    Opis:
    The paper presents the results of a study on mericarps and seed morphology of four taxa occurring in Poland: Heracleum sphondylium subsp. sphondylium and subsp. sibiricum, H. mantegazzianum and H. sosnowskyi. Apart from selected biometric traits we analysed pericarps and seed-coat patterns using a stereoscopic microscope (SM) and a scanning microscope (SEM). Considerable diff erences in the dorsal surface of mericarps were observed, but major structural similarities were found on the ventral surface of mericarps. Pericarp surface diff ers signifi cantly between native and alien taxa in terms of secondary sculpture. The examined seeds were characterised by reticulate primary sculpture with diff erent size and shape of testa cells. The macro- and micromorphological characteristics of the mericarp and seeds may provide valuable additional diagnostic criteria for delimitation of Heracleum and can be used in the identifi cation of fruits and seeds.

    Opis:
    The aim of this study was to investigate seed morphology and intra- and inter-population variation of seeds of Trollius europaeus L. and Trollius altissimus Crantz., two controversial species regarding their taxonomical position. We analyzed seed-coat microsculpture and some biometrical traits (length and width, width/length ratio, volume and projected perimeter). Seed sculpture did not differ between species, but seeds of T. altissimus were usually larger than seeds of T. europaeus. Although species differed significantly in seed morphology, it was possible to show the populations of both species that were similar regarding the analyzed seed traits. We noted a significant inter-population differentiation of seeds in both species with respect to seed-coat microornamentation and biometrical traits. We conclude that T. europaeus and T. altissimus are probably not two distinct species, but T. europaeus should be divided into two lower taxa in the rank of variety or subspecies.

    Opis:
    Pinus heldreichii (Bosnian pine) is a Balkan-Apennine endemic and relict pine species that inhabits high mountains in the Mediterranean and sub-Mediterranean regions. Nineteen populations of P. heldreichii from the Western Balkans encompassing 187 individual trees were examined to evaluate morphological variation, a rarely studied aspect of the species. Univariate and multivariate statistics were applied in order to assess the variation of morphological traits of cones and seeds, evaluate the relationships among the sampled populations and verify geographic differentiation in the Dinaric Alps versus Scardo-Pindic mountains. The observations of P. heldreichii covering the populations from the western margins and the centre of the species distribution range indicated a morphological variation among populations and their geographic structure. In general, the southern populations (Scardo-Pindic group) had lower values for the most of morphological traits than the northern ones (Dinaric group). The observed geographic differences between these populations exhibit a north-western to south-eastern gradient, with a few inconsistencies. The southernmost sampled population, Tomorr in Albania, showed remarkable morphological divergence from the other studied populations and appeared to be a distinct morphological group. The pattern of morphological variation in Bosnian pine most likely resulted from multiple effects of long-term isolation and fragmentation in high mountain systems, adaptation to extreme environments and human disturbances.

    The paper presents the results of the study on seed morphology of eight following Allium species: A. pyrenaicum Costa & Vayr., A. rotundum L., A. sphaerocephalon L., A. vineale L., A. moly L., A. karataviense Regel, A. fistulosum L. and A. nutans L. The study confirmed the substantial diversity in testa characters, especially curvature and relief of anticlinal walls as well as microsculpture of outer periclinal walls. The occurrence of raised anticlinal walls – an unusually rare feature in Allium seeds, previously observed only in a few species, was found in A. karataviense. It was also found that the testa type in A. pyrenaicum did not match the typical character combination, described before for subg. Allium sect. Allium.
    W pracy przedstawiono wyniki badań nad morfologią nasion ośmiu następujących gatunków rodzaju Allium: A. pyrenaicum Costa & Vayr., A. rotundum L., A. sphaerocephalon L., A. vineale L., A. moly L., A. karataviense Regel, A. fistulosum L. i A. nutans L. Obserwacje wykonano z zastosowaniem elektronowego mikroskopu skaningowego (SEM) oraz mikroskopu stereoskopowego. Przeprowadzone badania potwierdziły znaczne zróżnicowanie cech powierzchni nasion czosnków, a w szczególności przebiegu i reliefu ścian antyklinalnych oraz mikro-urzeźbienia zewnętrznych ścian peryklinalnych komórek testy. U A. karataviense stwierdzono występowanie wypukłych ścian antyklinalnych komórek testy – cechy niezwykle rzadko spotykanej u czosnków, wcześniej zaobserwowanej zaledwie u kilku gatunków. Stwierdzono również, że typ skulptury nasion A. pyrenaicum nie odpowiada typowej kombinacji cech komórek testy, opisanej wcześniej u innych gatunków podrodzaju Allium sekcji Allium.

    Erysimum pieninicum (Zapał.) Pawł. (Brassicaceae) is an endemic species, growing only in Pieniny Mts. The aim of the presented work was to investigate its pollen morphology as well as its ultrastructural traits of pericarp and seed-coat. Pollen grains of this species were of small size, 3-zonocolpate with reticulate ornamentation. The external siliqua surface was of rugose sculpture, covered by numerous, stellate hairs. The internal surface of the fruit was naked and characterized by striate sculpture. The seed-coat ornamentation of E. pieninicum was of blister type.

