ABSTRACT: Nineteen species of the genus Silene L. s.l. from Southern Transcaucasia have been karyologically studied. For three species the first count is reported. Idiogram of the species Melandrium latifolium (POIR.) MAIRE has been constructed, with a pair of sex chromosomes indicated.
ROSTANSKI K. (1995): The occurrence of the Oenothera species in the Polish and Czech Sudetes and in the Polish and Slovak Carpathians. - Thaiszia - J. Bot., Košice, 5: 21-25. – ISSN 1210-0420.
ABSTRACT: The paper presents high altitude localities of 9 Oenothera species (Oenothera perennis L., Oe. biennis L., Oe. rubricaulis KLEB., Oe. salicifolia DESF. ex G. DON, Oe. erythrosepala BORB., Oe. fallax RENNER em. ROSTANSKI, Oe. acutifolia ROSTANSKI, Oe. pycnocarpa ATK. et BARTL. and Oe. subterminalis GATES) recorded in the Polish and Czech parts of the Sudetes and in the Polish and Slovak Carpathians.
SUDHAKARAN S., VAIDYANATHAN R. & GANAPATHI A. (1995): Microsporogenesis in a mangrove plant Rhizophora mucronata LAM. - Thaiszia -J. Bot., Košice, 5: 27-30. – ISSN 1210-0420.
ABSTRACT: Microsporogenesis of Rhizophora mucronata LAM. has been studied. Even though developmental aspects are of conventional type, there are some specific characters like the multisporangiate anther, discontinuous archesporial cells, common multilayered endothecium, triplet origin of the tapetum and the lateral dehiscence of anther. The liberation of tri-colporate, uninucleate, subprolate pollen grains in a large number through the lateral openings is also noticed.

ABSTRACT: The first part of the results of phytocoenological study of ruderal vegetation in north-eastern Slovakia is presented. 23 associations and communities of classes Artemisietea vulgaris,Galio-Urticetea, and Bidentetea tripartiti are briefly characterized from the point of view of floristic composition, ecological conditions, and distribution in the territory studied. Phytocoenological tables of these syntaxa are added.

ABSTRACT: The second part of the results of phytocoenological study of ruderal vegetation in the north-eastern Slovakia is presented. 15 associations and communities of classes Chenopodietea and Plantaginetea are briefly characterized from the point of view of floristic composition, ecological conditions, and distribution in the territory studied. Phytocoenological tables of these syntaxa are added.

ABSTRACT: Results of the analysis of differentiation of Arnoserido-Scleranthetum annui in Poland are presented. Species richness and the structure of communities of this association were stated on the basis of the published material and field observations. Its phytosociological characteristics and conditions of occurrence are given. Moreover, regional and local habitat variability as well as distribution range of the association are presented. – ISSN 1210-0420.
CHRTEK J. & SÁDLO J. (1996): A new subspecies of Parietaria judaica from Syria. - Thaiszia - J. Bot., Košice, 5: 105-109. – ISSN 1210-0420.
ABSTRACT: Parietaria judaica subsp. speluncarum is newly described from Jebel Samakah Mts., western Syria. Notes on the remarkable ecology of the new taxon and on the variability of P. judaica agg. are given.
IRUDAYARAJ V., MANICKAM V. S. & DOMINIC RAJKUMAR S. (1996): Studies on intraspecific variation in south Indian ferns III. Cytomorphology of Stegnogramma pozoi (LAG.) K. IWATS. - Thaiszia - J. Bot., Košice, 5: 111-119. – ISSN 1210-0420.
ABSTRACT: Stegnogramma pozoi (LAG.) K. IWATS. from the Nilgiris, (from where Gymnogramma totta var. mollissima KUNZE had been described) is tetraploid (n=72), which corresponds to the report from Madeira. Morphological analysis of 27 gatherings of S. pozoi (LAG.) K. IWATS. from south India showed that they are variable in many characters. The south Indian plants, including those from the Nilgiris, do not match any intraspecific taxon of previous reports due to the presence of continuous variation among individuals. It is suggested that an intraspecific division within this species is of no practical value.
KOLBEK J. & DOSTÁLEK J. (1996): Vegetation of water basins in the northern part of the Korean Peninsula. - Thaiszia - J. Bot., Košice, 5: 121-130. – ISSN 1210-0420.
ABSTRACT: Newly described are plant communities of water basins dominated by Azolla pinnata (Lemno paucicostatae-Azollaetum pinnatae ass. nova) and Eichhornia crassipes (Lemna paucicostata-Eichhornia crassipes community) as well as a group of communities in which Nelumbo nucifera predominates. In the latter group four clear-cut communities were distinguished: Bidenti tripartitae-Nelumbetum nuciferae ass. nova, Ceratophyllo demersi-Nelumbetum nuciferae ass. nova, Monochorio plantagineae-Nelumbetum nuciferae ass. nova, and Myriophyllo spicati-Nelumbetum nuciferae ass. nova. Phytosociological system of water basins communities of East Asia is presented.
VALACHOVIČ M. (1996): The role of cryptogams in differentiation of plant communities on the shady rocks in Western Carpathians. - Thaiszia - J. Bot., Košice, 5: 131-152. – ISSN 1210-0420.
ABSTRACT: On the basis of the example of two pioneer communities from the shady calcareous and silicate rocks (Ctenidio-Polypodietum and Hypno-Polypodietum) the function of cryptogams in the differentiation of the vegetation types is discussed. The species composition of these communities is very similar to the associations which were formerly described (Cystopteridetum fragilis and Asplenio-Polypodietum). The results of the TWINSPAN classification of relevés with all species (A) and relevés without cryptograms (B) are compared. Similarities among communities are interpreted with regard to sampling methods, richness of lichens and mosses with low constancy (I-II), and various habitat.
FAJVUŠ G. M. (1996): On the origin of mountain steppes of Armenia. - Thaiszia - J. Bot., Košice, 5: 153-158. – ISSN 1210-0420.
ABSTRACT: A history of steppes of Armenia is given in the paper. On the base of literature data and results of investigations of Armenian steppe flora and vegetation the time and place of their origin are proposed and the ways of their development are outlined.
RATYNSKA H. & SZWED W. (1996): Vegetation of forest islands in the agricultural landscape near Poznañ (West-Central Poland). - Thaiszia - J. Bot., Košice, 5: 159-171. – ISSN 1210-0420.
ABSTRACT: The studies were carried out in different types of forest islands in the agricultural landscape North-East of Poznañ (West-Central Poland). In the investigated patches of forest islands 58 plant communities were identified. From 8 to 45 phytocenoses were found in each plot, depending on its habitat diversity, genesis, macrorelief, development, size and direct neighbourhood.
