WIND EFFECT ON LIGHT AVAILABILITY UNDER CANOPY OF ACER SACCHARINUM L. AND A. PSEUDOPLATANUS L.
Different changes in light transmission under canopies of two maple species depending on biomechanical properties of leaves and branches are shown. Higher light transmission through Acer saccharinum crown under wind action (7 m/s) is due to long flexible branches and flexible petioles. Less intensive canopy light in A. pseudoplatanus stand under the same wind velocity and crown density can be explained by rigidity of leaves and branches. Brighter light conditions under silver maple allow understory to grow in the silver maple stand.

LICHENS OF THE M.M. GRYSHKO NATIONAL BOTANICAL GARDEN (KYIV, UKRAINE)
Results of a floristic survey of lichens occurring in M.M. Gryshko National Botanical Garden are presented. 51 lichen species and one lichenicolous fungus, Athelia arachnoidea, are listed. Rinodina septentrionalisis reported as a new record for Ukraine. Despite high diversity of phorophytes in the Botanical Garden, its lichen species diversity is low. Most of the lichen species in the Botanical Garden are tolerant to urbanization and frequent in the built-up area of Kyiv city. Only a few species sensitive to urbanization were recorded. The lichen species diversity patterns on natural and introduced phorophytes are very similar, which is probably be caused by environmental pollution in Kyiv.
TERRESTRIAL ALGAE OF ZMIINYJ ISLAND (BLACK SEA, UKRAINE): GENERAL CHARACTERISTIC AND PECULIARITIES OF SPECIES COMPOSITION
In 2008–2009 we studied biological crusts, moss patches and soil collected from Zmiinyj Island (Black Sea, Ukraine). In these samples we identified in total 92 eukaryotic and prokaryotic algae. The majority of those were green algae (Chlorophyta 55; Streptophyta 5 species), but also twelve cyanoprokaryotes, eight xanthophytes, eight diatoms, and one eustigmatophyte were found. Mіschococcus sphaerocephalus Vischer and Trichosarcina polymorpha K.H. Nichols et Bold were recorded for the first in Ukraine. In addition, some rare taxa, Chlorokybus atmophyticus Geitler, Myrmecia israeliensis (Chantan. et Bold) Friedl et al., Chondrocystis dermochroa (Nдg.) Komбrek et Anagnostidis, were observed. The three different biotops were not only different in their species composition, but also in their species abundance. In soil samples the highest species diversity was registered, in contrast to biological crusts on cliffs where only 25 species were found. In moss patches several species were observed which normally prefer aquatic environments.
VITALITY STRUCTURE OF COENOTIC POPULATIONS OF NYMPHOIDES PELTATA (S.G. GMEL.) KUNTZE (MENYANTHACEAE) IN DESNIANSKO-STAROGUTSKYI NATIONAL NATURE PARK
A morphometric analysis of 34 parameters for N. peltata ramets from five coenopopulations growing under different ecological conditions was conducted. A group of morphoparameters determining vitality was established. Based on morphometry data, coenopopulation vitality was analysed. Among the surveyed coenopopulations, two were found prosperous, one balanced, and two depressive. The ecological coenotic optimum for N. peltata in the studied region was defined. A non-destructive method for investigation of the coenopopulation vitality for N. peltata was developed.

ON SOME TAXA OF VASCULAR PLANTS REDISCOVERED IN THE CRIMEA
Five taxa of vascular plants (Nigella elata Boiss., Fumaria petteri Rchb. ssp. thuretii (Boiss.) Pugsley, Avena eriantha Durieu, Lolium remotum Schrank, Hesperis matronalis L.) have long been thought doubtful for the Crimean flora. Based on new findings in nature over the period of 1996—2010 together with results of revision of herbarium specimens, it has been proved that these taxa do grow in the territory of the Crimean Peninsula at present. Some aspects of their morphology, ecology and chorology are discussed.

