Contribution to the flora of Asian and European countries: new national and regional vascular plant records, 8
The paper presents new records of 24 vascular plant species from 11 Eurasian countries. One taxon (Orobanche laxissima) is reported from Armenia ; one (Epipactis condensata) from Azerbaijan ; two (Phragmites americanus, Polygala multicaulis) from Belarus ; one (Stipa caucasica) from Egypt ; one (Puccinellia hauptiana) from Kyrgyzstan ; three (Aquilegia xinjiangensis, Geranium saxatile, Ranunculus songaricus) from Mongolia ; one (Stipa roborowskyi) from Pakistan ; three (Echinochloa muricata, Erigeron acris subsp. podolicus, Hypericum majus) from Poland ; six from Russia, whereof one (Zanthoxylum armatum) from the European part of Russia and five (Chaerophyllum aureum, Elsholtzia densa, Poa …
Formalized classification of ephemeral wetland vegetation (Isoëto-Nanojuncetea class) in Poland (Central Europe)
Formalized classification of the class Isoëto-Nanojuncetea has not been performed in Poland. We used 69,562 relevés stored in Polish Vegetation Database. Based on the literature and expert knowledge we selected 63 diagnostic species for the Isoëto-Nanojuncetea class. Unequivocal classification was applied in this work according to Cocktail method. A set of formal definitions was established using a combination of logical operators of total cover of species in case of high-rank syntaxa while sociological species groups and cover of particular species were used for logical formulas describing class, alliances and associations. An Expert System was prepared and applied to classify the whole da…
Current distribution of Pilularia globulifera L. in Poland – changes of geographical range and habitat preferences
<em>Pilularia globulifera </em>is a subatlantic European fern threatened with extinction. In Poland, it reaches the eastern border of its continuous range. Up to the end of the 20th century, it was observed here in 21 stands; only 2 of them existed by the second half of the century, so the species was categorized as critically endangered. Five new locations have been found in western and northwestern Poland during the last 10 years. Abundant and permanent populations grow in 3 locations, while 2 stands were ephemeral. All the current stands are situated in anthropogenic habitats with spontaneous vegetation, in oligotrophic to eutrophic waters. One of the new localities is about …
