Školek J. (2003): Geo rivali-Caricetum paniculatae ass. nova form the West Carpathians. – Thaiszia – J. Bot. 13: 31-66. – ISSN 1210-0420.
Abstract: By searching hydromorphis habitats throughout Upper Liptov (1996-2000), we focused vegetation types with Carex paniculata, not belonging to the association Caricetum paniculatae. The study resulted in the description of a new association Geo rivali-Caricetum paniculatae and subassociations typicum and valerianetosum simplicifoliae (Calthion, Molinio-Arrhenatheretea). All the relevés published from the West Carpathians were revalued from the point of view of the new association. The new association is characterized form ecological and coenological points of view. The differences compared to other communities dominated by Calex paniculata and C. appropinguata are discussed.

Abstract: The four species of the genus Chesneya LINDL. ex ENDEL. recorded form Iran are described and a key to them presented. Each is compared to its closest ally and its geographical distribution given. Chesneya gaubaeana BORNM. is treated as synonym of C. parviflora JAUB. & SPACH. Seed testa morphology as seen under the scanning electron microscope is discussed and photomicrographs are provided. Chesneya and closely related genera such as Caragana FABR., Halimodendron FISCH. ex DC., Calophaca FISCH., and Gueldenstaedtia FISCH., are placed in the new tribe Caraganeae. The morphological data offer a novel hypothesis of tribal relationship for Galegeae group and suggest that tribe Caraganeae could well be treated as a distinct taxon.

Abstract: Phytosociological relevés of the Western Carpathian forest vegetation are being stored in the electronic database program TURBOVEG. At present, this database exists only in the Czech Republic and Slovakia as a part of the National Phytosociological Databases, but not in the other Western Carpathian countries. In January 2002, the database of the Western Carpathian forests contained 4740 relevés – 1673 from Czech Republic and 3067 from Slovakia. Some basic statistics of the vegetation-plot data are presented.

Barczi A. (2003): Data for the botanical and pedological surveys of the Hungarian kurgans (Great Hungarian Plain, Hortobágy). – Thaiszia – J. Bot. 13: 113-126. – ISSN 1210-0420.
Abstract: We undertook botanical and soil surveys on a mound called Csípő-halom (the Great Hungarian Plain). Alkaline and chernozem mosaics characterised the soil in the surrounding area of the mound and chernozem was typical of the top of the body of the mound. The floristic research can be well compared with the soil science examinations. The vast majority of species are weeds or species that tolerate disturbance well. Besides them we can find several plants belonging to the natural grassland associations as well. Among the dominant species, data on Festuca rupicola, F. valesiaca and Agropyron pectiniforme was previously published but only from one habitat from the area of Hortobágy. Despite its small territory it has a varied vegetation. Near the peak the Agropyro-Kochietum porostratae ZÓLYOMI 1958 association occurs. The larger part of the body of the mound is characterised by the dominant species of Poa angustifolia L. A subassociation of the silty grasslands, Festuca valesiaca also occurs wedged in the grass fields mentioned before. On the lower zone of the slope the contiguous association of the Salvio-Festucetum rupicolae (ZÓLYOMI 1958) SOÓ 1964 loess steppe areas can also be found, which is composed of Festuca javorkae besides the dominant F. rupicola. On the north-eastern side of the mound some discrete patches of the association Artemisio-Festucetum pseudovinae (MAGYAR 1928) SOÓ 1945 appear, which is typical of the surroundings of the mound.

