The paper presents a water plant community new to Poland - <em>Nymphaeetum albae</em> Vollmar 1947 em. Oberd. in Oberd. et al. 1967, belonging to the i class. It was discovered in fishponds in Pokój near Namysłów, Lasowice Małe near Kluczbork and small ponds in Staniszcze Małe near Opole in Silesia (SW Poland). Floristic composition and ecological requirements of this association are presented in the paper. <em>Nymphaeetum albae</em> is considered to be a rare and endangered plant community in Europe.

Natural water reservoirs are very valuable floristic sites, with springs particularly important for the preservation of floral biodiversity. This paper presents, as a case study, a community of water plants that is new to limnocrene karst springs in Europe: Potametum alpini (Potametea), found in Poland. The paper provides the floristic composition and ecological requirements of this plant association, which is rare and endangered in Europe. According to our knowledge, the habitat data presented here are unique as they are published for the first time for this plant community, and thus it is currently not possible to compare them with data from other authors. Our study confirms the importance of rare microhabitats for global biodiversity. Research on as yet unknown physical and chemical factors limiting the range and development of patches of different plant associations should be conducted intensively, because plant communities, including rare, endangered and protected examples, are an important element of biodiversity at both continental and local scales. All the issues discussed in the paper (rare microhabitats, endangered aquatic plant communities, global biodiversity) are important because they are related to the conservation and management of inland waters.

The five new steppe-meadow associations are des­cribed in the South Urals. They refer to the class Molinio-Arrhenatheretea R. Tx. 1937 em. R. Tx. 1970, ord. Galietalia veri Mirkin et Naumova 1986, all. Trifolion montani Naumova 1986, and the suball. Trifolienion montani Mirkin et Naumova 1986. The communities of these associations are typical of their richness in species, including such rare and endangered ones as Dianthus acicularis, Stipa korshinskyi, Stipa sareptana, Stipa zalesski, Stipa pennata, Stipa da­syphylla, Tulipa biebersteiniana etc., the fact which makes for their significant value for nature protection purposes.

A taxonomic revision of the Nystiellidae from Brazil, including samples from the Rio Grande Rise, South Atlantic, was performed based on shell morphology. Five genera and 17 species were recognized. For the richest genus,Eccliseogyra, the three species previously recorded from Brazil were revised:E. brasiliensisandE. maracatu, previously known only from their respective type series, were re-examined. Newly available material ofE. maracatuexpanded the known geographic range of this species to off south-east Brazil.Eccliseogyra nitidais now recorded from north-eastern to south-eastern Brazil, as well as from the Rio Grande Rise. Three species ofEccliseogyraare newly recorded from the South Atlantic:E. monnioti, previously known from the north-eastern Atlantic, occurs off eastern Brazil and on the Rio Grande Rise; its protoconch is described for the first time, confirming its family allocation.Eccliseogyra pyrrhiasoccurs off eastern Brazil and on the Rio Grande Rise, andE. folinioff eastern Brazil. The genusIphitusis newly recorded from the South Atlantic.Iphitus robertsiwas found off northern Brazil, although the shells show some differences from the type material, with less-pronounced spiral keels. Additional new finds showed thatIphitus cancellatusranges from eastern Brazil to the Rio Grande Rise, and Iphitusnotiossp. nov. is restricted to the Rio Grande Rise.Narrimania, previously recorded from Brazil based on dubious records, is confirmed, including the only two living species described for the genus:N. azelotes, previously only known from the type locality in Florida, andN. concinna, previously known from the Mediterranean. A third species,Narrimania raquelaesp. nov. is described from eastern Brazil, diagnosed by its numerous and thinner cancellate sculpture. To the three species ofOpaliopsispreviously known from Brazil, a fourth species,O. arnaldoisp. nov., is added from eastern Brazil, and diagnosed by its very thin spiral sculpture, absence of a varix, and thinner microscopic parallel axial striae.Papuliscala nordestina, originally described from north-east Brazil, is recorded off eastern Brazil and synonymized withP. elongata, a species previously known only from the North Atlantic.
