Morphogenesis of the individuals, structural-morphological polyvariation of the Nepeta podostachys Benth. shoot systems and the ontogenetic structure of coenopopulations in different ecological-phytocoenotic conditions of Tajikistan were studied. Structural-functional areas of the monocarpic shoots and their polyvariation were described. It was established that studied three coenopopulation were normal but old individuals or may be absent. Th eir ontogenetic spectra had centric and left-hand types. The resulting spectra reflect the pace of development of individuals and polyvariation of ontogeny.
Sexual structure of 21 coenopopulations in gynodioecious Schizonepeta multifi da was studied in the forest-steppe in Kuznetsk Highland. Three types of coenopopulations - unbiased sex ratio (40.9-58.0 % hermaphrodite individuals), female (from 59.4 up to 68.2 %) or hermaphrodite (from 58.5 up to 70.2 %) individuals dominate were singled out by a sexual spectrum.
The system and conspectus of the genus Puccinellia Parl. ( Poaceae ) species is presented. The conspectus includes 44 species from the 10 sections and 8 subsections. Information about nomenclature and typification, data on ecology and geographical distribution, comments and figures of new diagnostic features: form of ligula and structure of panicle, as well as the key for determination of all taxons are given. Section and 2 subsections are described, 3 new combinations in rank of section and subsection is offered in result of taxonomical revision. A new species for the flora of Russia and Eurasia P. andersonii is discovered, P. paupercula are reestablished, P. fi lifolia is striked off structure of fl ora. Asian species P. jacutica , P. neglecta are brought for the flora of North America for the first time. Areals of the most of species are have been clarifi ed.
Studied geographical regularities of changes of floristic composition of forest phytocenoses of the West-Siberian Plain along the latitudinal gradient from 55 to 68° N. Identified groups of species of higher vascular plants, which, on the basis of its occurrence is diagnosed latitudinal the boundaries of the zones and subzones of the spread of forest vegetation.
The results of the restoration (within 4 years) of the populations of Hedysarum theinum Krasnob. - endemic to the Altai, growing on the Mountain Red in the Altai Republic. Recommended as the best method for restoration and reintroduction of this species of use sowing of the untreated seeds in the soil at any time of the vegetative season. Th e effectiveness of restoration was less than 10 %.
The results of algal flora study in different-type water bodies in Saline Tuzlukkol Hole were presented. 175 species, varieties and forms from 5 divisions (Cyanoprokaryota - 10, Bacillariophyta - 126, Chlorophyta - 31, Euglenophyta - 6, Cryptophyta - 2) were revealed. The ecological and geographical analysis of the algal flora was performed. New taxa of algal flora for Orenburg region were found out.

The descriptions and localities in Baikal Siberia of two lichen species Collema pulcellum Ach. var. pulcellum and C. ryssoleum (Tuck.) A. Schneid. are provided. A new form C. pulcellum var. pulcellum f. isidiosum Makryi, f. nov. is described. It has been established that literary data about distribution of C. nigrescens (Huds.) DC. and C. subni grescens Degel. in south part of East Siberia and Russian Far East are erroneous. In fact, being widespread species in these regions is C. pulcellum var. pulcellum , while C. nigrescens and C. subnigrescens das not occur at all. Expressed the view that the volume of species C. pulcellum s. l. sensu G. Degelius is too large and poorly correlated with the volumes of other Collema species of Nigrescens -group. Taking into account the signifi cant differences in the morphological and anatomical structure of thalli, shape and size of spores, and character of areas, it would be correct to consider all three varieties (var. pulcellum , var. subnigrescens (Müll. Arg.) Degel., and var. leucopeplum (Tuck.) Degel.) as separate species, as they have been described.
Alluvial forests of the upper Ob River were studied in central part of the forest-steppe zone of Western Siberia, Kamensky district of the Altai Territory, 53°40′50″ N, 81°57′30″E. In these forests, 49 epiphytic lichens were revealed, including 26 species in willow ( Salix alba ) forest and 47 species in poplar ( Populus nigra , P. alba ) ones. 30 species on willow and 45 ones on poplars were noted.
Characteristics of moss species composition and occurrence in zonal dark coniferous forests West Siberian middle and south taiga subzones are given. 64 moss species are listed in sum.