COMPARATIVE MORPHOLOGY OF FLOWER OF THE SPECIES OF ACONITUM L. (SECTION ACONITUM L.) IN THE FLORA OF UKRAINE
The specific value of about 30 characters of the main flower elements of ten species of the genus Aconitum L. (section Aconitum L.) in the flora of Ukraine is justified on the basis of comparative-morphological investigation. We paid special attention to form and size of a helmet and its beak, spurs of petal-nectary, special features of stamens, character of filament stamens and pistil hairiness. Asymmetrical lateral sepals and dimorphic perianth basal sepals in some species of the genus were noted.
SYSTEM OF THE CYPERACEAE JUSS. FAMILY IN UKRAINIAN FLORA
Modern systems of the Cyperaceae family based on molecular phylogenetic research are analysed. Using the most recent information on systematization and generalization of taxonomic diversity, a compiled system of the Cyperaceae family of Ukrainian flora is presented. It includes one subfamily, 8 tribes, 19 genera and 153 species. For each taxon nomenclature citation is provided.
VIOLA ODORATA L. (VIOLACEAE) AS A REMNANT OF FORMER CULTIVATION IN THE BIALOWIEZA FOREST REGION
Bialowieza Forest region. V. odorata is a species of uncertain status in Poland. According to the literature, the species is generally rare in Bialowieza Forest, NE Poland. Recent observations show that the species is much more common in the Bialowieza Forest region and should be treated here as a kenophyte/hemiagriophyte. Most localities are in parks, cemeteries, at roadsides, wasteland, along fences and under the canopy of trees close to human settlements. Four different colour forms were found: the most common were violet, purple, white and lilac.
VARIABILITY OF THE ALIEN SPECIES ANTOXANTHUM ARISTATUM BOISS. (POACEAE) IN THE WIELKOPOLSKA LOWLAND (WESTERN POLAND)
Morphological variability of Anthoxanthum aristatum Boiss. populations was examined. Multivariate statistical analysis of 24 morphological characters of the panicle obtained from six sample populations (138 specimens) collected in different habitats was carried out. The analysis of variance ANOVA indicated significant morphological variations among samples. The principal component analysis (PCA) revealed three groups of samples. These groups are not completely separated from each other and sometimes overlap. Canonical discriminate analysis (CDA) proved useful for variety discrimination of characters such as: panicle length and length of internodes, spikelets on the second and the middle branching from the panicle top and upper glume. Weak correlations were detected between morphological differentiation of A. aristatum populations and the habitat type they occupied.
NEW NOMENCLATURAL COMBINATIONS IN BLITUM L. AND KALI MILL. (CHENOPODIACEAE): TAXA OCCURRING IN EASTERN EUROPE
Five new combinations (four at the section level and one for a hybrid) are validated in the genus Blitum L. and one new combination at the subspecies level is made in the genus Kali Mill. (Chenopodiaceae). Segregation of these genera from Chenopodium L. and Salsola L., respectively, is briefly discussed.

Laundon, Muelleriella pygmaea (Kцrb.) D. Hawksw., Megalaria pulverea (Borrer) Hafellner & E. Schreiner, Oxneria huculica S.Y. Kondr., Pachyphiale fagicola (Hepp) Zwackh, Phoma pisutii S.Y. Kondr. et al., and Psilolechia lucida (Ach.) M. Choisy, are also provided.
The ranges of sexual types and life strategies of bryophytes on the rock dump of Jaziv sulphur deposit of Novoyavoriv mining chemical enterprise "Sirka" have been determined. It was established that on initial stages of bryophyte succession acrocarpous dioecious colonist-species prevail due to alternation of vegetative and generative reproduction, decrease of ontogeny duration and age of first reproduction. The sex dimorphism, different rate of plant maturation, of productivity and different capacity for reproduction are the main factors causing deviations in sex ratio and promoting cross-fertilization in dominant dioecious species, thus supporting the high level of genetic variability and stability of moss colonists under conditions of devastated territories.
NEW INFORMATION ON DISTRIBUTION OF ADVENTIVE MOSS СAMPYLOPUS INTROFLEXUS (HEDW.) BRID. (LEUCOBRYACEAE) IN UKRAINE
New data on the occurrence of the adventive moss, the neophytic Сampylopus introflexus (Hedw.) Brid., in Ukraine is recorded. Two new habitats of the species were discovered in June 2009 and September 2011 during surveys on the peats of Lviv Region. Characteristics of the two new habitats of the species are given. The ecological phytocoenotic conditions, dynamic tendencies and limiting factors of С. introflexus distribution in Ukraine are discussed.

