    Opis:
    A good knowledge of species delimitation is crucial for the biodiversity protection and the conservation of wild species. We studied the efficiency of AFLP markers and morphological characters to assist species determination for Melica ciliata L. and M. transsilvanica Schur within European range of distribution, including isolated and range-limit populations of "M. ciliata" (i.e. M. cf. ciliata) from the Polish Sudetes, where it is regarded as critically endangered. AFLP markers were found to be more effective then morphological characters (more or less continuous) in distinguishing the both studied species. AMOVA revealed very low genetic diversity within populations and high differentiation among populations of M. ciliata and M. transsilvanica (FST = 0.89 and 0.95, respectively). The species-diagnostic AFLP markers of M. transsilvanica shared with "M. ciliata" from the Sudetes were detected. On the other hand, no species-diagnostic genetic markers of M. ciliata or hybrid-diagnostic markers of M. × thuringiaca were found within "M. ciliata". PCoA and NJ showed an overlapping genetic diversity of "M. ciliata" and M. transsilvanica. Hierarchical AMOVA supported the absence of a significant genotypic distinction between "M. ciliata" and M. transsilvanica. ANOVA showed that the length ratio of lower to upper glumes was the best morphological character to discriminate between M. ciliata and M. transsilvanica. Combined morphological and genetic data show that M. ciliata is not currently present in Poland as its putative Polish populations represent M. transsilvanica. A significant decrease in genetic variability that could influence viability was not observed the in Sudetian populations of M. transsilvanica. However, the population size changes significantly as a result of plant succession. Correction of the northern limit of the continuous distribution of M. ciliata L. in Central Europe is presented.

    Opis:
    This paper presents the results of the study on morphological variability of leaves of a scattered tree species Sorbus torminalis (L.) Crantz) in Poland. The leaves from short- and long shoots were collected from 17 localities widespread within the range of the species in Poland. Leaves were measured according to 15 morphological traits. The biometric data were subjected to multivariate statistical analysis in attempt to define variability between local populations. Most of the leaf traits are significantly correlated and are characterised by moderate level of variation. The average among population component of variation was 32.82% and 27.46% for leaves on short- and long shoots, respectively. The differences between sampled populations are significant, but only a weak geographical pattern of this differentiation was detected. Clinal type of variation was ascertained in two traits. Leaf traits which discriminate best the studied populations are also indicated. It was proved that leaves on short shoots differ markedly in shape and size from those of long shoots. Leaves on long shoots are steadier, but morphological trait values are less correlated. The study also confirmed the occurrence of individuals with leaves characteristic for S. torminalis var. perincisa Borbas et Feck and S. torminalis f. mollis Beck in a few Polish populations.

    Opis:
    The morphological diversity in 25 populations of two native species of Brachypodium occurring in Poland, was studied. Principal component analysis and cluster analysis of morphometric data segregate specimens or populations of Brachypodium into two groups, corresponding to the two species. In most of morphological characters, B. pinnatum and B. sylvaticum are similar to each other. However, in terms of characteristics, such as the hairiness of culms and leaf-sheaths both can also vary much within a single population. In comparison with B. pinnatum, B. sylvaticum always has pubescent abaxial palea surfaces. Apparent differences were not detected between the two ecotypes of B. pinnatum named "Grassland" and "Woodland".

    The ontogenetic development and morphological properties of spores of two species of arbuscular mycorrhizal fungi (Glomeromycota) of the genus Glomus, G. claroideum and G. spurcum, are described and illustrated. Spores of the two species were not earlier found in Poland, and this paper is the first report of the occurrence of G. spurcum in Europe. In one-species pot cultures with Plantago lanceolata as the host plant, the mycorrhizae of G. claroideum consist of arbuscules, vesicles, as well as intra- and extraradical hyphae staining intensively with trypan blue. Glomus spurcum mycorrhizae were not recognized, because many attempts to establish one-species cultures of this fungus failed. Additionally, the distribution of both the fungi in the world is presented.

    Opis:
    The results of the study on morphological variation of fruits and seeds of a rare forest tree species Sorbus torminalis (L.) Crantz in Poland are presented and discussed. The ripe fruits were collected from 13 localities widespread within the range of the species. Fruits and seeds were measured according to 13 morphological traits. The biometric data were subjected to multivariate statistical analysis in attempt to define intra and inter populational variation. Most of the fruit and seed traits are significantly correlated and are characterized by moderate level of variation. Traits describing size and shape are higher variable in seeds than in fruits. High level of variation within examined populations was ascertained. The average among population component of variation was only 23.99%. Though the differences between sampled populations are significant, almost no geographical pattern of this differentiation was detected. The biological significance of some of fruit and seed features is discussed in the paper. Examining the collected material a single fruits with 5–6 seeds were found what suggests the presence of three carpels in gynoeceum, a number not previously reported in the species.

