The article considered to the systematic (taxonomic) structure fern’s fl ora (pteridoflora) of Baikalian Siberia in comparison with neighboring regions (the Altai and Krasnoyarsk regions, Amur oblast and Mongolia). Are used the methods of comparative floristic. Mathematically calculated similarity compared pteridofl oras. Revealed regional features of fl orogenesis.

The features of morphology Padus avium Mill. four population groups, localized on the territory of Perm region (380 plants), Novosibirsk region (314 plants), Shebalinsky and Chemalsky regions of the Altai Republic (278 and 298 plants) and 14 characters of the generative and vegetative organs. Determined the level of variability of plants on the studied characteristics.

Data on type specimens for three infraspecific taxa of the genus Dianthus L., described from Eastern Siberia, are given. Taxa are hold in M.G. Popov Herbarium of the Central Siberian Botanical Garden, SB RAS (NSK). Lectotypes, isotypes and paratypes are identified. A new nomenclatural combination D. versicolor subsp. ninelli (Peschkova) Baikov et N. Vlassova, comb. et stat. nov. is proposed.

The key for determination and synopsis of the four species from the section Geranium of the genus Geranium , growing in forest, forest-steppe and subalpine mountain belts of the Urals, Siberia and the Altai Mountain Country are presented. As a result of a comparative study of morphological features diagnostic signs of leaf, calyx and corolla of a flower, the pubescence of the pedicels are shown. A new species - G. igoschinae Troschkina from the territory of the Urals related to G. pseudosibiricum is described.

Two new species of the genus Craniospermum Lehm. ( Boraginaceae Juss.). from Mongolia are described. Th e morphological and ecologo-coenotical peculiarities of the new species C . desertorum Ovczinnikova et A. Korolyuk from the sect. Leucolachnos Ovczinnikova and its distinctions from C. canescens DC., and new species C . pseudotuvinicum Ovczinnikova et A. Korolyuk from the sect. Diploloma (Schrenk) Popov and its distinctions from C. tuvinicum Ovczinnikova are considered. The new localities of C. mongolicum I.M. Johnst. and C. echioides (Schrenk) Bunge are indicated and the description of plant communities with their participation is given.

The article contains information about the type materials for 19 taxa of the family Asteraceae , 5 taxa of the family Euphorbiaceae and 3 taxa of the family Scrophulariaceae kept in M.G. Popov Herbarium of the Central Siberian Botanical Garden SB RAS (NSK). The type category is indicated, text of the original label and text of protologue are cited for each specimen. 108 type specimens were found in collections, including 18 holotypes, 15 isotypes and 71 paratypes, 4 authentic specimens.

The results of study the lichens tundrae were generalized within the boundaries of the mountain systems of the Northern Asia. Their species composition and fundamental regulations of spatialis distribution were revealed. Arcto-alpine species of the widespread are making basis of the coenoflorae cum lichens, tum plantae vasculares. 11 typi lichens synusiae determinativus structura and variantia of the associations was revealed. Schema refl ecting, structuralis and typologicus diversity of lichens tundrae are compiled. Short description of the fundamental associations was led.

The results of study of phenological rhythms, reproductive biology and winter hardiness of Alstroemeria cultivars indoors and outdoors in the forest-steppe zone of West Siberia are presented. The optimum cover material for winter protection has been chosen. Fertility and viability of the pollen grains were studied. The medium containing 28 % of sucrose and 0.001 % of boric acid turned out to be optimal for germination of alstroemeria pollen of the cultivar Regina . The recommendations for use of alstroemeria in landscape design in the forest-steppe zone of West Siberia are given.

Radiosensibility of seeds of 21 plant species belonging to 10 families and growing in Central Yakutia was studied. Among them, 18 species were examined for the first time. The taxonomical differentiation by families in respect to resistance of seeds to gamma irradiation was shown. The variability in radiosensibility was stated to be dependant on temperature-humidity conditions during vegatation and seed ripening.