SYNATHROPIZATION OF XEROTHERMIC GRASSLANDS IN THE DZIALY GRABOWIECKIE (LUBLIN UPLAND, SE POLAND)
The Dzialy Grabowieckie region is located in the Lublin Upland (SE Poland). The occurrence of xerothermic grasslands is typical for this region. Twenty-two sites with xerothermic grasslands were investigated in 2005-2009. In the course of the study, we registered both synathropic vascular plant species, which were permanently connected with grasslands, and those aliens that present a potential threat for native species or ecosystems. The available published data was used to compare the past and present occurrence of synathropic species in xerothermic grasslands. The number of synathropic species decreased together with the cessation of use. Some archeophytes (e.g. Onobrychis viciifolia, Pastinaca sativa, Cichorium intybus) are at present permanently connected with xerothermic grasslands; however, kenophytes, such as Robinia pseudoacacia, Solidago gigantea and S. canadensis, pose a potential threat for xerothermic plant communities.
BRYOPHYTES OF THE EXPERIMENTAL AND TEACHING GARDEN OF THE FACULTY OF BIOLOGY AND ENVIRONMENTAL PROTECTION, UNIVERSITY OF LODZ (POLAND)
The aim of the study was to determine the species composition, taxonomic and ecological diversity of bryophytes of the examined site and to determine their prevalence in the area. During the research, there were showed the presence of 42 species of bryophytes (41 mosses and one liverworts) belonging to 15 families. The shown species represent 29 % of all the species identified in the city of Lodz and surrounding area. In this group there were 7 species not reported so far in this area. The research showed five types of habitats covered by bryophytes, they are: epigeic, epilithic, epiphytic, epixylic, and aquatic. Most species were found in the examined area, in epigeic habitats — 34 species, least were found in aquatic habitat — only one species. A large number of identified species confirms that urban parks are characterized by a large diversity of species of bryophytes. The large number of species unlisted in this area so far confirms the validity of the green areas as the significant mainstays of briological diversity of a relatively floristically poor urban areas.
PALEOBOTANICAL CHARACTERISTICS OF UNIQUE FINDINGS FROM ARCHAEOLOGICAL EXCAVATIONS (UKRAINE)
For the first time summarizes the results of palynological analysis of six unique individual samples collected during archaeological excavations in the territory of Ukraine. Palaeopalynological and paleoethnobotanical characteristics are represented in this article. For each of the samples general composition of the fossil palynoflora was determined and the results of generic (42 taxa) and species (47 taxa) identification of pollen grains and spores were summarized. We have shown by example the perspective of palaeopalynological characteristics for the reconstruction of pictures of natural and human-induced changes in the structure of vegetation of the last, received for the single, but clearly archaeologically dated sample.
GENUS ASPLENIUM L. (ASPLENIACEAE) IN THE NATURAL FLORA OF UKRAINE
According to the results of taxonomic revision was established that the genus Asplenium L. in the natural flora of Ukraine is represented by 14 species, but presence of A. fontanum (L.) Bernh. needs additional confirmation. Idea about modern distribution of A. × heufleri Reichardt and A. cuneifolium Viv. in territory of the country has been changed. Also the data about distribution of the other species of this genus, especially A. × alternifolium Wulfen ex Jacq., A. obovatum Viv. subsp. lanceolatum (Fiori) P. Silva and A. septentrionale (L.) Hoffm. were supplemented. The necessity of inclusion of into the floristic list of Ukraine has been proved.

