LOOS G. H. (1997): Contribution to a supraspecific structure of Ranunculus sect. Ranunculus. – Thaiszia - J. Bot. 7: 1-7. – ISSN 1210-0420.
Abstract: Ranunculus sect. Ranunculus (= sect. Auricomus (Spach) A. nyárády) is divided into two subsections: Subsect. Ranunculus (provisionally in a wider sense) and subsect. Cassubici G. H. Loos, subsect. nov., a relatively well-defined taxon. The traditional concept of Marklund (four elementary species with apomictic subspecies) cannot be accepted and has recently been rejected. Within the sect. Ranunculus, some of the “informal groups” may be regarded as series (analogically to the conditions in Rubus subgen. Rubus). The first series described are ser. Indecori G. H. LOOS, ser. nov. and ser. Phragmitetorum G. H. Loos, ser. nov.

KOVANDA M. (1997): Observations on Primula elatior in the High Sudeten Mts. – Thaiszia - J. Bot. 7: 17-28. – ISSN 1210-0420.
Abstract: The Western and Eastern Sudeten are known to differ considerably in the composition of their floras and striking dissimilarities can also be seen in the behaviour of some species that are common to both the mountain ranges. Primula elatior (L.) Hill, represented by subsp. elatior and subsp. tatrensis (Domin) Soó growing mixed together and intergrading with each other, is widespread and variable in the Eastern Sudeten but has failed to produce an endemic taxon, even though two of the populations are spatially isolated. On the other hand, in the Western Sudeten, P. elatior (L.) Hill subsp. elatior is only locally frequent but has given rise to an endemic taxon, var. corcontica Domin. Possible causes of this unusual situation are briefly considered. Based on an analysis of morphological characters and taking into account its allopatric distribution, a taxonomic reassessment in the rank of subspecies is proposed for var. corcontica Domin. Observations are also made on geographical distribution, ecology, phenology and biology.

ŠTĚPÁNKOVÁ J. (1997): The effect of serpentine on morphological variation in the Galium pumilum group (Rubiaceae). – Thaiszia - J. Bot. 7: 29-40. – ISSN 1210-0420.
Abstract: A total of 16 populations of taxa from the Galium pumilum group were examined for 14 morphological characters to asses the impact of serpentine habitats on their morphological variation. Univariate and multivariate statistical procedures were applied on a set of selected characters. The results of statistical analyses revealed notable differences in the morphology of serpentine and non-serpentine populations of G. pumilum. Significant differences were ascertained between a set of vegetative characters, while the variables of the generative parts of the plants showed conspicuous similarities. However, the ranges of variability in all the morphological characters of both ecotypes overlapped considerably. In contrast, serpentine populations of G. valdepilosum are not markedly different from non-serpentine ones. In G. valdepilosum, there are less contrasting characters of some environmental factors acting on serpentine and non-serpentine sites. This fact could be responsible for the morphological similarities among populations of G. valdepilosum. Both investigated taxa could be included within the group of species which are tolerant of ultramafic soil. As serpentine populations of G. pumilum show specific ecotypic responses to serpentine soil, the results of both karyological and morphological analyses indicate that serpentine and non-serpentine populations are probably not genetically isolated from each other.

MIKOLÁŠ V. (1997): Microrrhinum litorale (Bernh. ex Willd.) Speta, a new species in the flora of Slovakia and Czech Republic. – Thaiszia - J. Bot. 7: 41-50. – ISSN 1210-0420.
Abstract: Microrrhinum litorale found in anthropogenous stands in Žilina and Třinec is described. The species is in comparation with somewhat similar M. minus conspicuous by bigger, more intensively coloured petals, broader leaves and bigger fruits and seeds. In addition to description of the species the paper gives short discussion on problem of Microrrhinum genus and related genera. Brief account of taxonomic problems in M. litorale agg. and its general distribution is given. Karyological analysis of a sample confirmed hexaploid ploidy level of the species. It is not possible to exclude that M. litorale is more frequent synanthropic species in all the central Europe (and perhaps in southern Europe, too), but has been neglected so far.