Mikoláš V. (2003): Sorbus amici-petri, a new hybridogenous species of the genus Sorbus s.l. from eastern Slovakia.. – Thaiszia – J. Bot. 13: 127-133. – ISSN 1210-0420.
Abstract: Sorbus amici-petri sp. nov., a new hybridogenous species of the genus Sorbus s.l. that is probably a product of hybridization between S. torminalis and S. orbicularis ined. (= ? S. thaiszii), is described in the paper. It is a tetraploid species stabilized by means of apomixis. S. amici-petri is stenoendemic species growing in xerothermous vegetation of forest-steppe and hornbeam forests near Kysak, Trebejov and Obišovce villages, ca. 15 km N from the town of Košice in eastern Slovakia. The species is closer to S. orbicularis than S. torminalis and it is characteristic by whiter tomentose lower side of leaves that are broadly ovate to rhombic and red (orange) globose fruits. Supposal on the origin of S. dolomiticola as a hybridogenous species evolved from S. torminalis and S. cuneatifolia ined. (= ? S. javorkae), is given. A new combination S. apiculata (KOVANDA) MIKOLÁŠ is also proposed for diploid Bohemian S. danubialis in opposite to tetraploid S. danubialis confirmed for southern Moravia and eastern Slovakia.

Abstract: New classification of communities dominated by Calamagrostis arundinacea within the alliance Calamagrostion arundinaceae in Slovakia is presented. Syntaxonomical revision included relevés from mountain ranges Muránska planina, Malá Fatra, Veľká Fatra, Nízke Tatry, Belianske Tatry, and Bukovské vrchy. Authors described the new association Sileno vulgaris-Calamagrostietum arundinaceae with two subassociations: caricetosum tatrorum (KLIMENT 1995) comb. nov. and delphinietosum elati subass. nov. on the marl limestone of the Veľká Fatra Mts. (inclusive massif of Zvolen Mt.). Stands originally ordered into the association Senecioni fuchsii-Calamagrostietum arundinaceae were included into the association Digitali ambiguae-Calamagrostietum arundinaceae with the two subassociations: sedetosum carpaticae KLIMENT 1995 and luzuletosum sylvaticae subass. nov. Knowledge on distribution and differentiation of the other described communities with dominant species Calamagrostis arundinacea in Slovak part of the Carpathians are also specified.

Blažková D. & Březina S. (2003): Secondary succession in abandoned “poloniny” meadows, Bukovské vrchy Mts., Eastern Carpathians, Slovakia. – Thaiszia – J. Bot. 13: 159-207. – ISSN 1210-0420.
Abstract: Secondary succession in abandoned “poloniny” meadows in the Bukovské vrchy Mts., NE Slovakia, was being observed for 30 years, between years 1969 and 1999. At the beginning of the study most of the meadows were still regularly harvested. There were recognized three phytosociological types of the meadows at this time: Campanulo abietinae-Nardetum and Acetoso-Deschampsietum at higher altitudes, and Betonico-Agrostietum at lower altitudes. After several years, when the utilization stopped, secondary succession went somewhat differently in the stands of the three plant associations. However, some general features of the succession of all three meadow types could be observed. The first successional changes usually became apparent about 1 to 3 years after the meadow abandonment. The first successional stage lasted for up to 7 years. It was characterized by relatively small changes in species composition and by conspicuous changes in quantitative proportions of individual species. Low-growing heliophytes decreased gradually and eventually disappeared, while the phytomass of taller species increased. The next successional stage started between 5 and 8 years and lasted until 15 to 25 years after the end of meadow harvesting. It was characterized by spreading of expansive species, mostly from neighboring stands. The most common expander was Calamagrostis arundinacea. At the same time, the number of species decreased: the still surviving low-growing species disappeared, followed by first species of medium stature. Woody plants became established only in few individuals, most of which did not survive for long. The following successional stage usually began between 25 and 35 years after the end of meadow harvesting, in some cases even later. It was characterized by the establishment, gradual increase, and eventual dominance of additional expansive species. At higher elevations (ass. Campanulo abietinae-Nardetum and Acetoso-Deschampsietum), the most important new expansive species was Rubus idaeus; other such species included Calamagrostis villosa, and Carex brizoides. During the stage with dominant Rubus idaeus, successional stands were gradually invaded by herbaceous forest species. The invasion of woody plants and of the forest will take place probably later, in the subsequent stages. At lower elevations (ass. Betonico-Agrostietum), forest species appeared earlier, especially in small meadows surrounded by forest.
