Abstract >>
Not differences were detected in hermaphroditic and female individuals D. nutans L. in characteristics of seed productivity: the number of seeds per generative shoot is 144.8 ± 9.11 PCs. and 141.0 ± 12.63 PCs.; coeffi cient of seed productivity of 41.1 and 40.9 %; weight of 1000 seeds - 0.31 ± 0.006 g and 0.32 ± 0.005 g, respectively, for hermaphrodites and females. In the offspring of hermaphrodites in this population dominated by hermaphrodite individuals - 82.4 %, female - 8.4 %, transitive individuals - 9.2 %. In the offspring of females dominated by female individuals - 66.3 % , hermaphrodites - 17.5 %, transitive individuals - 16.2 %. The high reliability of the difference between hermaphrodites and females by sex distribution in the first generation offspring was established (Chi-square criterion 93.14, p < 0.001) . The ratio of individuals in the sexual structure of the initial population is 69.8 % hermaphrodite and 30.2 % female phenotypes. The phenotype frequency analysis of the fi rst generation offspring from hermaphrodite and female individuals at all possible crossings showed that the frequency of the female phenotype is 0.259.

Abstract >>
The spatial structure of the leaf blade mesophyll of evergreen woody plant Nageia nagi (Thunb.) Kuntze ( Podocar paceae ) is considered. N. nagi leaves are dense, wide, with numerous parallel longitudinal veins. The cell organization of chlorenchyma was studied on transverse and longitudinal sections of leaf blades. The assimilation parenchyma is multi-layered, differentiated and consists of cells of a simple form. It is represented by palisade and spongy tissues, between which there are large elongated median cells across the leaf, or cells of an intermediate type, interacting with each other by small end surfaces. The palisade cells are cylindrical or cone-shaped forms, the cells of the spongy parenchyma differ mainly in size along the leaf, among them are narrow, thickened and close to globular. Hydraulic compartmentalization in the leaves of the N. nagi can be caused by the presence of three types of mesophyll cells. The considerable volume of chlorenchyma in the leaves is occupied with median cells, mainly through which water is transported from conducting bundles to the spongy layer and stomata located on the lower surface. The part of these cells can perform water reserving function. The spatial organisation of mesophyll of multinervate leaves N. nagi largely resembles of that in uninerved leaves of conifers with simple-shaped cells.

Abstract >>
Basing on materials from the herbarium FRU (Institute of Biology of Kyrgyz National Academy of Sciences), the genus Psathyrostachys Nevski ( Poaceae ) was analyzed. Kyrgyz flora consist of four species of this genus: P . hyalantha (Rupr.) Tzvelev, P . juncea (Fisch.) Nevski, P . kronenburgii (Hack.) Nevski, P . lanuginosa (Trin.) Nevski. Synopsis of the genus is presented, with brief nomenclature citations and the key for identifi cation. The review is accompanied by illustrations - photos of spikelets and distribution maps of all species, with footnotes given when necessary. P . hy alantha was discovered in the territory of the Kyrgyz Republic for the fi rst time. The distribution of species in the territory of Kyrgyzstan is given according to phyto-geographical dividing, where inner areas are: Northern Kyrgyzstan, Issyk-Kul Lake basin, Central Tien Shan, Western Tien Shan, Cis-Ferganian regions, Inner Tien Shan, Alai Valley.

Abstract >>
The peculiarities of the seasonal development of 35 perennial species (one dwarf semishrub and herbaceous polycarpics) of Western Transbaikalia were studied at the introduction in Novosibirsk. 13 groups were identifi ed according to the main rhythmological features: the time of spring regrowth, the beginning of flowering and the duration of the growing season. Most of the species belong to the most common phenorhythmotype of perennial in the forest-steppe of West Siberia such as long vegetating, with early or medium time of regrowth, early summer or summer flowering and winter dormant period. In the collection of ornamental plants of natural flora Transbaikalian perennials later recover in spring and later bloom. Of these, 15 species the most sustainable and durable are promising for culture.

Abstract >>
Based on the analysis of literary sources, the main types of trichomes in the large tropical genus Begonia are identifi ed. These are monoserial and multiserial hairs of different structure, peltate scales, as well as a variety of glandular head hairs and peltate glands. As a result of generalization of published materials it has been established that the most common variants of non-glandular hairs in the genus Begonia are multicellular multiserial non-branching tri chomes and emergences. Branching (tree-like) hairs are less common and their presence is a diagnostic trait of a spe cies level for some Brazilian and East Asian begonias. As a result of aggregation of single trichomes more complex structures are formed. These are bunchy trichomes, clusters of multiserial trichomes and comb-shaped (or collar-shaped) scale-like structures. The article discusses the taxonomic and adaptive significance of pubescence traits.

Abstract >>
Bibliography of botanical literature of Tyva given in the article encompasses the period from the end of the 19th to the beginning of the 21st century (from 1893 to 2018). The publications are dedicated to various botanical directions - geobotanical, ecological and floristc studies, taxonomic and systematic study of fungi, algae, lichens, sporophytes, gymnosperms and flowering plants. Works on karyology, resource evaluation and plant life conservation are presented full enough. For the first time electronic publications, addresses which we know are included. The article deals with the short history and main directions of study of the plant life of Tyva.

Abstract >>
On April 19, 2018, in the Baikal Museum of the Irkutsk Scientifi c Centre SB RAS (Listvyanka, Irkutsk region, Russia) an inter-institutional scientific workshop was held. The workshop was dedicated to 125th anniversary of the outstanding botanist, Doctor of Sciences (Biology), Professor, Corresponding Member of the Ukrainian SSR Academy of Sciences Mikhail Grigorievich Popov (1893-1955). The workshop was attended by students, postgraduate students and researchers from four cities of Russia, as well as the closest relatives of M.G. Popov. Th e workshop presented six reports on important scientifi c issues identified by Mikhail Grigorievich, as well as two exhibitions and the presentation of a book devoted to the life, scientific and educational activities of M.G. Popov.