KOVÁŘ P. (1997): Biodiversity of hedgerows surrounding a point source of nitrogen pollution (Wensleydale, Northern England). – Thaiszia - J. Bot. 7: 65-73. – ISSN 1210-0420.
Abstract: Hedgerows studied in Wensleydale (Northern England) play an important role in the landscape in filtering acid pollutants including N compounds. Simultaneously, they serve as a captivity storage for N in this type of (agricultural) landscape. The biodiversity of the hedge herb layer shows a clear dependence on the distance from the N source. Hedge orientation and the nature of the adjacent patches (field or a pasture - etc.) had a much lesser effect. Three types of herb stands were distinguished - the first without any distinct dominant (with the highest index of diversity), the second with a “shade-tolerant” dominant and the third with a “light-tolerant” dominant (with the lowest index of diversity).

MURÍN A. (1997): Karyotaxonomy of some medicinal and aromatic plants. – Thaiszia - J. Bot. 7: 75-88. – ISSN 1210-0420.
Abstract: The present paper deals with chromosome numbers of some medicinal and aromatic plants that are cultivated in Slovakia. Some of them might originate from Slovakian wild flora, while some of them belong to introduced and already cultivated plants in other countries. They are as follows: Achillea millefolium 2n=81±5, Agrimonia eupatoria 2n=28, A.grandis 2n=42, Artemisia absinthium 2n=18, A. dracunculus 2n=90, Calendula officinalis 2n=32, Chamomilla recutita 2n=18, Datura stramonium 2n=24, Digitalis lanata 2n=56, D.purpurea 2n=56, Echinacea pallida 2n=44, E.purpurea 2n=22, Foeniculum vulgare 2n=22, Galega officinalis 2n=16, Hypericum perforatum 2n=32, Lavandula officinalis 2n=54, Hyssopus officinalis 2n=12, Leonurus cardiaca 2n=18, Levisticum officinale 2n=22, Malva mauritiana 2n=42, Melissa officinalis 2n=32, Marrubium vulgare 2n=34, Mentha spicata 2n=48, Ocimum basilicum 2n=48, Papaver somniferum 2n=22, Plantago lanceolata 2n=12 & 24, Rhaponticum orientale 2n=24, Salvia officinalis 2n=14, S.sclarea 2n=22, Saponaria officinalis 2n=28, Satureja montana 2n=30, Thymus vulgaris 2n=30, Valeriana angustifolia 2n=28, Verbascum densiflorum 2n=36.

Abstract: The genus Thymus in Carpathians and Pannonia is represented by 11 species (two of which are divided in two subspecies). In the paper the survey of the taxa with their synonymy is presented. Altogether 279 taxonomic synonyms, 382 nomenclatural synonyms and 358 invalid names, combinations and misidentifications are listed. At the same time 79 lectotypifications of names, among the others Thymus carpathicus Čelak. and Thymus montanus Waldst. et Kit. are given. The paper is completed by citations of exsicates and drawings as well as by 11 nomenclatural notes and a new combination - Thymus pulcherrimus subsp. carpathicus (Čelak.) Mártonfi.

RUŽICA I., VUČKOVIĆ M., STOJANOVIĆ S., BUDAK V. (1997): Chorological, coenological and ecological characteristics of Trifolium diffusum Ehrh. in Vojvodina. – Thaiszia - J. Bot. 7: 183-189. – ISSN 1210-0420.
Abstract: The species Trifolium diffusum Ehrh. has been recorded only at one locality in Vojvodina in the Fruška gora so far. Occurrence of this species at the northern slopes of the Titel Plateau completes its global distribution in this region. Phytocoenological records of stands with Trifolium diffusum point to the fact that they represent the stands of relict association Agropyro-Kochietum prostratae Zólyomi 1958. This association is characterized not only by steppe, but also semidesert features. It develops on sloping, convex, higher parts of Titel plateau. According to the biological spectrum, the stands in which Trifolium diffusum grows are of thero-hemicryptophytic character while in spectrum of geographical elements of flora of the Pontic-Central Asian group dominate.
