Abstract: The riverside flora of the basin of the Transcarpathia is characterized, in urbanized areas, by an impoverished species composition and noticeable presence of the allochtonous element. At present, the expansion of some ornamental alien species, such as taxa of the genus Helianthus, Echinocystis lobata (Michx.)Torr. et Gray, Reynoutria japonica Houtt., Impatiens glandulifera Royle is observed in the Tisa river basin. The genus Helianthus, represented by 7 species, is noticeably the most aggressive.

Abstract: By employing the UTM system (100×100 square meters expressed alphabetically and 10×10 square meters numerically), the distribution of the genus Oenothera L. in Serbia is presented on the basis of our own studies and both herbarium and literature data. Oe. biennis L. is the most frequent, then Oe. salicifolia Desf., whereas Oe. glazioviana Micheli and Oe. oakesiana (A. Gray) Robbins ex S. Wats et Coult are still rare species. Oe. glazioviana is recorded from two, while Oe. oakesiana from a one locality only.

Abstract: A study dealing with a discussion of the taxonomy and evolutionary trends within the Anemone biflora complex (Ranunculaceae, Anemone Sect. Anemone) distributed throughout Central and South-West Asia (mainly at the territory of the former Soviet Union - Tadjikistan, Uzbekistan, etc.). Anemone biflora and 10 segregate species were reevaluated, and on the basis of the critical morphological and anatomical analyses one subsection, three series and six species could be distinguished. Meanwhile, two species are regarded as varieties of A. biflora and three species names are recognized as synonyms only. A key to the representatives of this subsection is presented.

Abstract: The characters of fruit shape and anatomy are used to distinguish Bolboschoenus taxa occurring in Central Europe. Material from the Czech Republic, Slovakia, Hungary, Poland and Germany was studied. Plants from coastal regions of France and The Netherlands were compared with the inland taxa. Three taxa are recognized: non-saline Bolboschoenus maritimus subsp. maritimus in the sense of Central European authors (Casper & Krausch 1980), saline B. m. subsp. compactus (Hoffm.) Hejný and B. planiculmis sensu T. V. Egorova (non F. Schmidt).

Abstract: Consideration of the works of the Leipzig botanist, Wilhelm Petermann (1806-1855), shows that the correct authority for the oriental spruce is Picea orientalis (L.) Peterm. (1838-45), while two Indomalesian plant names are correctly Cayratia roxburghii Gagnep. (1911) and Knema glauca (Blume) Peterm. (1838-45).

Abstract: During a bryological trip to the Volovské vrchy Hills on September 23, 1997 the authors found some rare moss species belonging to the glacial relics - Meesia triquetra and Helodium blandowii. The latter was refound on the original habitat after being reported by Györffy in 1935.

Abstract: The article reports taxa new for the science and the flora of Bulgaria. Oenothera bulgarica sp. n. and Gagea villosa var. stenophylla var. n.are new for the science.

Lojac, Bellevalia sarmatica (Pall. ex Georgi) Woronow and Kickxia spuria (L.) Dumort. subsp. spuria. New chorological data are given for the remaining taxa.

KOVANDA M. (1998): Phyteuma orbiculare in the High Sudeten Mts.: past and present. – Thaiszia - J. Bot. 8: 129-136. – ISSN 1210-0420
Abstract: The history of the discovery of Phyteuma orbiculare L. in the Sudeten Mts. is outlined and the present state of the populations is described. Only old and poorly documented data are available from the Krkonoše Mts. (Western Sudeten), indicating that P. orbiculare L. once occurred there in two sites, Mt. Sněžka and the Velká kotelná jáma glacial cirque. None of the records has been confirmed in recent times. By contrast, two large populations thrive in the Hrubý Jeseník Mts. (Eastern Sudeten), at the Velká kotlina and the Malá kotlina glacial cirques. Field research has failed to substantiate the presence of P. orbiculare in the Králický Sněžník Mts. Evidence is presented that the Sudeten plants are referable to subsp. montanum R. Schulz. Their morphology, karyology, relationships, biology, ecology and phytocenological characteristics are briefly considered.

Abstract: The endemic Sorbus sudetica (Tausch) Bluff, Nees & Schauer is known to occur in four sites in the Bohemian Krkonoše Mts., but has only two old and vague reports [as S. aria (L.) Crantz] from the Polish Karkonosze Mts. A herbarium record made by Wettstein in 1897 (WU) has come to light documenting the occurrence of S. sudetica near the Mały Staw lake.

Abstract: Up to 960 seeds of Veronica officinalis, 131 seeds of V. chamaedrys, and 732 seeds of Agrostis capillaris were found in the upper 10 x 10 x 10 cm soil segments, and 770, 50 and 833 seeds, respectively, in the lower 10 x 10 x 20 cm segments sampled from the Tetramorium caespitum mounds at 950 m a.s.l. (formerly a hill pasture, Slovenske rudohorie Mts., Slovakia). The seed collecting activity of this ant species might help to explain the extremely low seed bank and seedling recruitments reported in the literature, especially of the Veronica species. In the field research, we should be aware of this phenomenon which is largely neglected in the temperate zone, and design the field work and experiments accordingly.

Abstract: Recent taxonomic studies revealed considerable morphological and karyological variation within Cardamine amara. In Central Europe and the Balkan Peninsula this species is represented by C. amara subsp. amara, C. amara subsp. opicii, C. amara subsp. balcanica (all diploid), and by the tetraploid C. amara subsp. austriaca. The present paper shows general pattern of vegetation types characterised by C. amara subspecies, using 247 relevés from the area studied, evaluated by the TWINSPAN program. Although (mostly) spring communities with different subspecies of C. amara are physiognomically similar, constant differences among communities in which different subspecies occur, where shown. Analysis of the phytocoenological data from the Bulgarian mountains lead to the description of new association.

TURCSÁNYI G. & ZAHEDI POUR H. (1998): Diversities of three differently used pastures in the Cserhát Mountains, Hungary. – Thaiszia – J. Bot. 8: 163-176. – ISSN 1210-0420
Abstract: Jákotpuszta is a so-called ethofarm in Hungary, and one of its aims is to help the investigation of the behaviour of sheep under environmentally sustainable conditions. The diversities of the plant communities of three differently used pastures (resting place, normally grazed pasture and site withdrawn from grazing several years before) belonging to this farm were compared with different methods in spring and autumn. In both seasons the diversity, the evenness and the species richness values were highest in the ungrazed site, whereas the values of the same characteristics were lowest in the resting place (overused site). The diversity values of the pooled samples always levelled off before reaching a total number of 50 quadrats (0.5 ´ 0.5 m squares), although the levelling off in the case of the species number was never reached with the same number of quadrats. Diversity ordering showed intersection between the diversity profiles of the pastures only in the case of the spring samples of the normally grazed and overused sites. In every case most diverse was the ungrazed pasture. Rank abundance plots clearly show that the decrease of diversity in the grazed sites was caused by the absence of several species with low dominance in the ungrazed site as well as by the dominance of some species tolerant of grazing, or, in the case of the resting place, presumably of trampling and increased urine as well as excrement content of the soil. On the basis of the results presented suggestions are made as to the necessary management practice of the pastures in order to maintain their sustainability in terms of diversity as well.
