The two pondweed taxa, new for the Polish flora, were found in the Drawa River in the Drawieński National Park (north-western Poland). Patches of P. x sparganiifolius started about 400 m below the mouth of the left-bank tributary, the Korytnica River, and ended about 5.5 km further downstream. The population colonized mainly a sandy substrate with varied particle size, moderately deep water, and moderate...
The study object consisted of 28 microhabitats of five Utricularia species localized in the Province of Lower Silesia, Poland. The aim of the study was to analyse the chemical properties of water and to present the differentiation of microhabitats in respect of their chemism, i.e., whether there are differences between the microhabitats, and which of the Utricularia species show the highest tolerance...
The research was carried out in north-eastern Poland in the vicinity of the village of Haćki (52°50’00’’N; 23°11’20’’E). This area is distinguished by an exceptionally numerous agglomeration of kames (10). Previous archaeological and soil research showed that kames have been inhabited by man from the iron age, and that the following stages of colonization are reflected in three levels of fossil soils...
The paper deals with the richness and diversity of endemic and subendemic taxa in the Polish Carpathians. Based on critical studies in the literature and the authors' unpublished materials collected in the field, the distribution patterns of endemic species are analysed and discussed. The participation of endemics in the flora of single Carpathian ranges is assessed and analysed. The importance of...
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...
Two new localities of Orobanche mayeri (Suess. & Ronniger) Bertsch & F. Bertsch, one of the rarest representatives of the family Orobanchaceae in Europe, are reported from southern Poland. The species was recorded in the Pieniny Mts (Central Western Carpathians) in July 2009. The hosts, abundance and habitat preferences at the new localities are described and a supplemented map of the distribution...
Lathyrus aphaca, which is in Poland considered to be an ephemerophyte recorded mainly in the north-west and the south-west, has lately been observed in arable fields in the south of the country. Recent and historical data on the distribution of the taxon in Poland are presented. Original relevés conducted in arable fields in Poland are analysed and compared to those from the Czech Republic, Germany...
Two localities for Huperzia selago subsp. arctica are recorded from Lithuania, to the south of its known distribution area. The habitats of this subspecies are cutover peatlands whose natural vegetation was disturbed 6-8 years ago during peat exploitation. One of the dominant species of latest vegetation cover is the invasive bryophyte Campylopus introflexus. Characteristics of the habitats of H....
The morphology and anatomy of the monotypic genus Trizeuxis make this taxon almost impossible to recognize in fossil material and hereby difficult object of historical geographic studies. To estimate the distribution of potential refugia during the last glacial maximum and migration routes for Trizeuxis the ecological niche modeling was performed. The potential niche modeling was done using maximum...
Montia linearis is a vascular plant originating from western North America. The expansion of this species has been observed for several decades. For the first time M. linearis was found in Europe in 1989. Further six populations were documented by 2004 within the continent: three in Poland, two in Denmark and one in Hungary. Apart from discovering a new population of M. linearis, we confirmed two...
