Abstract: The foliar epidermal studies were carried out on Andropogon gayanus and Andropogon tectorum with the aim of determining the patterns of variation in their epidermal characteristics and assessing their value in species identification and classification. Adaptive and endemic characters that may be useful in the identification of the savanna species (A. gayanus) are long cells longer in length and width; short cells longer in length and width; micro hair longer in length and width; straight anticlinal wall. Typical characters of the genus are important in the identification and classification of the genus; these are cell wall largely thick and straight, stomata amphistomatic, papillae largely numerous and uniform in size.

Namin H. H., Mehrvarz S. S. & Zarre S. (2009): Scape anatomy of Allium (Alliaceae) in Iran and its systematic application. – Thaiszia – J. Bot. 19: 37-45. – ISSN 1210-0420.

Abstract: Cross section of scapes in 20 Allium species representing 6 subgenera and 12 sections were investigated. The following characters were determined to be informative: the cross section shape and diameter, number of vascular bundles and vascular bundles diameter. The cross section shape in the members of subgenera Allium, Cepa, Reticulatobulbosa and Polyprason is circular whereas in the members of subgen. Melanocrommyum and A. paradoxum (subgen. Amerallium) the cross sections are ellipse and triangular, respectively. Our results show that scape anatomical studies on Allium are useful in circumscribing the species and in the subgeneric classification of the genus.

Kundu S. R. (2009): A synopsis on distribution and endemism of Magnoliaceae s.l. in Indian Subcontinent. – Thaiszia – J. Bot. 19: 47-60. – ISSN 1210-0420.

Abstract: The members of the family Magnoliaceae s.l. are distributed mostly in (approximately four-fifths of total taxa) warm temperate and tropical region of East Asia, South-East Asia and the remaining one-fifth are found in Eastern Himalayas, South-Eastern part of North-America, West Indies, and Central America. A preliminary checklist of Magnoliaceae s.l. (comprinsing of the families: Magnoliaceae S. Str., Illiciaceae A. C. Sm. and Schisandraceae Bl.) in Indian subcontinent has been prepared on the basis of primary observations of different taxa belonging to this family in wild habitats and on secondary observations based on examining herbarium specimens and taxonomic literature. In comparison to global representation, in the Indian subcontinent (comprising Bangladesh, Bhutan, Myanmar, Nepal, Pakistan, Sri Lanka and India), the family Magnoliaceae is poorly represented (15.22%). The present paper deals with distribution, phytoendemism, possible fossil ancestry, potential, survival threat on existing taxa, etc. of Magnoliaceae in Indian subcontinent. For better understanding of the species dynamics of Magnoliaceae in Indian subcontinent, the present status of phytoendemism has been compared to the data of previous investigations done in nineteenth century.

Dítě D., Eliáš P. jun. & Šuvada R. (2009): The current distribution and status of community Puccinellietum limosae in Slovakia. – Thaiszia – J. Bot. 19: 63-70. – ISSN 1210-0420.

Abstract: Community Puccinellietum limosae, characteristic by dominant occurrence of Puccinellia species, has developed on flat plots of alkali soils. Twelve localities with this community were documented by phytosociological relevés in Slovakia until 1970s. During field survey of Slovak saline habitats in 2003 – 2008 we found no typical vegetation of this association. Plants of Puccinellia distans agg. occur frequently on all remains of saline habitats, but they are fixed on different plant communities, which are also often modified and degraded. Vegetation most similar to association Puccinellietum limosae was found on damaged (tilth and subsequently abandoned) salt meadows on two localities near the villages of Kráľová nad Váhom and Nová Stráž. Management to preserve or improve these saline habitats is lacking, therefore the habitats are changing gradually and ruderal species are invading there from surrounding agricultural fields. We may conclude that association Puccinellietum limosae is critically endangered in Slovakia now.

Hrivnák R. & Csiky J. (2009): Aquatic and marsh plant communities of the Cerová vrchovina Mts. (Slovakia), the Karancs and Medves Regions (Hungary). – Thaiszia – J. Bot. 19: 71-89. – ISSN 1210-0420.

