    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 relict tree species Zelkova abelicea and Z. sicula (Ulmaceae) occur in Crete and Sicily, respec- tively. Zelkova abelicea grows in approximately 40 localities in the mountains of Crete, while Z. sicula has been found in only two stands in Sicily. We compared 25 morphological characters of the leaves of both species and used statistical methods (Tuk- ey’s test, discrimination analysis, principal component analysis, agglomeration) to reveal the differences between these two species, their relation to Z. carpinifolia (the third Zelkova south-west Eurasian species), and between the leaves from different shoot types. Our study represents the first comparative biometric analysis of the three Zelkova species localized in the western edge of the current geographic range of the genus. We found that the species differed from each other both, in terms of leaf form characters and level of leaf variation. Zelkova carpinifolia was clearly differ- ent from Z. abelicea, while the two populations of Z. sicula, SIB and SIA, were more similar to Z. carpinifolia and Z. abelicea, respectively. The latter finding supports the results of recent molecular studies suggesting the hybrid origin of Z. sicula. Zelkova abelicea, Z. sicula and Z. carpinifolia differ each other in the leaf characteristics and level of phenotypic variation.

    Opis:
    The intra- and inter-population variation in three populations of Juniperus excelsa, two from Crimea and one from the Balkan Peninsula, were analyzed biometrically. Fourteen morphological characters of cones, seeds, shoots and leaves were used. The number of seeds per cone appears to be the most variable character. The others were more stable. Differences among particular individuals within the samples were slight, as well as between populations compared. The Crimean samples were very close to each other, while the more geographically distant sample from the Balkan Peninsula appears also to be morphologically more separate. This suggests that the Balkan populations originated from another Pleistocene refugium. The Crimean populations did not show the reduction of variability, which could have resulted from their geographical isolation and their considerably restricted numbers of individuals.

    The paper describes a new taxon: Pyrus × myloslavensis, i.e. a spontaneous hybrid between P. communis (Common Pear) and P. salicifolia (Willowleaf Pear), found near Miłosław town (Wielkopolska province, West Poland). No such hybrid has been reported in the literature so far. P. × myloslavensis has elliptic leaves, 1.1–7.6 cm long and 1.0–2.9 cm wide, margin entire, near the apex shallowly and remotely serrate, shortly acute, silvery tomentose on both sides. Fruit of the hybrid is relatively large (mean weight 56.2 g), green-yellow, without rust-coloured patches and blush.

    Opis:
    This paper presents the results of the study on morphological differentiation of seeds of five Polish species of the genus Sorbus L. (S. aria (L.) Crantz, S. aucuparia L. Emend. Hedl., S. chamaemespilus (L.) Crantz, S. intermedia (Ehrh.) Pers. and S. torminalis (L.) Crantz). The biometric data of 1980 seeds were subjected to multivariate statistical analysis in attempt to define intraspecific variation and to find differences between studied taxa. Most of the seed traits are significantly correlated and are characterised by moderate level of variation. Seeds of S. aucuparia (both subspecies) are the least variable while seeds of S. torminalis and S. intermedia the most. On the basis of size and shape traits of Sorbus seeds only seeds of S. aucuparia can be definitely distinguished from the others.

    Opis:
    Inter-simple sequence repeat (ISSR) amplification was used to analyze polymorphism of microsatellite sequences in the lilacs genom and to evaluate genetic diversity among seven lilacs species (Syringa × prestoniae McKelvey., S. reflexa K.C. Schneid., S. villosa Vahl, S. × chinensis Willd., S. meyeri K.C.Schneid., S. vulgaris L.and S. reticulata (Blume) var. amurensis (Rupr.)). The plant material was originated from the collection of Dendrological Garden in Przelewice.A total of 30 primers, containing different simple sequence repeat motifs were tested for amplification.Out of the 30 primers only 13 gave interpretable banding patterns in all lilacs species.A total of 182 ISSR fragments were generated with 13 primers of which 109 (60%) were polymorphic and 57 (31.2%) species-specific. ISSR–PCR with genomic DNAs of the showed lilacs yielded DNA fragmets ranging form 2200 to 123 bp in size.Species-specific ISSR fragments were detected for each lilacs accessions.UPGMA cluster analysis was used to construct a dendrogram and to estimate the genetic distances between lilacs species.The ISSR-based phylogeny was generally consistent with Syringa taxonomy based on morphological and phenological evidence.

    The Crimean taxon at issue has long been known as Stankiewicz pine with continuing discussion around its taxonomical rank and origin. In 1995, the authors discovered the new isolated population of the taxon on Papayakaya Mt. in Crimean Sub-Mediterranean. Due to hypothetical paleogeographic reconstruction ofPleistocene coastal landscapes here, together with some newest taxonomical data, authors reinforce the notion of relict and infraspecific status of the taxon that should be related to Pinus brutia var. pityusa.