TUBULIN CYTOSKELETON IN CELLS OF ROOT APICES IN ALISMA PLANTAGO-AQUATICA L. (ALISMATACEAE) AND SIUM LATIFOLIUM L. (APIACEAE), AERIAL-AQUATIC PLANTS
The article highlights the organization of tubulin cytoskeleton (endoplasmic and cortical microtubules) in cells of different root zones in aerial-aquatic plants, Alisma plantago-aquatica L. and Sium latifolium L.. The topography of microtubules in cells adjacent to aerenchyma cavities and those not adjacent is compared. The interspecies difference in the organization of tubulin cytoskeleton in the root cells adjacent to cavities is revealed. It is suggested that microtubules play a signal role in the process of aerenchyma formation.

The endemic petrophyte-steppe shrub formation of Chamaecytіceta granitici is described. Description of selected on dominant basis associations, forming ecological-coenotic row according to gradients of humidity, density, and disturbance of substrate, is provided. The described associations are dated exceptionally to outcrops of limestone rock of Upper Sarmat-Pleistocene age.
RESERVES OF LITTER ON FLOODED MEADOWS OF THE LEFT-BANK FOREST-STEPPE OF UKRAINE
It was found that reserves of plant litter in the flooded meadows of the region vary within 24,8—297,3 g/m2. Weather conditions, particularly temperature and rainfall, affect its accumulation. The amount of litter is conditionally divided into three groups. Majority of the floodplain sites belong to the second group of grass stands (51,0 — 89,9 g/m2). The dry matter content in litter gives some idea of the yield on certain areas. It is shown that lower economic pressure, including various degrees of protection, leads to increase in the litter reserves.
RARE ELEMENTS OF THE SEGETAL FLORA PRESERVED IN ABANDONED VILLAGES IN THE KAMPINOS NATIONAL PARK (CENTRAL POLAND)
Floristic studies were conducted in 15 abandonded villages in the Kampinos National Park during the years 1992–1995 and 2004–2007. This paper presents interesting segetal species found in these areas. Thirty four rare segetal taxa were found, including 25 threatened and vulnerable species. In the field marginhabitats 110 species were found. Apophytes constitutied the major group of species (about 47 %) and archaeophytes were less numerous (about 38 %). The aims of the present study were to determine whether the surveyed sites can function as a potential source of diaspores of rare segetal species and to establish if abandoned villages are important for biodiverisity preservation.
MORPHOLOGY OF POLLEN GRAINS OF REPRESENTATIVES OF BIDENS L. (ASTERACEAE) IN THE VALLEY OF THE MIDDLE DNIPRO

THE ABORIGINAL FRACTION OF THE URBAN FLORA OF CHERNIHIV
The species composition of aboriginal fraction of the Chernihiv urban flora is established. It contains 765 species (73 % of the total number of the urban flora) belonging to 347 (74 %) genera and 97 (84 %) families. An analysis of its structure is given. It is demonstrated that the aboriginal fraction and the urban flora of Chernihiv retain zonal properties. The apophytes are represented by 240 species which is 23 % of total number of the urban flora, 31 % of the aboriginal fraction, and 46 % of the synanthropic fraction. The structure of the apophytes corresponds with the aboriginal fraction and urban flora of Chernihiv. Retainment of zonal properties of the urban flora in Chernihiv in future depends on apophytization since the apophytes are most resistant to anthropogenic influence.

