The distribution of Montia fontana L. in Poland is described, based on accessible data. Maps showing the distribution of M. fontana agg., subsp. amporitana, subsp. chondrosperma are presented, as well as lists of localities with brief descriptions of taxonomic characteristics of the subspecies and their habitats.
The Giant Horsetail (Equisetum telmateia) is the only representative of Equisetum genus included in the list of strictly protected species. In Central and Western Europe the species is found in communities belonging to alliances: Alno-Padion and Calthion. With progressing destruction of these biotopes, one can observe the phenomenon of this species moving to the habitats extremely anthropogenic in...
Activity of soil dehydrogenase (DHA) was measured in the mineral soil in a forest stand of 15 to 16-year-old Scots pine (Pinus sylvestris L.) from geographically diverse populations, as an indicator of biological activity of soil microorganisms, in a provenance experiment in Poland. The pine populations originated from six European countries (Sweden, Russia, Latvia, Poland, Germany, France) and differed...
Two closely related species of the genus Barbilophozia: B. lycopodioides and B. hatcheri were studied in populations from the Tatra Range (S Poland), where they are frequent and widely distributed. Both species play an important role in plant communities and grow here very often side by side. Typically developed plants are quite easy to distinguish (even in the field), however morphologically intermediate...
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...
The authors describe the locality of a so far in Poland unknown species Coleanthus subtilis. It was discovered on the Oleśnica Plateau near Wroclaw. This grass occurs on a surface of ca. 15 ha, round muddy shores of fishponds. The large stand makes the impression to be at least 50-year old. Together with the grass of our interest there grow also other, not frequent to day, species like Veronica peregrina,...
This paper presents the results of a floristic study focusing on taxa representing the genus Gomphonema in Kobylanka stream, situated ca 30 km NW of Kraków. Species belonging to the genus Gomphonema Ehr. were very frequently observed diatom taxa in the material studied. Amongst 272 diatom taxa recorded in the studied material, 13 belong to this genus. Some of them are widespread and often found in...
This study present 9 species of colourless euglenoid flagellates found in a small peat bog in Budzyń, a village north-west of Cracow, which belongs to the Małopolska Upland (Southern Poland). This threatened peat bog is covered with rubble brought from neighbouring Cracow. Only ca 30% of its area is relatively little influenced by human activity. Many of the present species are rarely and infrequently...
The Carpathians, particularly their highest massif, the Tatra Mountains, exhibit the greatest richness of endemics in Poland. The present paper is a critical recapitulation of existing knowledge of endemism among the vascular plants of the Polish part of the Carpathians. It comprises a list of all 110 taxa (49 species, 26 microspecies of the genus Alchemilla and 35 conspicuous subspecies) that can...
Information on Potamogeton hybrids, their identification, taxonomy, ecology and distribution has not been sufficiently recognised yet. Based on characters of P. x salicifolius (= P. perfoliatus x P. lucens) from a new locality in Poland - the Gatno lake (the Kaszuby Lakeland in NW Poland) - general comments on Potamogeton hybrids identification are introduced. The description of P. x salicifolius...
Data concerning morphology, ecology and distribution of Polish representatives of the genus Xerula Maire are discussed in the paper. All available specimens of X. pudens and X. melanotricha from Polish herbaria were reexamined to verify their identity and geographical distribution. Several new localities of X. melanotricha in the country are provided. A key to European taxa of the genus is proposed.
The paper presents a rush community new to Poland - Scirpetum radicantis Hejny in Hejny et Husak 1978 em. Zahlh. 1979, belonging to the Phragmition alliance. It was discovered in fishponds near Olesno in Silesia (SW Poland). The floristic composition and the ecological requirements of this association are presented in the paper. Scirpetum radicantis is considered to be a very rare and endangered plant...
Ascocoryne turficola, one of the rarest fungi in Europe, has been recorded for the first time in Poland. Its distribution presented on the map, ecological notes and morphology of ascocarps are based on the authors' own material.
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 morphological properties of Schizothyrioma ptarmicae (Helotiales, Ascomycota), a fungus known from a single locality in Poland and infrequently reported from Europe, are described and illustrated. Schizothyrioma ptarmicae is a parasite of leaves of Achillea ptarmica. It has been found in the Myrico-Saliceto auritae and Cirsio-Polygonetum plant associations of the Słowiński National Park. Additionally,...
Morphological properties of sporocarps and spores of Endogone lactiflua (Zygomycota, Endogonales), a fungus for the first time found in Poland, are described and illustrated. Endogone lactiflua was wet sieved and decanted from a sample taken from the zone extending from the upper soil layer to rhizosphere of Pinus sylvestris growing in a forest dune in northern Poland. The recovered spores mainly...
The present study showed the ecological differentiation of phytocoenoses dominated either by Myriophyllum alterniflorum or by Littorella uniflora, which in Poland are classified within the Myriophylletum alterniflori or Myriophyllo-Littorelletum association. The properties which best differentiated the waters of the above types of phytocoenoses were calcium and factors associated with the carbonate...
The distribution of four species of the genus Vulpia [V. myuros (L.) C.C. Gmel., V. bromoides (L.) S.F. Gray, V. ciliata Dumort. and V. geniculata (L.) Link] reported in Poland has been studied. Currently, V. myuros and especially V. bromoides are very rare species, and their greatest concentration can be found only in the Lower Silesia region. The number of their localities decreased after 1950 and...
A preliminary red list of threatened lichens of Lower Silesia (SW Poland) is presented. Species have been valuated according to the Red Data Book Categories (IUCN). The list comprises 602 taxa (ca. 60% of the whole lichen flora of Lower Silesia). 52 species are considered as rare (category R), 84 - as vulnerable (V), and 63 species - as endangered (E). The Silesian lichen flora is characterized by...
