The range of most species of the genus Cotoneaster Medik. located in the mountainous regions of Asia.According to the latest report by Janette Fryer and Bertil Hylmo, the genus Cotoneaster is represented by 2 subgenuses,11 sections and 37 series. Cotoneasters of Siberian flora: C. commixtus, C. laxiflorus, C. lucidus, C. megalocarpus, C. multiflorus, C. popovii, C. tjulinae, C. uniflorus, C. yakuticus, located in 2 subgenuses, 4 sections, 4 series. Collection of speciesof the genus Cotoneaster in the Botanical Garden acad. A.V. Fomin was created according the method of genus complexesby F. N. Rusanov, starting from 1972. The source material was attracted both by the extraction of seeds from the catalogsof foreign and Russian botanical gardens, and by the collection of seeds and living material in places of natural growth.Two expeditions were carried out to the regions of Siberia. The first one – Yakutsk in 1982 (10.08 – 29.08) along the route Kiev – Novosibirsk – Irkutsk – Tomsk – Krasnoyarsk – Aldan – Irkutsk – Kiev. The second – Central Siberian in 1983(24.07 – 17.08) along the route: Kiev – Irkutsk – Davsha – Nizhne –Angarsk – Severo –Baikalsk – Ulan –Ude – Kyakhta –Irkutsk – Chita – Moscow – Kiev. Morphological descriptions of annual shoots leaves, flowers, fruits, seeds of three typesof Cotoneasters: C. laxiflorus, C. lucidus, C. neo-popovii, micrographs of endocarp of bones, columns are given. The material is illustrated with photographs of plants introduced in the north-west of Ukraine (Kiev).

The main task of the expeditions was the search for the following species of natural Siberian flora and theintroduction of live plants and seeds to the Botanical Garden named after acad. A. V. Fomin: Cotoneaster mongolicus.C. neo-popvii, C. tjulinae, which are currently presented in our collection. In addition, long-term phenological observations in the conditions of the north-west of Ukraine allowed to isolate new species from the imported material: C. kyachticus.C. logginovii. They are described in the materials of the XIV and XVII conferences “Problems of botany of Southern Siberiaand Mongolia”. A trip to the lake Zun-Torei was dedicated to the search for C. mongolicus. As it turned out later, under theC. mongolicus mother’s plant, we dug up a plant different from the mother’s plant, to which we gave the name C. logginovii.This article provides materials to identify the parents pair in the formation of this hybrid pitchfork. For this purpose,materials of herbarium collections from the vicinity of the lake were used Zun-Torei experienced local botanists, as wellas personal fees. Comparison of the samples allowed to establish their identity with C. mongolicus, as well as to certify it asone of the parents of C. logginovii. Morphological descriptions of annual shoots leaves, flowers, fruits, seeds of three typesof Cotoneasters: C. megalocarpus, C. mongolicus, C. yakuticus; micrographs of endocarp of bones of the previous speciesand C. logginovii, C. melanocarpus, C. uniflorus are given. The herbarium samples of C. mongolicus collected in the areaof the lake Zun-Torey were analyzed. The material is illustrated with photographs of plants introduced in the north-westof Ukraine (Kiev). The introduction of plants by the method of genus complexes by F. N. Rusanov allowed to create theCotoneaster collection, which includes 200 taxa of the genus. In the Botanical Garden named after acad. A .V. Fomin fromthe flora of Siberia preserved 11 species of Cotoneaster: C. commixtus, C. kyachticus. C laxiflorus. C. logginovii, C. lucidus,C. neo-popovii, C. megalocarpus, C. mongolicus, C. tjulinae, C. uniflorus, C. yakuticus.

Introduction Experiment

Some results of cultivation of Siberian flora species in culture at the introduction nursery of useful plantsof the Peter the Great Botanical Garden of the BIN RAS, in St. Petersburg have been summed up. All species are classifiedaccording to biological resistance. The analysis of the introduction resistance of plants in Siberia showed that 83.3 % ofthe species adapted well to the new conditions of existence. According to the duration of the introduction experiment,all plants were divided into 5 groups. 37 % falls on the group of species, the life expectancy of which is more than 60years. 45 species of rare and endangered flora of Southern Siberia, grown in culture, have been identified, most of themcan be attributed to resistant (46.7 %) and highly resistant species (31.1 %). The maximum age of these plants in theexperiment reaches 68–84 years. The data obtained can be used to preserve and enrich regional flora and prepare materialfor repatriation work.

AbstractA summary of the techniques used and results obtained from three oversnow traverses in Marie Byrd Land and the Ellsworth Highland between January 1957 and January 1959 is presented. Seismic reflection shooting at 30 nautical mile (55.5 km.) intervals was combined with gravity, magnetic and altimetric measurements to determine the glacial and subglacial topography. It was found that a vast portion of West Antarctica has an ice–rock interface well below sea-level. A major connecting channel with a maximum depth of more than 2,500 m. below sea-level exists between the Ross and Bellingshausen–Amundsen Seas, whereas there is no major topographic connection between the Ross and Weddell Seas. This channel divides West Antarctica into two provinces with granite and rocks of sedimentary origin to the east and south, and a volcanic region to the north-west. Present ice flow is outward from two high areas, centred over mountainous regions on either side of the channel. It is concluded that the present ice sheet has grown from the convergence of the two smaller ice sheets which formed in the mountainous areas and joined across the intervening open water.

The region of Turkey whose Classical sites and monuments are discussed in this article lies wholly within the Western Taurus mountains, and consists of the eastern section of “the West Taurus Lake District”—as modern geographers now call it. The foothills of Taurus which extend around the south-western edge of the Konya Plain define both its northern and eastern limits; its western are established by the massive ranges which separate Lake Beyşehir from Lake Eğridir. Between these two mountainous regions, which join the main heights of Taurus further south, lies the rift valley occupied by Lake Beyşehir and the now partly-drained Lake Suğla.Here is to be found the borderland of Pisidia and Lycaonia, as indicated by Strabo. To the north-west and north lies Phrygia Paroreius; to the south, the borderland of Pamphylia and Cilicia Tracheia; and to the south-east, Isauria.

And Function

The Department of Botany on the Potchefstroom Campus (formerly Potchefstroom University for Christian Higher Education) of the North-West University (NWU) had its centenary in 2020. In this paper we celebrate this milestone by giving an overview of the history of the Department at this  campus, including its recent establishment and expansion on the NWU Mahikeng Campus (formerly the University of North-West). A brief overview is presented of the advances in teaching and research over the years, and the development and relevance of the important plant collections in the botanical garden, two herbaria and the national diatom collection. The main emphasis of this contribution is, however, a reflection on the advancement and significance of research conducted by various disciplines on plant and algae function, diversity and ecological restoration over the years. The different disciplines in Botany at NWU, from the oldest to the more recent, are Plant Taxonomy, Plant Ecophysiology, Terrestrial Plant Ecology, Aquatic Sciences, Urban and Settlement Ecology, Geoecology, and Proteomics. Different aspects contributing to changes occurring in the environment, such as pollution, land degradation, urbanisation, overexploitation of resources and the subsequent effect of these on plant diversity and function are especially addressed in our current research. The results of our research inter alia led to solutions for problems occurring in the landscape and contribute to the well-being of the people using the land and water by restoring important ecosystem services.