    Opis:
    Common oregano is an important medicinal and aromatic plant, characterized by a high morphological and chemical variability. The aim of the work was to determine the diversity of 14 common oregano populations introduced into ex situ conditions, in respect of morphological and developmental traits as well as content and composition of essential oil in herb. Observations and harvest of raw material were performed in the second year of plant vegetation. Morphological and developmental characters were estimated. Total content of essential oil was determined according to European Pharmacopoeia 8th. The composition of essential oil was carried out by gas chromatography. Populations differed in respect of examined traits, i.a.: plant’s height from 52.13 to 88.66 cm, number of stems per plant from 45.6 to 123.3, number of internodes per stem from 4.6 to 9.2. Fresh mass of herb was at a level of 249.0–896.6 g per plant. Total content of essential oil ranged from 0.35 to 0.87%. Sabinene, 1,8-cineole, linalool, p-cymene, β-caryophyllene and caryophyllene oxide were the dominant compounds in essential oil. Number of stems and fresh mass of herb differentiated examined populations at the highest degree. Most of populations were classified as a sabinyl chemotype rich in sesquiterpenes.
    Lebiodka pospolita jest ważną rośliną leczniczą i aromatyczną, charakteryzującą się wysoką zmiennością morfologiczną oraz chemiczną.Celem pracy było określenie różnic pomiędzy 14 populacjami lebiodki pospolitej rosnącymi w warunkach ex situ, pod względem cech morfologiczno-rozwojowych, a także co do zawartości i składu chemicznego olejku eterycznego w zielu.Obserwacje przeprowadzono w drugim roku wegetacji roślin. Ocenione zostały cechy morfologiczno- rozwojowe, oznaczono zawartość olejku eterycznego (wg Farmakopei Europejskiej 8) oraz jego skład chemiczny (metodą chromatografii gazowej).Populacje różniły się pod względem analizowanych cech. Wysokość roślin wahała się od 52,13 do 88,66 cm, liczba pędów na roślinę od 45,6 do 123,3, liczba międzywęźli na pędzie od 4,6 do 9,2. Świeża masa ziela kształtowała się na poziomie 249,0–896,6 g na roślinę. Zawartość olejku wynosiła od 0,35 do 0,87%. Związkami dominującymi w olejku były: sabinen, 1,8-cineol, linalol, p-cymen, β-kariofilen i tlenek kariofilenu. Cechami, które najbardziej różnicowały badane populacje była liczba pędów oraz świeża masa ziela. Większość populacji zaklasyfikowano jako chemotyp sabinylowy, bogaty w seskwiterpeny.

    Opis:
    The paper presents results of geobotanical and taxonomic studies on the distribution and habitat requirements of Nymphaea candida in southern Poland. The researches were conducted in southern Poland in 2003-2009, in the provinces of Lower Silesia, Lublin, Małopolska, Opole, Silesian province as well as, in southern parts of Mazowieckie and Lubuskie. Flowers, leaves and fruits of Nymphaea species were collected from 27 locations. Altogether pollens from 73 populations of N. candida and 18 of N. alba from all the researched area were measured. The trophic level of an ecosystem was evaluated according to the results of the total nitrogen, total phosphorus, chlorophyll a, transparency and biological parameters. As the result of the studies of more than 200 water bodies, 57 localities of N. candida were documented within the investigation area. The populations of N. candida occupy mid-forest water bodies and river ox-bow lakes. A significant number of populations was also found in artificial reservoirs - fish ponds. The most suitable habitat conditions for N. candida occur in shallow waters in the shore zone with the amplitude of the water column vary from 0.5 to 2 m. Regarding the trophy level, N. candida occupies different habitats, mainly mesotrophic and also eutrophic with high content of organic matters. Considering the 15 checked morphological parameters, especially the stigma diameter, the number of carpellary teeth, flower and pollen diameters, the found and collected specimens of N. candida significantly differ from N. alba. The study confirms that N. candida ocurrs in whole lowland Poland without any regional distribution gaps. According to the IUCN guidelines to species assessment the data gathered during the presented study do not allow to classify N. candida as a vulnerable species in Poland. Still existing populations for more than 150 years, numerous stable locations, abundant populations, a habitat accessibility, a biotope extent, an ecological amplitude against the trophy level and direct human impacts suggest, that the species should be regarded as a least concern (LC) taxon.

    Opis:
    The basic aim of the work was to widen the knowledge about variation of Pinus mugo in the Karkonosze (Giant) Mountains and verification of provenance of several, probably planted populations on that basis. Seven populations were sampled, four on hardly accessible precipices of glacial cirques as natural, and three on the topical, mostly plane or only slightly in clined parts of the mountains as potentially alien ones. The variation of the needles was biometrically analyzed in respect of 23 morphological and anatomical characters. Measurement data were subject of multivariate statistical analyses. Results call attention on rather continuous variability of P. mugo in the Karkonosze Mts. The differences among samples were found as relatively low and no direct connections have been detected between variation and provenance from precipices versus plane sites.
