The original identification key and the checklistof the family Limoniaceae Lincz. in the flora of Ukraine are provided. Nomenclatural citations, basionym, main synonyms, and data on distribution in Ukraine and in the world are presented in the checklist for each species. Taxonomic opinions of the author are given in notes to each taxon, the most reliable diagnostic feature are specified as well. New nomenclatural combinations are proposed. In particular, new combinations at the subspecies rank are validated for 3 taxa of the Limonium tomentellum aggr.: L. tomentellum (Boiss.) O.Kuntze subsp. alutaceum (Steven) Moysiyenko comb. nova, L. tomentellum (Boiss.) O.Kuntze subsp. donetzicum (Klokov) Moysiyenko comb. nova., L. tomentellum (Boiss.)

Mill., L. suffruticosum (L.) O.Kuntze, L. tomentellum (Boiss.) O.Kuntze subsp. alutaceum (Steven) Moysiyenko, L. tomentellum (Boiss.) O.Kuntze subsp. donetzicum (Klokov) Moysiyenko, L. tomentellum (Boiss.)

Distribution of narrow endemics in Crimean landscapes is elucidated with revealing of some plant geographical features.
Current status of studying mire vegetation in Ukraine is elucidated. It is proved that these investigations is connected with development of general mire science together with requests of the national economics. The results of investigations and achievements of Ukrainian school of mire science in geobotanical, stratigraphic directions and plant conservation together with challenges are reviewed.
The results of critical taxonomic study of the genus Vicia L. in the flora of Ukraine are presented. The analysis of species of the genus in Ukraine (38 species) is given according to the modified system, which includes 4 subgenera, 12 sections and 11 subsections.

The data on current composition of phytoplankton dominant complex of Eastern Sivash (Ukraine) together with the analysis of its changes from the beginning of the XXth century up to the recent time are presented. Changes in phytoplankton community composition from euhalobic-polyhalobic, euhalobic and mesohalobic are shown during the XXth century up to oligo-mesohalobic at the beginning of the XXI century. Such tendency is associated with the modern data about desalination process of Eastern Sivash at the recent time.
Participation of widespread pleurocarpes moss from the order Hypnales in bryocommunities is analized. It is found out that species studied prevail in 64,1 % of epiphytic and epixylous communities being also diagnostic species of associations, with insignificant coenotic participation in 24,4 % communities .
The classes of constancy of spiecies studied are those: for Hypnum pallescens Hedw. P. Beauv., – III, Platygyrium repens (Brid.) Shimp., Pylaisia polyanthа (Hedw.) Schimp Amblystegium serpens (Hedw.) Schimp – II, Leskea polycarpa Hedw.– I. A classification of briocommunities following Braun-Blanquet method with appropriate characteristics is reported. The association Ptilidio pulcherimi-Hypnetum pallentis Barkm. ex Wilm. 1962 and its phytocenotic description is given in Ukraine for the first time.
It was investigated the species composition and especially of distribution the seaweeds in connection with ecological conditions of different areas of Odessa coastal. Was show that lowering of salinity and increasing level of pollution lead to simplification the structure of bottom phytocenosis and reduce their floristic diversity.
The effect of heavy metals Zn2+, Pb2+ and Ni2+ on free proline content and superoxide dismutase activity in mosses Hylocomium splendens, Pleurozium schreberi and Rhytidiadelphus squarrosus. The effect of Cu2+ and Cr6+, low and high temperatures and osmotic stress in relation to proline content and catalase activity were estimated in liverwort Marсhantia polymorpha. It was found that proline accumulation was more pronounced under high temperatures and osmotic stress than in the presence of heavy metals. It is concluded that in tolerant species stress conditions may enhance protective processes such as accumulation of free proline and increase in the activities of detoxifying enzymes superoxide dismutase and catalase.
Typical morphological changes of epiphytic moss transplantats under the impact of environmental pollution in the city of Makeyevka (Donetsk region) are revealed. It is found that the degree of morphological characteristics of Orthotrichum pumilum Sw. (=Ortotrichum fallax Bruch.) and Leptodictium riparium (Hedw.) Warnst. positively correlates with the level of air pollution. These species can serve as the informative indicators of air quality in an industrial region. Relatively highly tolerance of Leskea polycarpa Hedw. to intensive air pollution is confirmed. The degree of anthropogenic pressure in three zones of Makeyevka (Donetsk region) is determined.
The effect of exogenous hydrogen peroxide on lipid peroxidation and activity of antioxidative enzymes in shoots of the aquatic moss Fontinalis antipyretica is studied. It was shown that proper concentrations of H2O2 does not lead to accumulation of lipoperoxidation products, but modulate evidently the activity of antioxidant enzymes. Increasing of catalase and peroxidase activity under the influence of 1 and 10 mM H2O2 is revealed. Decreasing of glutathione reductase activity under the influence of Н2О2 is recognized with change of redox-status in the plant cells as possible cause of it.
On the base of individual and common characters, general ecological and biological features of small populations of rare plant species in the high mountain zone of the Ukrainian Carpathians are stated. An indicator characters for evaluating their viability are determined. The most important among them the genetic variability, effective and general number, habitat area, number dynamic, especially for flowering individuals; efficiency of seed and vegetative reproduction; intrapopulation variability; vitality, variability and duration of individual ontogeny; mutual effect of neighbouring species . Some aspects of ecological structure of small populations of different life forms species at nature conditions and under the anthropogenic factors are elucidated.