MYRINIA PULVINATA (WAHLENB.) SCHIMP. (AMBLYSTEGIACEAE), A NEW SPECIES AND GENUS FOR THE BRYOPHYTE FLORA OF UKRAINE
Myrinia pulvinata (Wahlenb.) Schimp. (Amblystegiaceae, Bryophyta) is reported for the first time for Ukraine. It was found on a trunk of Tilia cordata in the green plantation of Kharkiv city (SE Ukraine, 49°57'39”N - 36°19'19”E). Peculiarities of ecology, distribution and taxonomic position of the species are discussed.
LECCINUM SPECIES (BOLETALES, BASIDIOMYCOTA), NEW AND RARE IN UKRAINE
As a result of critical study, 15 species of the Leccinum genus are reported for Ukraine. Leccinum aurantiacum, L. pseudoscabrum, L. scabrum, and L. versipelle are found to be common species. Leccinum crocipodium, L. duriusculum, L. holopus, and L. vulpinum have each up to 15 records. Leccinum albostipitatum, L. melaneum, L. palustre, L. piceinum, L. schistophilum, and L. variicolor are very rare species (1—3 records in the country). Leccinum albostipitatum, L. melaneum, L. palustre, L. piceinum, and L. schistophilum are new for Ukraine species. Based on the literature data only, distribution of L. rufum is impossible to assess.
NEW FOR UKRAINE DISCOMYCETES FROM THE SHATSK NATIONAL NATURE PARK
During a mycological expedition to the Shatsk NNP in summer 2011, two new for Ukraine discomycetes were recorded. Brief descriptions and drawings of Neottiella vivida (Nyl.) Dennis and Otidea mirabilis Bolognini & Jamoni are given.
ANATOMICAL FEATURES OF LEAVES OF SPECIES OF CAMPANULA L., AQUILEGIA L. INTRODUCED IN STEPPES OF UKRAINE
Peculiarities of the leaf anatomical structure of Campanula L. and Aquilegia L. species introduced in the steppe zone of Ukraine were studied. It was found that adaptation of mesophyte species of herbaceous perennials consists in enlargement of layers of accumulated parenchyma, thickness of mesophyll, epidermis, mechanical properties of leaf petiole, appearance of stomata on the upper surface of a leaf, smaller quantity of stomata on the bottom surface and their simultaneous increase in size.
POLYMORPHISM OF NUCLEUS-NUCLEOLUS PARAMETERS OF PICEA ABIES (L.) KARST. (PINACEAE) SEED PROGENY IN THE NATURAL POPULATIONS AND INTRODUCTION PLANTATION
Cytogenetic quantitative polymorphism was studied in the Picea abies (L.) Karst. seedlings. Seeds were collected from trees in two natural populations of Ukrainian Polesie and introduction plantation in Donbass and grown in the laboratory. It was established that interphase nuclei in offsprings of trees from the plantation and the population in areas with high radioactivity level are smaller than in population with low anthropogenic influence. The number of nucleoli and their area, and nucleus-nucleolus ratio was the lowest in the tree progeny from the introduction plantation. Environmental conditions (including radioactive pollution) affect the seed progeny of P. abies which is reflected in its cytogenetic characteristics.
EFFECT OF SHORT-TERM TEMPERATURE STRESSES ON LEVEL OF ABSCISIC ACID IN PLANTS WITH DIFFERENT TYPES OF ECOLOGICAL STRATEGY
We analyzed the changes in level of free and conjugated forms of abscisic acid (ABA) in 7-days seedlings of plants with different types of ecological strategy after short-term high and low temperature stresses. It was revealed that in control conditions level of conjugated form of ABA in all analyzed species was higher compared with free form of phytohormon. Explerents A. caudatus and B. campestris characterized by highest level of free and conjugated forms of ABA in control conditions. Level of phytohormon in patient R. patientia x R. tianshanicus was lower compared with violent F. pratensis and explerents A. caudatus and B. campestris. The obtained data allow to conclude that changes in level of conjugated and free forms of ABA of investigated plants after short-term temperature stresses correlate with the type of their ecological strategy. ABA contents may be used as possible biomarker of plants thermotolerance and their ecological strategy type.
