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 Nanocyperion flavescentis, were specified. They were the following: I. Hyperico-Spergularietum rubrae and II. Centunculo-Anthocerotetum. I. The Hyperico-Spergularietum community occurred only on lowlands, on the sand and silt soils belonging to rye complexes. It was divided into two variants: with Illecebrum verticillatum and the typical one. II. The Centunculo-Anthocerotettum was met as well on lowlands, as on highland agricultural utility compelxes. The highland form of the community, differentiated into two variants: with Hypericum humifusum 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)
