Analysis of vertical and horizontal stand structure and stand disturbance history (minor releases revealed) is performed.
Based on the analyses results we found out special gap-dynamic form, which can be one of the main factors causing
complex mosaic stand structure of coniferous-broadleaved stand of the Russian Far East.
Species diversity of lichen biota of Tuva situated on the south of the Middle Siberia was studied. As result of the
generalization of the whole lichenologic information on this Republic the extent of species diversity currently
comprising 1325 species, 266 genera and 82 families has been determined.
Flora of lichens was studied in Kemerovo. 175 species from 32 familia and 64 genera are found. Two species are reported for the fi rst time in West Siberia.
Th e results of detailed SEM study of mericarp morphology and surface of 7 species of the sections Leptogalium, Trachygalium and Depauperata оf the genus Galium (Rubiaceae) are presented. Th ree types of the mericarp surface:
nipple-shaped, netted, hooked-netted have been singled out. It was concluded that characters of fruit morphology are able to use for elucidation of the relationships in the genus Galium.
In the fl ora of the Sakha Republic (Yakutia) there are 24 species of the genus Stellaria. Diagnostic characteristics of the species new to the fl ora of Yakutia and key for identifi cation of species are given.
Th e results of a taxonomic revision of the genus Salix, subgenus Chamaetia in the Asian Russia are presented. It has been established that the subgenus Chamaetia is represented in the fl ora of Asiatic Russia by 43 species belonging to
5 sections, 12 subsections, and 6 series. Th e characters that are of taxonomic signifi cance at the level of sections, subsections, series have been proposed. 5 subsections and 1 series have been described for the fi rst time.
Morphological characters of the erems, pubescence of the leaves and calyx show close relationship of endemic species from Baikal Siberia Mertensia serrulata to northamerican species M. ciliata.
The system and conspectus of the subgenus Pseudohackelia species of the genus Eritrichium (tribe Eritrichieae,
Boraginaceae) are presented. The conspectus includes 35 species. Information about nomenclature and typifi cation, data on ecology and geographical distribution, comments and fi gures, as well as the key for determination of all
taxons are given. New combination Hackelia sessilifructa is off ered in result of taxonomical revision. Variation Eritrichium fetisowii var. minor is described, holotypes of 4 species are established and shared out, lectotypes for
Eritrichium latifolium, E. fetisowii var. minor are chosen. Isotypes for E. relictum, E. pseudostrictum, E. turkestanicum are established and shared out. Areals of the most of species have been clarifi ed.
