The aim of the paper is the floristic analysis at the Krasnoyarsk forest-steppe pine cenoses. This problemrequires detailed research under the constant anthropogenic pressure. A flora inventory was carried out, vascular plantsspecies composition was determined. As a result, a summary of the flora was compiled, which includes 126 species from107 genera, 46 families, 6 classes, 5 divisions. Floristic analysis was carried out by the method of specific flora, taking intoaccount herbarium materials. The taxonomic, chorological, zonal, ecological, biomorphological flora structure featureswere determined based on the analysis of floristic data. The protected taxes have been identified. The peculiarities ofvegetation cover species composition are marked on the basis of the comprehensive flora analysis. The authors madethe conclusion that mesophytes of the light-coniferous and forest-steppe belt-zone groups with the Eurasian and EuroSiberian ranges predominate in the pine cenoses flora at the Krasnoyarsk forest-steppe. The most part of species havethe life forms hemicryptophytes and cryptophytes. Species to be protected have been discovered: Cypripedium calceolus,C. guttatum, C. macranthon, Neottianthe cucullata.

The purpose of the study was to identify the species composition of weed plants and its features on ruderal habitats on the territory of Vyborg city (Leningrad region, Vyborg district). Materials collected during the route survey of ruderal habitats on the territory of the settlement. Systemati-zation of monitoring data, floristic analysis of species composition, calculation of species occur-rence and assessment of its persistence were carried out. The specific structure is presented by 58 species, 48 genus, 18 families. Groups of 21 dominant and 15 concomitant in occurrence species are allocated. Brought species of weeds were revealed. The interrelation of species compositions of weed plants of segetal habitats of the region and ruderal habitats in the territory of the settlement is shown (17 species, identified on ruderal habitats of the city, are dominant in the fields of the region).

Fabaceae Lindl. or Leguminosae is one of the largest families of Angiosperms.  Due to adaptability in various climatic conditions, members of the family Fabaceae are worldwide in their distribution.  Globally, Fabaceae is represented by 770 genera and 19,500 taxa.  Bagalkot is one of the largest districts of northern Karnataka and falls under the Deccan Peninsular region of India.  The study area (Bagalkot District) is a rain shadow region and remains dry and hot throughout year.  During floristic analysis of the District the authors recorded 157 species of legumes, which is communicated here in relation to habitat, life forms, distribution, classification and their importance.

In terms of its plant richness, the Tien Shan occupies a special place among the mountain systems of Central Asia. According to many scientists, the Tien Shan is conditionally divided into three parts - western, central (inner) and northern. In the geographical nomenclature, onomastics and toponomics of modern sovereign Kazakhstan, the original name Tanirtau is used instead of the term Tien-Shan. Western Tanirtau is the most floristically rich mountain ecosystem in Kazakhstan, where the bioclimatic zones from deserts to glaciers are represented in all their diversity. The generic coefficient of the flora of Western Tanirtau is the highest in Kazakhstan and reaches 4.12, which indicates a high degree of autonomy and originality of the flora of Western Tanirtau.

Special report on dendroglaciological currently missing. The essence of the floristic analysis given in this paper is to identify the leading families of the dendroflora of Western Tanirtau. The species composition of tree and shrub plants collected and recorded in all natural, anthropogenic and urbanized ecosystems of Western Tanirtau were the objects of study. Research objectives: inventory of the species composition of the dendroflora of Western Tanirtau; compilation of the floral spectrum of the dendroflora; identification of the leading families of the region.

The paper presents the quantitative and qualitative characteristics of allergenic plants in the urban area of the Kragujevac city. The ecological characteristics of these plants were determined through ecological index and life forms. During the conducted floristic study, the presence of 78 allergenic plants was determined. Half of the recorded allergenic plant species are woody ornamental plant species. Floristic analysis shows that the allergenic plants are from the Pinophyta and Magnoliophyta divisions from 19 families, most commonly conifers and grasses.
