                        Cyanobacteria and algae of the gravel-pit lake Kuchajda in Bratislava
Phytoplankton assemblages of the gravel-pit lake Kuchajda in Bratislava, W Slovakia, were studied from spring to autumn in 1999. Altogether 13 taxa of Cyanobacteria and 186 taxa of different groups of microscopic algae were determined. One species of Cyanobacteria (Microcystis botrys Teiling) and six taxa of Bacillariophyceae [Cyclotella praetermissa Lund, C. stelligeroides Hust., Melosira nummuloides (Dillwyn) C. Agardh, Amphipleura rutilans (Trentepohl) Cleve, Fragilaria construens f. subsalina (Hust.) Hust., Nitzschia angustatula (Lange-Bert) Hust.] are first records for the territory of the Slovak Republic. Planktic cyanobacterial water bloom occurring from July to September was formed mainly by species of the genus Microcystis (M. aeruginosa, M. botrys, M. wesenbergii).

                        Micromycetes of the family Erysiphaceae in the low part of Morava Floodplain Area
Powdery mildews (Erysiphales) and their host plants were studied for the first time in the lower part of Morava river floodplain area southward from Vysoká pri Morave to the confluence of the Morava and Danube rivers from 1996 to 1998. This territory along the Slovak-Austrian border strictly protected for half a century was included among those under Ramsar Convention. It is a part of the Protected Landscape Area Záhorie and of Protected Area-to-be Devín alluvium of the river Morava. Despite extensive floods during two vegetation periods in June 1996 and July 1997 we found 10 species of the family Erysiphaceae belonging to 4 genera (Sphaerotheca, Erysiphe, Blumeria, Sawadaia) on 12 species of host plants, belonging to 12 genera and 9 families. There are the first datas from this area. Erysiphe orontii parasitising on Echinocystis lobata were recorded in Slovakia for the first time.

New and confirmed findings of some rare and vanishing vascular plant species in the Krivánska and Lúčanská Malá Fatra Mts
The flora and vegetation of the Krivánska and Lúčanská Malá Fatra Mts have been receiving continuous attention of researchers since the beginning of 19th century. We contribute this remarkable body of botanical evidence either by some new findings (viz Carex capillaris, C. atrata, Salix retusa, Blechnum spicant, Sorbus margittaiana, Tozzia carpathica and Epilobium nutans) or by attempt to confirm some earlier records. We have succeeded in case of Diphasiastrum alpinum, Vaccinium uliginosum and Empetrum nigrum, but failed in case of earlier data on Carex capillaris (probably misidentifications), Saxifraga androsacea, S. carpatica, S. oppositifolia and Oxycoccus palustris (the site probably destroyed during construction of telecommunication infrastructure).

 Density changes of Jurinea mollis Rchb., Adonis vernalis L. and some
other species in the permanent plot in the Nature Reserve Lupka in years 1981-1999
                        
                        Density changes of Jurinea mollis Rchb., Adonis vernalis L. and some
other species in the permanent plot in the Nature Reserve Lupka in years 1981-1999
Changes in abundance of species Jurinea mollis, Adonis vernalis, Onosma visiannii, Orobanche gracilis, Eryngium campestre, Fraxinus ornus, Crataegus monogyna, and Rosa sp. were recorded in the Nature Reserve Lupka (Nitra, SW Slovakia) in the permanent plot 4´ 4 m during years 1981-85, 1989-90, 1997-99. Number of individuals of Jurinea mollis had decreased significantly in years 1981-84 and now oscillate around 18% of number in year 1981. The highest number of individuals of Adonis vernalis was recorded in 1983, than deep decrease followed and now it varies between 15 and 37% of the maximum from year 1983. Onosma visianii was rare and not recorded every year. Possible reasons of considerable decrease of Jurinea mollis and Adonis vernalis during monitoring period, e. g. ecosystem processes as succession reflecting in changes of community structure and competition ability of species or antropogenous factors (perhaps air pollution), are discussed. Climatic factors could be excluded.