    Opis:
    The variability of pollen grains of 16 species from genus Rosa L. was studied (i.e. Rosa agrestis, R. canina, R. dumalis, R. gallica, R. inodora, R. jundzillii, R. kostrakiewiczii, R. majalis, R. micrantha, R. mollis, R. pendulina, R. rubiginosa, R. sherardii, R. tomentosa, R. villosa, and R. zalana). The material came from 107 native localities of those species in Poland. The measurements are based on at least 30–50 randomly selected mature pollen grains per specimen. In total, 3510 pollen grains were examined. They were analysed for 8 quantitative features, i.e. length of polar axis (P), length of equatorial axis (E), exine thickness on the pole (Exp), exine thickness at the equator plane (Exe), length of ectocolpi (Le), P/E ratio, and relative thickness of exine (Exp/P and Exe/E ratio). Statistically significant differences were found among the examined species with regard to all analysed pollen features. The pollen and ectocolpi dimensions (P, E and Le) were largest in R.gallica (35.9, 28.1, and 28.0 μm, respectively) and smallest in R. majalis (27.0, 20.2, and 21.2 μm, respectively). The mean coefficients of variability of the pollen features measured can be used to arrange the examined rose species from the least to the most variable as follows: R. pendulina, R. villosa, R. jundzillii, R. inodora, R. canina, R. rubiginosa, R. dumalis, R. gallica, R. agrestis , R. micrantha, R. zalana, R. tomentosa, R. sherardii, R. majalis, R. kostrakiewiczii and R. mollis. The obtained data failed to confirm fully both the division of the Rosa genus currently in force in taxonomy into sections as well as relationships among the examined species from the Caninae section. In addition, values of morphological characters of the same species may differ considerably from one another. The extent of these differences indicated that it was necessary to measure large numbers of pollen grains in order to obtain accurate biometric data.

This paper describes the morphology of V. ×intermedium from Polish populations occurring in part of Pomeranian Lakeland in comparison with both parent species. The results presented here confirm the suggestions of earlier research that V. ×intermedium displays intermediate characteristics of leaf and floral morphology concordant with hybrid status. Also, is discussed the problem of the isolating mechanisms between parent species and hybrid's ecology.

The results of measurements were analysed statistically. The variation of the samples was generally not to large. Populations from the East Carpathians appeared different from all other examined. Two formed groups of analysed populations are separated mainly by thickness of epidermal cells, width/thickness of epidermal cell ratio, needle width and needle thickness. The differences between two groups of populations suggest their longer separation during Pleistocene.

    Opis:
    The putative hybrid character of two Tilia varieties selected as avenue trees (‘Szent Istvan’ and‘K3’) should be clarified for further breeding activities. Their ancestor species should be identified by a genetic comparison with reference material (Tilia cordata, T. platyphyllos, T. dasystyla, T. × euchlora, T. × europaea and others). RAPD marker data were evaluated by UPGMA cluster and neighbour-joining analysis. The genetic comparison of the two selected clones with the collection of reference material offers insights into some systematic relationships within the genus Tilia. It was supplemented by a critical discussion of methods of RAPD data evaluation for taxonomic purposes.

    Opis:
    Semenov’s Fir (Abies semenovii B. Fedtsch.) is an extremely rare species in the wild and is included in the International Red List of Conifers and into the Red Data Books of the former USSR and Kyrgyz Republic. Our investigation confirms that this is an independent species, related but not identical to Abies sibirica Ledeb. It has been cultivated at Peter the Great Botanic Garden of the Komarov Botanical Institute of the Russian Academy of Science(s), St.Petersburg, since 1949. Apparently, it was here that Semenov’s Fir was first introduced into cultivation in European gardens. It has produced seeds since 2000, when it was less than 43 years old. It is a hardy and ornamental tree that deserves wider distribution in cultivation in the gardens and parks of North-West Russia. It is proposed that Semenov’s Fir should be given independent taxonomic status as a separate species, Abies semenovii B. Fedtsch.

    Opis:
    Oaks are classified heavily based on the leaf morphology. However, identification of specimens without acorns is usually controversial in Cerris section. Although members of Cerris section have a broad distribution area, there are only few taxonomic studies. Therefore, the current study is the first to show the discrimination of species in Cerris section based on leaf characters from Turkey. Discrimination among the members of Cerris section over Turkey (Q. cerris L. var. cerris, Q. ithaburensis Decne. subsp. macrolepis (Kotschy) Hedge and Yalt, Q. brantii Lindley, Q. libani Olivier, and Q. trojana P. B. subsp. trojana.) was aimed and variations within and among the species based on 15 qualitative leaf characters was presented. In this work we have studied the natural variability of these species by analysing leaf materials collected from 44 populations around Turkey. Cluster Analysis (CA) and Principal Component Analysis (PCA) were performed to assess intra-specific differentiation and to compare the distribution of variance in the individual and population level. The results showed that the leaf characters presented a good discrimination of five Cerris taxa in PCA at the population level, but the relationships between Q. ithaburensis subsp. macrolepis and Q. brantii showed complex groups in CA. Among the studied taxa, the highest variation was found within Q. cerris populations. In this work, we obtained discrimination of Cerris section species from Turkey based on leaf characters which is quite useful for those herbarium specimens without acorns and in other systematic observations.
