Abstract: Carex pallens (Fristedt) Harmaja, a new species for the flora of Poland, was found in four localities in the calcareous area of the Cracow-Częstochowa Upland and Góry Świętokrzyskie Mts. in central Poland. The most important differences between C. pallens and the morphologically similar C. digitata L. are given. The habitat and geographical distribution of C. pallens in Poland are provided. The chromosome number 2n = ca 51 is reported.

Abstract: Dendrothele Höhn. & Litsch. em. Lemke is a little-known genus represented by fungi growing on the bark of living trunks. In Europe 12 species of the genus are known, four of which have been known from Poland. Dendrothele griseocana (Bres.) Bourd. & Galz. is now reported as new to the country. The morphology of Polish specimens of D. griseocana, its ecology and general distribution are discussed. A key for determination all European species is provided.

Abstract: Ditiola peziziformis (Lév.) Reid is reported for the first time from the Polish Carpathians. In other parts of Poland it has been recorded from five localities. The morphology of basidiocarps and the ecology of this species from the new site are given. Fagus sylvatica L. is a new Polish host for Ditiola peziziformis, reported here. Previously it has been found in Poland on Abies alba Mill., Betula L. and Quercus L. Evidently the fungus survives in natural forests only and seems to be seriously threatened.

Abstract: A phytosociological study of a community dominated by Talinum paniculatum in Kampala, Uganda, was carried out in 1998. This plant community grows in cultivated and ruderal areas, especially under shade, during the rainy season. A total of 78 species was recorded, most of them annual, anemochorous and widespread. This community is characterized by two different strata: the upper one, about 10-30 cm high, composed mainly of Talinum paniculatum; and the lower one, about 0-10 cm high, comprised of many different plant species. The Talinum paniculatum community has been described as a new association, Talinetum paniculati ass. nov., belonging to the Bidention pilosae Lebrun alliance in Mullenders 1949 which comprises plant communities occurring in cultivation, postcultivation and ruderal habitats.
