination of the taxa. The scored differences were statistically significant, as revealed in the Tukey's t test, discrimination analysis and hierarchical analysis of variation. The results support treating C. libani, C. atlantica and C. brevifolia as independent species.

In this study, range-wide genetic variation was analysed in 553 Pinus mugo Turra (dwarf mountain pine) individuals from 21 locations using 11 chloroplast microsatellites. Our main goal was to assess the spatial distribution of neutral genetic variation. We also used data from a previous study on the morphological variation of needles from 18 stands of P. mugo. In total, 22 needle characteristics were reanalysed and compared to microsatellite data to describe the distribution of morphological variation in the context of neutral genetic variation. We hypothesised that the chloroplast microsatellite and needle trait variation patterns would not entirely overlap. The results indicate the recent divergence of P. mugo populations derived from a formerly larger distribution. We identified 4 genetic and 3 morphological clusters whose spatial distribution overlapped only to some extent. The distribution of genetic variation showed a south-north pattern with signs of admixture in the Alps and Carpathians. Two south-westernmost stands from Italy were evidently isolated from the others. In contrast, morphological variation tended to display a west-east pattern. A separate group based on needle traits was formed mostly by eastern stands and was not observed by microsatellite analysis. In addition, a few needle characteristics significantly correlated with longitude and climate variables. These findings suggest that eastern populations of P. mugo may be of different origin and/or that some needle characteristics may be adaptively important in these locations. The potential roles of past demographic events, phenotypic plasticity and local adaptation in shaping the patterns of genetic and morphological variation in P. mugo are discussed.