Abstract: Aquatic and marsh vegetation was studied in the Cerová vrchovina Mts., Karancs and Medves Regions during vegetation seasons of 1997–2006 using traditional Zürich-Montpellier approach. Aquatic vegetation is relatively rare and only 3 plant communities from the Charetea fragilis, 2 from the Lemnetea and 4 from the Potametea were found. On the other hand, marsh vegetation (Phagmito-Magnocaricetea) is documented by 18 plant communities. The Callitriche cophocarpa comm. and Phragmitetum vulgaris, Typhetum latifoliae, Caricetum acutiformis, Glycerietum nemoralis-plicatae are the most frequently occurring communities of aquatic and marsh vegetation, respectively. Phytosociological relevés of Glycerietum nemoralis-plicatae are first time published from Hungary.

Medvecká J., Zaliberová M. & Jarolímek I. (2009): Ruderal Vegetation of the Horná Orava Region 1. Bidentetea tripartitae, Polygono arenastri–Poetea annuae, Molinio–Arrhenatheretea, Stellarietea mediae and Artemisietea vulgaris. – Thaiszia – J. Bot. 19: 91-129. – ISSN 1210-0420.

Abstract: First part of results of research on ruderal vegetation of the Horná Orava region, located on the northern border of Slovak Republic, is being summarised, namely classes Bidentetea tripartitae, Polygono arenastri–Poetea annuae, Molinio–Arrhenatheretea, Stellarietea mediae and Artemisietea vulgaris. Research started at 80s of 20^th century and ended recently. In total twenty associations and seven communities have been recorded. Based on phytoceonological tables, their characteristics, floristic composition, ecological conditions, distribution and comparison to data, published from southern regions of Slovakia, are presented. In general, communities lacked many xerothermophilous species found in the South of Slovakia and instead mesophilous species were more represented.

Studnička M. (2009): Brazilian bladderwort Utricularia reniformis is a blend of two species. – Thaiszia – J. Bot. 19: 131-143. – ISSN 1210-0420.

Abstract: A new species from south-eastern Brazil similar to Utricularia reniformis Saint-Hilaire is described, but with a different seed shape, completely different manner of germination, bladder morphology and other attributes. This species is well-known, but it is not differentiated. Initially, the ontogeny of the actual U. reniformis is described, i.e. plants corresponding to the nomenclatural type.

Kropáč Z. & Mochnacký S. (2009): Contribution to the segetal communities of Slovakia. – Thaiszia – J. Bot. 19: 145-211. – ISSN 1210-0420.

Abstract: An addition to the published synthesis of Slovak segetal vegetation is presented on the basis of unpublished relevés. Mostly are concerned the variability and distribution of known syntaxa. Nevertheless, several new findings are given: one local association is published as a new for science (Misopato-Galietum parisiensis), two associations are new for Slovakia (Aethuso cynapium-Galeopsietum tetrahit assigned to Sherardion and Holco-Galeopsietum tetrahit assigned to Scleranthion annui). Moreover, three new subassociations are published (Euphorbio exiguae-Melandrietumnoctiflori misopatetosum, Misopato-Galeopsietum ladanum consolidetosum, Aethuso-Galeopsietum tetrahit lathyretosum tuberosi).

Concept of two associations of the earlier synthesis is rather amended (Euphorbio exiguae-Melandrietum noctiflori, Misopato- Galeopsietum ladanum) and one association is cancelled (Consolido regalis-Misopatetum). Special attention is paid to the concept of Caucalidion and Sherardion (altogether 45 syntaxa published all over the Central Europe are compared in an overview).

Mistríková I., Vaverková Š. & Hollá M. (2009): Variation of Essential Oils in Selected Species of the Genus Echinacea Moench During Vegetation. – Thaiszia – J. Bot. 19: 213-219. – ISSN 1210-0420.

Abstract: We have investigated the variation of essential oils in selected Echinacea species during the ontogenetic life of plants cultivated in three different locations. The contents of essential oil in the aerial and underground parts varied. The leaves and stems of E. purpurea were richer in essential oil, while E. sanguinea and E. species had relatively high essential oil contents in roots in the stage of biological maturity or in the prebud stage. With respect to climatic conditions, no significant differences in essential oil contents have been observed between particular locations.
