<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">The paper discusses the phytosociological and syntaxonomical position of the dry subalpine grasslands in the Slavianka (Alibutoush, Orvilos) Mts. (South-Western Bulgaria, Northern Greece). A new association <italic>Saxifrago ferdinandi-coburgi-Seslerietum actarovii</italic> ass. nova has been established as a result of the phytosociological study. It is considered as an endemic vegetation unit from the calcareous subalpine terrains in the Central Balkan Peninsula high mountains (Southwestern Bulgaria, Former Yugoslav Republic of Macedonia, Northern Greece). The new syntaxon belongs to the alliance <italic>Edrajantho-Seslerion</italic> Horvat 1949. A comparison with related syntaxa from other calcareous mountains from Northern Greece and the Former Yugoslav Republic of Macedonia is discussed.</abstract>

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">The article provides the list of localities of <italic>Letharia vulpina</italic> in the eastern Julian Alps (northwestern Slovenia) that were recorded by the authors in 2010. Prior to this year the knowledge on the occurence of this lichenized fungus in Slovenia was insignificant (only one known locality, recorded already in the 19th century). With a phytosociological table we present the species composition and structure of natural subalpine larch stands (<italic>Rhodothamno-Laricetum deciduae</italic>) in which the species <italic>Letharia vulpina</italic> grows as an epiphyte on old and thick trees. It can also be expected in other Alpine regions in Slovenia where similar natural larch stands are preserved and the air is not over polluted.</abstract>

Distribution of <italic>Letharia Vulpina</italic> (Lichenized Ascomycetes) in the Subalpine Larch Stands (<italic>Rhodothamno-Laricetum</italic>) in the Eastern Julian Alps (Slovenia)

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml"><italic>Dysphania anthelmintica</italic> is recorded for the first time for Italy (Lazio region). Morphological and ecological characteristics of this plant and its invasive status, as compared with those of <italic>Dysphania ambrodioides</italic> and <italic>Chenopodium suffruticosum</italic>, are presented and discussed. Taxonomical notes are also provided.</abstract>

<italic>Dysphania Anthelmintica (Amaranthaceae)</italic>, New to the Non-Native Flora of Italy, and Taxonomic Considerations on the Related Species

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">The work deals with the floodplain forests of the Igneada region (NW Trace, Turkey). 69 relevés were sampled from wet to mesic sites according to the Braun-Blanquet approach and analyzed using different multivariate methods. The dataset was divided into five groups (associations), which demonstrate the diversity of forests in the region. In the wettest sites, forests dominated by <italic>Alnus glutinosa</italic> and <italic>Fraxinus angustifolia</italic> appear; on wet and nutrient rich sites along rivers there are forests dominated by <italic>Ulmus laevis</italic> and <italic>Fraxinus angustifolia</italic>; on wet and less nutrient rich sites <italic>Ulmus minor</italic> and <italic>Fraxinus angustifolia</italic> appear; on humid sites <italic>Fraxinus angustifolia</italic> and <italic>Carpinus betulus</italic> forests thrive and on mesic sites <italic>Carpinus betulus</italic> forests appear. The ecological conditions are estimated by bioindicator values and the gradient from wet and nutrient rich forests to mesic and nutrient poor forests is presented by numerical analysis. The species richness and geo-elemental structure for each community is evaluated. Finally, a syntaxonomical scheme is proposed and the following associations were determined <italic>Leucojo aestivi-Fraxinetum angustifoliae, Fraxino angustifoliae-Ulmetum laevis, Smilaco excelsae-Fraxinetum angustifoliae (Alno-Quercion roboris, Populetalia albae</italic>) and <italic>Geranio robertiani-Carpinetum betuli, Trachystemo orientalis-Carpinetum betuli (Castaneo-Carpinion betuli, Rhododendro pontici-Fagetalia orientalis</italic>) all within <italic>Querco-Fagetea</italic>.</abstract>

Diversity of Floodplain Forests in the Igneada Region (NW Thrace - Turkey)

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">A phytosociological survey of a woodland located in the central part of Umbria (Central Italy) was carried out using the Braun-Blanquet method: 80 relevés were classified through cluster analysis. Nine forest <italic>syntaxa</italic> were reported and three subassociations (<italic>Erico arboreae-Quercetum cerridis lathyretosum veneti, Aceri obtusati-Quercetum cerridis arbutetosum unedonis</italic> and <italic>Cyclamino hederifolii-Quercetum ilicis quercetosum cerridis</italic>) were typified. Topographic data (altitude, aspect, slope, morphology) and pedological data (soil pH, texture and depth) were collected and a synecological analysis of <italic>syntaxa</italic> was performed. In order to understand the relation between environmental factors and plant communities, a Canonical Correspondence Analysis was run. The results showed soil parameters (pH, texture and depth) and altitude as the main ecological factors explaining the distribution of plant communities in the study area. The combination of topographic factors (aspect, morphology and slope angle) influences, by contrast revealed the distribution of forest <italic>syntaxa</italic> within homogeneous geo-pedological and bioclimatic conditions.</abstract>