    Opis:
    The genus Taraxacum is taxonomically complicated due to apomixis. Therefore, there are significant differences in knowledge of regional Taraxacum-Floras among European countries. Similarly, some taxa are well characterised with well-known distribution, whereas some ones are known e.g. from a single locality. Taraxacum scanicum of section Erythrosperma is one of the most common microspecies of this section in Europe. Recently, this taxon was split into three microspecies. In this study we map the distribution of three described taxa of this group in Poland, i.e. T. scanicum s.s., T. prunicolor and T. cristatum. The survey showed that T. scanicum has a similar distribution as T. prunicolor in Poland. This is in contrast with the hitherto known distribution of both taxa. T. cristatum was found at a single locality that is quite distant from the distribution in southern central Europe. We also provide with new morphological characteristics of achenes and pollen for T. scanicum s.s. and T. prunicolor.

    Opis:
    Polar vascular plants native to the Arctic and the Antarctic geobotanical zone have been growing and reproducing effectively under difficult environmental conditions, colonizing frozen ground areas formerly covered by ice. Our macroscopic observations and microscopic studies conducted by means of a light microscope (LM) and transmission electron microscope (TEM) concerning the anatomical and ultrastructural observations of vegetative and generative tissue in Cerastium arcticum, Colobanthus quitensis, Silene involucrata, plants from Caryophyllaceae and Deschampsia antarctica, Poa annua and Poa arctica, from Poaceae family. In the studies, special attention was paid to plants coming from diversity habitats where stress factors operated with clearly different intensity. In all examinations plants, differences in anatomy were considerable. In Deschampsia antarctica the adaxial epidermis of hairgrass leaves from a humid microhabitat, bulliform cells differentiated. Mesophyll was composed of cells of irregular shapes and resembled aerenchyma. The ultrastructural observations of mesophyll in all plants showed tight adherence of chloroplasts, mitochondria and peroxisomes, surface deformations of these organelles and formation of characteristic outgrowths and pocket concavities filled with cytoplasm with vesicles and organelles by chloroplasts. In reproduction biology of examined Caryophyllaceae and Poaceae plants growing in natural conditions, in the Arctic and in the Antarctic, and in a greenhouse in Olsztyn showed that this plant develops two types of bisexual flowers. Almost all ovules developed and formed seeds with a completely differentiated embryo both under natural conditions in the Arctic and the Antarctic and in a greenhouse in Olsztyn.

    Opis:
    Pinus densiflora f. multicaulis is a rare and unusual form of genus Pinus. It has excellent ornamen- tal values due to many trunks from its root collar, and produces female, male, and bisexual strobili on the same tree. However, there is limited study whether the bisexual strobili are functional, mature lateral cones produce filled seeds, and the seeds from the mature lateral cones germinate and grow as well as those from mature apical cones. The structure of apical female, and lateral male and bisexual strobili were analyzed in an open-pollination-progeny population. The strobili were photographed to obtain external, cross-section, and radial-section images using a 45× stereoscopic microscope. Radial sections of strobili were imaged using scanning electron microscopy. Characteristics of apical and lateral cones and seeds were surveyed by cone analysis and germination test. P. densiflora f. multicaulis developed typical female strobili apically, and ordinary male and bisexual strobili laterally. Additionally, female strobili developed laterally whereas the male strobili were normally located. The mature lateral female strobili had the same structure as the apical female. In the mature bisexual strobili, the proportion of male and female tissue was unequal. The cones developed from lateral female strobili showed highly significant differences in the length, width, and weight, being shorter (32.7%), narrower (26.9%), and lighter (59.8%) than those from apical female strobili. Both types produced filled seeds and seedlings, and well significant positive correlations were found among characteristics of seeds from apical and lateral female strobili. The initial seed germination rate of the seeds from apical female strobili was higher than that of seeds from lateral female strobili, but the difference decreased over time. The viability and spatial distribution of the female and male tissue of bisporangiate cones, and their frequent occurrence suggests a common mechanism for the production of bisporangiate structures in seed plants.

    Opis:
    Quercus alnifolia is an endemic species in Cyprus, and it is rated as Vulnerable (VU) in the Red List of Oaks. Although Q. alnifolia has a great ecological importance, there are only few studies about this species. In this work we have studied the natural variability of this species by analyzing acorn dimensions, acorn mass, length of embryo, moisture content of acorns and seed germinability among the seven acorn provenances, collected in Cyprus. We also determined the seeds responses to drying. Germination trials were also carried out, and differences in seed germination among populations were examined. Rate of water loss and its effect on seed germination was also estimated by application of specific desiccation treatments. The results showed that acorn characteristics significantly differed between the populations, following a general trend to reduce their dimensions and mass with the altitude increase. Seed germination was high for all studied populations, and germination behaviour was similar for all populations. Desiccation of acorns below 35% resulted in a great reduction of seed germination capacity.

    Opis:
    The morphology and anatomy of generative organs of Salsola kali ssp. ruthenica was examined in detail using the light (LM) and scanning electron microscopy (SEM). The whole flowers, fruits and their parts (pistil, stamens, sepals, embryo, seed) were observed in different developmental stages. In the first stage (June), flower buds were closed. In the second stage (August), flowers were ready for pollination/fertilization. In the third stage (September), fruits were mature. Additionally, the anatomical and morphological structure of sepals was observed by means of LM and SEM. Thanks to the transverse and longitudinal semi-sections through sepals, the first phase of wing formation was recorded by SEM. The appearance of stomata in the epidermal cells of sepals above the forming wings was very interesting, too. The stomata were observed also in mature fruits.
