Les Scrophulariaceae dans la flore d'Afrique centrale (excl. Lindernieae).

Abstract: The family Scrophulariaceae in Central Africa, an area defined here as including Zaire, Rwanda and Burundi and covering an area of 2 399 697 km², consists of 42 genera and 186 species, divided into three subfamilies, the Scrophularioideae, the Rhinanthoideae and the Orobanchoideae. The type subfamily comprises eight tribes, Verbasceae, Aptosimeae, Cheloneae, Gratioleae, Lindernieae, Hemimerideae, Selagineae and Antirrhineae with 24 genera and 84 species. Of these, only the Lindernieae had been already fully revised for the whole tropical Africa. The subfamily Rhinanthoideae comprises three tribes with 17 genera and 100 species. Finally the remaining subfamily of the Orobanchoideae comprises a single tribe with a single genus and a single species, only. The present paper is a taxonomic revision of all the tribes excluding the Lindernieae. A total of 37 genera and 139 species, some of them with infraspecific taxa including subspecies and varieties are recognized. All taxa are fully described and drawings for 74 species are given. In addition, keys to subfamilies, tribes, genera, species, subspecies and varieties, as well as ecological and phytogeographic data are provided to assist in the correct identification of the taxa. Buchnera bampsiana Mielcarek, B. dilungensis Mielcarek, B. libenii Mielcarek, B. philco­xii Mielcarek, B. robynsii Mielcarek, B. symoensiana Mielcarek, B. vandenberghenii Mielcarek and Harveya wysockiana Mielcarek are described as new species. Furthermore three new combinations, Sopubia conferta S. Moore var. congensis (S. Moore) Mielcarek, S. mannii Hemsl. & Skan var. metallorum (Duvign.) Mielcarek and S. parviflora subsp. eminii (Engl.) Mielcarek, are made. In addition, nine new sections and four subsections are described. The maximum of the occurence of the Central African Scrophulariaceae is in the submontane and lower montane zone, generally between 600 and 2200 m. They are mostly associated with open formations of savannas, especially steppe savannas in the high plateaux, as well as woodlands. From the equatorial forest only two species are reported, Harveya thonneri De Wild. & Dur. and Striga hallaei Raynal. The overwhelming majority of the Central African Scrophulariaceae is concentrated in Haut-Katanga (98 species, including 25 probably endemic) and Burundi (51 species).

Rubus kuleszae (Rosaceae) - a new bramble species of section Corylifolii from Poland.

Abstract: Rubus kuleszae Zieliński, a species new to science is described from Poland and the Czech Republic. The new bramble species is similar to R. grossus H. E. Weber in its robust habit and large leaves, but differs in the undulate margin of the leaflets, the inflorescences leafy to the apex, the pilose ovaries and the deflexed sepals. R. kuleszae is widespread in southern Poland and scattered in the Czech Republic.

Habitat variability of the phytocoenoses of Isoëto-Lobelietum in Poland.

Abstract: A comparative analysis of the habitats of the two main subassociations of Isoëto-Lobelietum, i.e. Isoëto-Lobelietum lobelietosum and Isoëto-Lobelietum isoëtetosum, was conducted. It is demonstrated that the phytocoenoses of Isoëto-Lobelietum isoëtetosum occupy not only deeper sites of the lake littoral but they are also restricted to more acidic soft waters richer in Cl, NH₄-N, SO₄ and Na but poorer in total Fe and Ca than those of Isoëto-Lobelietum lobelietosum. The substrates of Isoëto-Lobelietum isoëtetosum are more acidic and richer in organic matter, various forms of N, PO₄-P, K, total Fe, Na, Cl, and Mg, but generally poorer in SO₄. The results obtained in Poland indicate that the present syntaxonomic status of Isoëto-Lobelietum evidently needs further clarification. The phytocoenoses of Lobelia dortmanna L. and those of Isoëtes lacustris L. can be classified as distinct associations i.e. Lobelietum dormannae and Isoëtetum lacustris.

Dispersion des pollens en milieu urbain (banlieue sud de Paris - 1993).

Abstract: Comparison is made between a list A of species growing in a southern Paris suburb and two lists of species, B and C, from the same locality and compiled at the same time, based on methods of pollen dispersal. Wind pollination (B) was investigated by examining the pollen content of raindrops, and insect pollination (C) assessed using 20 Hymenoptera. List A consisted of 49 nature and 77 introduced species, representing 52 families. 59 taxa (55 families) were found in list B and 46 taxa (44 families) in C. 38 taxa were common to B and C. Pollination by wind involved 42% of the plant families. Insect pollination was found in 77% and occurred in 31 families (60%) of the introduced taxa. Hymenoptera are important pollinators of introduced species which provide them with an abundance of varied nutrients. The small number of Hymenoptera present was probably a result of mechanical disturbance and chemical pollution of the urban environment.

The bryoflora of urban areas - a floristic-ecological case study of Oświęcim town (S Poland).

Abstract: In spite of strong human pressure on habitats, Oświęcim and its surrounding area have a relatively rich bryoflora - 129 species, including 15 liverworts and 114 mosses. 34 species should be regarded as locally threatened. The occurrence of particular taxa in relation to habitats and substrata is analysed. Furthermore the occurrence of the bryophytes life and morphological forms in the main types of microhabitat and observations relevant to their reproduction under the influence of strong human pressure are presented here.
