Abstract: Research on biodiversity of macrofungi of Danube islands Sihoť and Sedláčkov ostrov (city of Bratislava) resulted in 26 species of Ascomycetes. Ecology, chorology and taxonomy of selected taxa of Discomycetes and Pyrenomycetes was studied.
Šoltés R. & Novák A. (1999): Calliergon trifarium (Bryophyta) in the National Nature Reserve Belianske lúky (Poprad Basin, Slovakia) confirmed. – Thaiszia – J. Bot. 9: 11-14. – ISSN 1210-0420.
Abstract: During a bryological trip to the Belianské lúky National Nature Reserve, Poprad Basin on July 10, 1998 the authors refound a rare moss species belonging to the glacial relics – Calliergon trifarium. The species was refound in its original location after being reported by Šmarda in 1961. The species has not been reported over 37 years and its occurence was obscure. A relevé is included.
Kovanda M. (1999): Campanula ´ iserana (C. rhomboidalis L. ´ C. rotundifolia L.), a new hybrid in Campanula. – Thaiszia – J. Bot. 9: 15-18. – ISSN 1210-0420.
Abstract: The hybrid Campanula ´ iserana (C. rhomboidalis L. ´ C. rotundifolia L.) is described from near Jizerka, Jizerské hory Mts., Western Sudeten, Czech Republic. Here a small topodeme of the alien C. rhomboidalis L. is established, enclosed in an extensive C. rotundifolia L. population. The hybrid is rather variable, indicating that back-crossing with one or both parents takes place. C. rhomboidalis L., accompanied by C. rotundifolia L., occurs in two more sites in the Czech Republic but no hybrids have been found.

Valachovič M. & Janovicová K. (1999): Altitudinal differentiation of oligotrophic water-spring vegetation in Slovakia. – Thaiszia – J. Bot. 9: 49-62. – ISSN 1210-0420.
Abstract: The classification of spring plant communities occurring at low altitudes of Slovakia was made and compared with syntaxa described from neighbouring countries. All relevés were evaluated using their general ecological features (incl. content of silt, humidity, level of shade), vegetation structure, and floristical composition. We report on the occurrence of the Caricion remotae and two associations, such as the Caricetum remotae and Carici remotae-Calthetum laetae firstly from Slovakia.
Warcholińska U. (1999): Differentiation of Vicietum tetraspermae (Krusem. & Vlieg. 1939) Kornaś 1950 in Poland. – Thaiszia – J. Bot. 9: 63-72. – ISSN 1210-0420.
Abstract: Results of analysis of Vicietum tetraspermae differentiation in Poland are presented. Species richness and the structure of the communities of this association were determined on the basis of published materials and actual results of own investigations. Its phytosociological characteristics and conditions of occurrence are given. Moreover, the regional and local habitat variability as well as distribution and range of the association are presented.
Kakes P. & Hakvoort H. W. J. (1999): Aglycon specificity of the cyanogenic β-glucosidases of leaves of Trifolium species and Cassava (Manihot esculenta). – Thaiszia – J. Bot. 9: 73-80. – ISSN 1210-0420.
Abstract: The aglycon specificity of the cyanogenic β-glucosidases of Trifolium repens, Trifolium nigrescens and cassava (Manihot esculenta) towards their natural substrates linamarin and lotaustralin was studied. In cassava, a species in which linamarin predominates, both substrates are hydrolysed although the Km is slighty lower and the Vmax is higher for linamarin. The importance of this result for the determination of the cyanogenic potential in cassava is discussed. In the Trifolium species there is little difference in kinetic parameters, although the proportion of linamarin differs between the species. The Trifolium results are discussed in relation to the possible origin of the Li-gene in T. repens.
Zeidler M. (1999): Genetic variability among populations of Allium carinatum subsp. carinatum. – Thaiszia – J. Bot. 9: 81-90. – ISSN 1210-0420.
Abstract: The genetic diversity and genetic differentiation of ten picked native populations of endangered wild garlic Allium carinatum L. from the former Czechoslovakia area were studied by means of isozyme variation. The variability of six isozyme systems was tested (G-6-PDH, AAT, PGM, EST, ACP, PGI) by discontinuous polyacrylamide gel electrophoresis. The chosen species, A. carinatum subsp. carinatum, is triploid (2n = 24) with obligatory vegetative reproduction by bulbils. Tests of heredity by crossing-over are impossible and genetic variability is difficult to derive from isozyme patterns. For this reason the method of mixed phenotype analysis was applied. The dendrograms of dissimiliarity were constructed and low among-population variability reported. The low variability was disscused in terms of clonality, geographic shaping, distance, weak dispersion, fixed genotype and the action of somatic mutations.