Phytocoenological relevés from the 2-3 km wide area covering both sides of the road connecting Moravský Svätý Ján and the state border with Austria as well as species ?-diversity indices are presented. Further monitoring and total protection of the area is suggested.
 Notes to the occurrence and coenology of two species of the genus Montia in
Slovakia
                        
                        Notes to the occurrence and coenology of two species of the genus Montia in
Slovakia
The Montia species represent some of the most subatlantic elements in Slovak flora. In Central Europe they are very rare and only M. fontana agg. and M. arvensis were provable found in western part of Slovakia. The paper presents first published phytosociological relevés in Slovakia for both taxa and thus documents new information on ecology and coenology of the species on the edge of their areas in Europe.

                        Phytocoenological variability of Leersia oryzoides (L.) Sw. in Slovakia
Phytocoenological connections of the non-frequent species of Slovak flora Leersia oryzoides (L.) Sw. were analysed at 35 relevés from all Slovakia. Two coenological optima were distinguished: 1. Bidenti-Leersietum oryzoides Poli et J. Tx. 1960 (alliance Bidention tripartiti) and 2. Leersietum oryzoidis Eggler 1933 (alliance Glycerio-Sparganion). L. oryzoides has reached the highest constancy and dominance just in these associations. It occurs with lower abundance also in various communities of classes Phragmito-Magnocaricetea, Isoëto-Nanojuncetea and Bidentetea tripartiti. Syntaxonomical position of ass. Leersietum oryzoidis Eggler 1933 is discussed. Ass. Bidenti-Leersietum Poli et J. Tx. 1960 is neotypified.

Syntaxonomic and synecological characteristics of two plant communities of the class Phragmito-Magnocaricetea - Caricetum melanostachyae and Caricetum buekii are presented. Synchorology in Slovakia and neighbouring countries, syndynamics and threat of the above mentioned plant communities are discussed. Caricetum melanostachyae, rare marsh plant community in Slovakia, was recorded in the Východoslovenská níina lowland up to now. It is documented by seven phytosociological relevés from the Ipežská and Lučenská kotlina basins. Caricetum buekii was mentioned from the catchment of the Ipež river and the northern part of the Orava region. We investigated this community in six orographical regions in the southern part of Central Slovakia in 1997-1999. Caricetum buekii is documented by forty-two phytosociological relevés. Relatively small species diversity of the studied community is also demonstrated. Results of analyses of selected environmental factors are presented for Caricetum buekii at a single locality near Lieskovec village.
 Forgotten florist Ján Kristián Flittner from Liptovský Mikuláš
                        
Forgotten florist Ján Kristián Flittner from Liptovský Mikuláš
A head physician of the county Liptovská stolica in 1812-1846 Dr. J. K. Flittner was interested also in floristics. This is confirmed by his marginals (additions to distribution of 28 vascular plants in Northern Slovakia, among them the first finding of Andromeda polifolia) in his own item of Wahlenberg´s Flora Carpatorum.... These remarks, copied by V. Greschik, are deposited in the Institute of Botany, Slovak Academy of Sciences.
 The flora of Bratislava two centuries after publication of Lumnitzer´s work
Flora Posoniensis
                        
                        The flora of Bratislava two centuries after publication of Lumnitzer´s work
Flora Posoniensis
Lumnitzer´s Flora Posoniensis (1791) was the first published complex flora of Bratislava containing up to 80% of recently known taxa of higher plants. In 544 cases Lumnitzer stated also concrete localities. This enabled comparison of the state of the flora of Bratislava in 18th century with the present one. A special attention was laid on taxa rare and endangered in Bratislava nowadays and data demonstrating different state of related localities in the past. A reconstruction of the historical state of biotopes was attempted in two localities on the southern spurs of the Malé Karpaty (Small Carpathians) Mts at the outskirts of the central part of the city: Mt. Kalvária (Calvary) and under Púčkove domy. Several interesting Lumnitzer´s data were nomenclatorically and topographically actualized and commented. Some taxa should be included in the red list of the flora of Bratislava.
