    Opis:
    The paper presents the taxonomical position and the description of the characteristic features of Macrosciadium alatum (=Ligusticum alatum). The species was recorded in the Western Bieszczady Mts (the northern part of the Carpathians) in July 2007 and is new to the flora of Europe. Its natural range comprises mainly the Caucasus region and the origin of M. alatum in south-east Poland is quite puzzling. The species has most likely been deliberatelly brought into the area. M. alatum spreads quite intensively. It penetrates semi-natural vegetation systems and seems to be expansive.

    Opis:
    The aim of the work was to estimate the specific role that Central European botanic gardens play in the dispersal of alien plants, which results from the wide variety of plants cultivated in the gardens and regular international exchange of plant material between these institutions. We compared the results of recent field studies (in eight Polish botanic gardens) and a review of older literature data and herbarium collections (from Central European botanic gardens). We found that in Poland the proportion of botanic garden escapes was lower (3%) than would be expected from the "tens rule". Botanic gardens have played a considerable role in the development of the synanthropic flora of Central Europe in the last 200 years. We determined a group of species introduced through a network of botanic gardens and propose 5 theoretical patterns to describe the mode and pathways of the early stages of introduction of these species.

    Opis:
    Glyceria striata (Lam.) Hitchc. is a North American species that has been recorded in most, semi-natural habitats in Europe, e.g. in meadows, bog springs, margins of water bodies. It is circumscribed within two taxa of lower rank: G. striata subsp. striata and G. striata subsp. stricta. Only G. striata subsp. stricta has been reported from Europe. This paper gives a list of the European localities of the species (48) and describes two newly discovered localities in Poland (the Wyżyna Małopolska upland and the Western Carpathian Mts.). The distribution of G. striata in Europe is mapped and potential migration routes of the species are discussed.

    Opis:
    In this paper we have analysed invasive flora of Medvednica Nature Park, Croatia with respect to their origins, life forms, systematic positions, types of seed dispersal, Ellenberg indicator values and spatial distributions using MTB 1/64 grid units for analyses. A total of 27 invasive plant species, belonging to 14 families, were recorded with Asteraceae being the most frequently occurring family. Therophytes were the most common life form, as is generally true of Croatian invasive plants; however, hemicryptophytes and geophytes were more frequent in Medvednica. Here, invasive plants originated mainly from both Americas with slightly lower portion in comparison to all Croatian invasive plants, while contrary was the case when comparing those originated from Asia. The most widespread species was Erigeron annuus (L.) Pers., and the species with the lowest occurrence were Chamomilla suaveolens (Pursh.) Rydb and Datura innoxia Mill. A multiple regression model explains 44% of the spatial variability in the invasive plants data per MTB 1/64 unit, using the number of all recorded plant species, the average elevation and the lengths of paths and roads as estimators. The latter two variables also had the most influence on the ordination axes in analyses of the spatial distribution of seed dispersal types present in each MTB 1/64 unit. Anemochory was the most frequent type of seed dispersal.