Xifreda C. C., Argimón S. & Wulff A. F. (2000): Infraspecific characterization and chromosome numbers in Anredera cordifolia (Basellaceae). – Thaiszia – J. Bot.: 9(1999): 99-108. – ISSN 1210-0420.
Abstract: Two infraspecific taxa in Anredera cordifolia are cytotaxonomically studied: Anredera cordifolia (Ten.)Steen. subsp. cordifolia (2n=36) and A. cordifolia subsp. gracilis (Miers) Xifreda & Argimón (2n=24). Valuable characters to recognize it comprise vegetative morphology, occurrence of fruit with seed production, pollen grain sizes and exine sculpture, and ploidy level.
Marhold K. & Kit Tan (2000): The distribution of Cardamine matthioli (Brassicaceae) in Greece. – Thaiszia – J. Bot. 9(1999): 109-112. – ISSN 1210-0420.
Abstract: During a study of the Haussknecht Herbarium in Jena (JE) the voucher specimen, documenting the record of Cardamine pratensis L. by Haussknecht from Greece: Mts. Karava and Ghavellu (Voutsikaki), was located. The specimen is identified as C. matthioli Moretti and represents, together with another verified specimen from the vicinity of Megdova lake, the most southern limits of its distribution in Greece and the most southern occurrence for a member of the C. pratensis group in Europe. Some notes on other members of this complex in the southern part of the Balkan Peninsula are provided.
Oganesian M. (2000): Systematics of Campanula L. subgenus Scapiflorae (Boiss.) Ogan. and its ecogeographical differentiation in the mountains of Eurasia. – Thaiszia – J. Bot. 9(1999): 113-130. – ISSN 1210-0420.
Abstract: Synopsis of Campanula subg. Scapiflorae and maps of the areas of its species are given. The area of the group consists of 3 parts with large disjunctions: European (1 species), Caucasian and North-West Asian (16 species) and East Siberian – Far Eastern (3 species). In Caucasian and North-West Asian part 3 centers of development stand out: Central Caucasus, Northern Colchis and Armenian Highlands. The subgenus is represented by petrophytes growing almost exclusively in the alpine, subalpine and middle mountain belts in humid mountains and in accordance with boreal moisture regime. Hypothetical ancestor of the group is supposed to be a medium mountain belt petrophyte and evergreen mesophyte growing in a humid steady climate, in sunny shadeless places. The evolution was developing towards acquiring cryomorphic adaptations, and, in a number of cases, week xeromorphic ones. The subgenus must have been formed by the beginning of the possible migrations around the 3 parts of its area, i. e. by the beginning of Pliocene. The most possible primary center of the group is Armenian Highlands and the Great Caucasus.
Danilov R. A. & Ekelund N. G. A. (2000): Summer phytoplankton successions close to the shore in three brackish water bays on the East coast of Sweden (Gulf of Bothnia). – Thaiszia – J. Bot. 9(1999): 131-142. – ISSN 1210-0420.
Abstract:Three brackish water bays between Härnösand and Sundsvall on the East coast of Sweden (Gulf of Bothnia) were investigated between June and August 1998 in order to reveal summer phytoplankton dynamics close to the coast. All samples were collected at depth of 0,5 m. The results obtained show patterns in phytoplankton dynamics. In the spring Bacillariophyceae dominated, followed by an increase in Dinophyceae and small flagellates of Prasinophyceae and Cryptophyceae. Chlorophyceae were represented during the whole period of investigation especially with species of Monoraphidium, which often dominated or subdominated. In total 84 phytoplankton species were identified. Cluster analyses based on similarities in species’ diversity and their abundance made it easy to distinguish between the bays close to Härnösand and the Bay of Sundsvall. However, no clear differences were found between the sampling stations within the Bay of Sundsvall.
Ma J., Sun H. & Cao W. (2000): The Notes on the Collectors and Authors as well as location names related to the Dawn Redwood, Metasequoia glyptostroboides, after it’s been discovered almost sixty years from Central China (1941-2000). – Thaiszia – J. Bot. 9(1999): 143-147. – ISSN 1210-0420.
Abstract: The Dawn Redwood in English, Shuisha in Chinese, „Living Fossil“ in general favor, Metasequoia glyptostroboides in Latin, the scientific name, has been found almost sixty years from central China (1941-2000). The plant has been cultivated almost all over the world and has been apprised widely both from the professionals and amateurs. The related papers about its magic story of discoveries and scientific studies have been more than several dozens in the modern botanical/horticultural literatures. The Chinese collectors and location names, however, are not properly used in modern bibliographies, some at least not standard used, i.e. wrong used, and even again and again. The paper mainly deals with these wrong or not proper names, and especially from the historic view to correct them to the modern standard use. Besides these, the selected references on the Dawn Redwood are also provided here for the further interesting readers or researchers.
