Bacigálová K. (2004): Contribution to the knowledge of the Protomycetaceae in Slovakia. – Thaiszia – J. Bot. 14: 1-22. – ISSN 1210-0420.
Abstract: The phytopathogenic fungi of the genera Protomyces and Protomycopsis (Archiascomycetes) are included in the present paper. They are biotrophic on leaves and stems, usually gall-forming. Mycelium is apparently diploid, grows intercellularly, forms thick-walled smooth or ornamented “resting-spores” - ascogenous cells. Detailed symptoms of descriptions on the hosts, anatomical-morphological and biometric characteristics of ascogenous cells, nomenclature, chorological data and notes on the ecology of the three taxa of Protomyces and two of Protomycopsis, associated with 10 taxa of vascular plants - Protomyces macrosporus (6); Protomyces pachydermus (1), Protomyces kriegerianus (1); Protomycopsis leontodontis (1), Protomycopsis leucanthemi (1) - are given as well. The new host-fungus combination and new locations of fungi specimens and their host plants in Slovakia are published.

Ma J. S., Huang Y. P., Pu Y. H., & Fan S. H. (2004): Today's Hometown of Metasequoia – Lichuan, Hubei, China. – Thaiszia – J. Bot. 14: 23-36. – ISSN 1210-0420.
Abstract: After sixty years of the discovery of the "Living Fossil", Metaseuqoia glyptostroboides, from China, the news of her mystery story is still sparking the readers worldwide. However, for various reasons, the hometown of Metasequoia has not been visited for most of readers, even after Chinese government has opened it's door to botanizing since 1980s; and more important, the current situation of this mystery tree in there are still not known well today. Here we present you detailed information on the hometown of the "Living Fossil" with it's various resources of geography, weather, forests, vegetation, species, Metasequoia native trees as well as protection state as well as the travel information first time in the natural history of Metasequoia.

Vašut R. J. & Trávníček B. (2004): Taraxacum princeps sp. nova, a new species of section Erythrosperma from Central Europe. – Thaiszia – J. Bot. 14: 37-46. – ISSN 1210-0420.
Abstract: A new Taraxacum microspecies of section Erythrosperma, Taraxacum princeps, is described here. The species is a triploid apomict, which is distributed in SE part of Central Europe. Most of known localities are situated in SW Moravia (Czechia). Specific characteristics, notes on ecology and distribution (including dot maps and images of the species) and comparison with similar taxa (T. isophyllum and T. chelelobatum) are given and the relation between T. princeps and T. magnolevigatum and its nomenclature is discussed.

Slobodník B. (2004): In vitro germination dynamics of the common yew (Taxus baccata L.) pollen from an autochthonous stand and urban habitats. – Thaiszia – J. Bot. 14: 47-57. – ISSN 1210-0420.
Abstract: In 2000 and 2001, in vitro pollen viability tests were carried out for common yew (Taxus baccata L.) from one point of its natural occurrence (State Nature Reserve Plavno, Slovak Ore Mts., samples marked as PL) and two urban habitats in Zvolen (Central Slovakia) – a park in the downtown (samples marked as ZV) and Borová hora Arboretum (ABH) in the outskirts. The process of the cultivation of pollen can be divided into three essential phases: (1) pollen imbibition and loss of exine; (2) elongation of male gametophyte and (3) development of pollen tube. Concerning the irregular pollen tube formation under in vitro conditions, however, both elongated and germinating pollen grains were considered viable. According to this criterion, the mean estimated viability of the pollen from the “worst” locality (center of Zvolen) was half lower compared to the arboretum, regarded as the “best” one. Using the Duncan’s multiple range test, the ascertained differences between the samples from the “best” and the “worst” locality were statistically significant at a = 0.05.

