The characteristics of communities found in unploughed stubble fields of the Mazowiecki Landscape Park and its agricultural buffer zone are presented in the paper. The association <i>Echinochloo-Setarietum</i> divided into a typical variant, the variant with <i>Galinsoga parviflora</i>, and the variant with <i>Bidens tripartite</i>, was the most frequently noted and floristically differentiated association. Patches of <i>Digitarietum ischaemi</i> were also frequently observed in stubble fields on the poorest habitats. Rarely, on fertile soils, small patches of floristically rich communities with <i>Veronica agrestis</i> were recorded. Periodically, excessively wet habitats were seldom occupied by the speciesrichest phytocoenoses of <i>Centunculo-Anthoceretum punctati</i>. Single patches of the community with <i>Setaria pumila</i>, the form with <i>Aphanes arvensis</i>, were observed only in the south-eastern part of the Park.

Dam Building

Labudovo okno locality (50 m-84 m elevation) is situated in the south-eastern part of the edge of the Pannonian Plains, resting along the left bank of the Danube between 1982 km and 1078 km. The investigated locality is the result of rise of the Danube level after dam building of the hydroelectric power station Djerdap I. The vegetation comprises aquatic associations of the classes Hydrochari-Lemnetea Oberd. 1967 and Potametea Tx. et Prsg. 1942. The class Hydrochari-Lemnetea Oberd. 1967 includes the following phytocoenoses: Lemno-Spirodeletum W. Koch 1954, Salvinio-Spirodeletum polyrrhizae Slavnic 1956, Lemno minoris-Azolletum filiculoides Br.-Bl. 1952, Ceratophylletum demersi (So? 27) Hild 1956. The class Potametea Tx. et Prsg. 1942 includes the associations Myriophyllo-Potametum So? 1934, Nympaeetum albo-luteae Nowinski 1928, Trapetum natantis M?lleret G?rs 1960.

Marine Terraces

The plant communities with Arenaria pseudofrigida are common on the cobble-loam grounds on the edges of marine terraces on the Vaigach, Dolgiy and few smaller islands in the south-eastern part of the Barents Sea. These communities influenced by sea salty spray are described within 4 new synataxa (2 associations and 2 subassociations). They are provisionally placed within the alliance Arenarion norvegicae Nordh. 1935. order Thlaspietalia rotundifolii Br.-Bl. in Br.-Bl. et Jenny 1926, class Thlaspietea rotundifolii Br.-Bl. 1948.

The Eu

Part I deals with the <i>Panico-Setarion</i> stubble plant communities. Part II describes the <i>Eu-Polygono-Chenopodion</i> plant communities. Part II is based on 89 photosociological records. The <i>Eu-Polygono-Chenopodion</i> plant communities develope on soil rich in nutrients (brown soil developed from silts loess and clay; alluvial soils developed from silts and loams; chernozem and black soils), belongs to wheat complexes. Two plant communities are distinguished: 1) <i>Oxalis stricta-Euphorbia esula</i> community; 2) <i>Veronica persica</i> community divided into four variants. The floristic diversity of these plant communities reflects the ecological conditions of the examined region.

Setaria Glauca

Floristic diversity is characteristic for stubble-field plant communities. Those communities consist of both the species remaining after harvesting of grain and of the species developing in rootplant communities. The first part of this paper describes the plant communities of poor sites in the investigated region. It is based on 90 phytosociological records taken in August and September of 1972-1975 and on soil investigations. The <i>Panico-Setarion</i> alliance was made up of: 1) the <i>Digitarietum ischaemi</i> association, 2) the <i>Setaria glauca</i> community and 3) the <i>Ecbinochloo-Setarietum</i> association, the <i>Setaria glauca</i> community was divided into smaller phytosociological units.

Different Soils

In the years 1972-1975, between August and September, on lowlands and on the area elevated to 500 m over the sea level, 85 phytosociological records were taken. On the wet stubble-field of the tested area two associations of tiny plants, belonging to the alliance <i>Nanocyperion flavescentis</i>, were specified. They were the following: I. <i>Hyperico-Spergularietum rubrae</i> and II. <i>Centunculo-Anthocerotetum</i>. I. The <i>Hyperico-Spergularietum</i> community occurred only on lowlands, on the sand and silt soils belonging to rye complexes. It was divided into two variants: with <i>Illecebrum verticillatum</i> and the typical one. II. The <i>Centunculo-Anthocerotettum</i> was met as well on lowlands, as on highland agricultural utility compelxes. The highland form of the community, differentiated into two variants: with <i>Hypericum humifusum</i> and the typical one, occurred in the mountain wheatland complex, on brown silt soils. The lowland form of the community in a typical variant was found on different soils and complexes (1, 2, 4, 5, 8).

Setaria Glauca

In the Part I and II the stubble-field plant communities of lowlands agricultural utility complexes in South-Eastern Poland were introduced. The Part III contains a description of such communities occurring in mountain complexes. In the years 1972-1975, since August till September, 95 phytosociological records were taken on the area elevated from 300 to 650 m over the sea level, embracing the Carpathian Foreland and the Low Carpathian region. The research was conducted upon the typical, acid and leached brown soils, as well as on clay, dusty clay and silt alluvial soils belonging to three mountain complexes: wheat, cereal and oat-potatoes. The following communities were specified: I. <i>Setaria glauca</i> community, divided into two variants: 1) typical; 2) with <i>Aphanes arvensis</i>; II. <i>Veronica persica</i> community, divided into four variants: 1) with <i>Aphanes arvensis</i>, 2) typical, 3) with <i>Geranium dissectum</i>, 4) with <i>Aethusa cynapium</i>. The variant with <i>Geranium dissectum</i>, belonging to the community with <i>Veronica persica</i>, was considered as having the most mountain character.
