The results of the analysis of literature on ecology and geographical distribution over zones and subzones of 23 Cryptophyta species of West Siberia fl ora are presented. Data on halobity, active water reaction and saprobity are given for each species. Nine species of limited occurrence in water bodies of West Siberia and Russia are indicated.

Morphological characters of the flowers and fruits of 31 genera of the family Boraginaceae of Altai Mountain Country are discussed. Separate keys for determination of genera on characters of the flowers and fruits are given.

The structure of generative sphere in three morphogenetic groups of Silybum marianum (L.) Gaerth. was studied. Th e complex of quantitative and qualitative morphological characters of holy thistle was analyzed with the “Radical index of contracting mapping system”. Significant taxonomic characters allowing to identify Silybum marianum specimens were revealed.

The revision of the Novopokrovsky’s collection (Herbarium of the Southern Federal University, Rostov-na-Donu (RV) is done. According new found data 12 species and 1 subspecies names of the genus Galatella Cass. (previously described by I.V. Novopokrovskiy) were typified. 5 holotypes are recognized, holo- and lectotypes are kept in RV, LE, AA.

Revealed a variety of class syntaxa Carici rupestris – Kobresietea bellardii Ohba 1974 for the East Sayan. To order Kobresio–Dryadetalia Ohba 1974 and alliance Dryadion oxyodontae Zhitlukhina et Onishchenko ex Chytry et al. 1993 attributed two associations ( Androsaco bungeanae – Flavocetrarietum cucullatae ass. nova hoc loco, Alectorio ochroleucae – Dryadetum oxyodontae ass. nova hoc loco) and two subassociations. To order Kobresietalia myosuroidis Mirkin et al. (1983) 1986 Ohba (1974) and alliance Kobresion myosuroidis Mirkin et al. 1983 em. Hilbig 2000 assigned three associations ( Dryado oxyodontae – Festucetum komarovii ass. nova hoc loco, Th alictro alpini – Betuletum humilis ass. nova hoc loco, Pulsatillo ambiguae – Caricetum pediformis ass. nova hoc loco), two subassociations and one community. A wide variety of class syntaxa Carici rupestris – Kobresietea bellardii due to a variety of climatic conditions, the East Sayan Mountains. Here are a humid-semihumid and semihumid-semiarid highlands.

Th e morphogenesis in vitro culture of two endemic species of the genus Fritillaria – F. dagana and F. sonnikovae was described. It is noted that the highest regeneration potential was developed from the bulbous scales. Th e development on two ways morphogenesis – direct organogenesis and indirect somatic embryogenesis was observed.

Transport and industrial effects on plants Potentilla fruticosa L. was studied. It has been established that decreasing the size of the leaf, the length of annual shoot, petiole, and reduced the content of fl avonoids of Potentilla fruticosa . It is shown that the content of phenolic compounds and fluctuating asymmetry value of Potentilla fruticosa terminal lobe a leaf corresponds to a high level of environmental pollution.