Ložiene K. & Mártonfiová L. (2004): Thymus chromosome numbers from Lithuania. – Thaiszia – J. Bot. 14: 63-73. – ISSN 1210-0420.
Abstract: The present study gives the chromosome numbers of two species of the genus Thymus L. and their hybrid occurring in Lithuania: Thymus serpyllum L. 2n=24, T. pulegioides L. 2n=28 and T. x oblongifolius OPIZ 2n=26. Both species and the hybrid had one or two supernumerary B-chromosomes. Two chromosomes in some investigated T. pulegioides plants had unstable satellites. The chromosome number 2n=56 observed in some T. pulegioides seedlings demonstrate proper polyploidization in this species.

Ružičková H. (2004): Crepido mollis-Agrostietum ass. nova and Poo-Trisetetum KNAPP ex OBERD. 1957 - grassland associations in the NE part of the Nízke Tatry Mts. and their present species composition as the consequence of changes in grassland utilization. – Thaiszia – J. Bot. 14: 75-92. – ISSN 1210-0420.
Abstract: Especially terraces were characteristics for the surroundings of Liptovská Teplička (village). Grasslands occurred mainly in the alluvium of streams and on remote mountain ridges. They mostly were typical grasslands with little timber barns. As the consequence of collectivization of agricultural production the management on grasslands totally changed after 1975. Mountain meadows have been changed to intensive pastures, after recultivation a part of terrace fields changed to intensive grasslands, a part of them has been grassed. Grasslands on grassed fields and recultivated areas belong to the association Poo-Trisetetum, for the rest of semi-natural grasslands was described a new association Crepido mollis-Agrostietum with two subassociations. It is a species-rich association endangered especially by a stop in utilization. Long-term extensively grazed or unutilized grasslands here belong to alliances Polygalo-Cynosurenion, Nardo-Agrostion tenuis and Poion alpinae.

Kliment J., Jarolímek I., Šibík J. & Valachovič M. (2004): Syntaxonomy and nomenclature of the communities of the orders Calamagrostietalia villosae and Adenostyletalia in Slovakia. – Thaiszia – J. Bot. 14: 93-157. – ISSN 1210-0420.
Abstract: The most important results of the syntaxonomical revision of the communities of the orders Calamagrostietalia villosae and Adenostyletalia alliariae from the territory of Slovakia are presented: description of the new associations (Geranio robertiani-Delphinietum elati) and subassociations (Festuco picturatae-Calamagrostietum villosae typicum and crepidetosum conyzifoliae, Vaccinio myrtilli-Calamagrostietum villosae inops and avenuletosum versicoloris), re-evaluation of the syntaxonomical position of the associations (Petasito-Senecietum nemorensis HADAČ et al. 1969, Doronicetum austriaci HADAČ et al. 1969, Senecio-Adenostyletum alliariae HADAČ et al. 1969), resulting in the description of the new subassociations (Petasito kablikiani-Senecietum nemorensis doronicetosum austriaci and crepidetosum mollis), and in the change of the position of the alliance Delphinion elati HADAČ ex HADAČ et al. 1969 into the suballiance of the alliance Adenostylion alliariae. Authors suppose the new names for the associations Chaerophylletum cicutariae KRAJINA 1933 (Bryo pseudotriquetri-Chaerophylletum hirsuti), Calamagrostietum variae SILLINGER 1932 (Geranio sylvatici-Calamagrostietum variae) and Calamagrostietum variae carpaticum SILLINGER 1933 (Convallario majalis-Calamagrostietum variae). The subassociations Athyrietum alpestris HADAČ 1956 typicum W. MATUSZKIEWICZ et A. MATUSZKIEWICZ 1975 and A. a. deschampsietosum flexuosae W. MATUSZKIEWICZ et A. MATUSZKIEWICZ 1975 are ordered within the valid association name Adenostylo alliariae-Athyrietum alpestris (ZLATNÍK 1928) JENÍK 1961. Authors also call attention to the illegitimate typification of some names of associations and they supplement description of the less investigated communities.
