Roots of 23 woody species are described anatomically. They are mostly from species uncommonly planted in the British Isles, and were unavailable at the time the Root Identification Manual of Trees and Shrubs (Cutler et al. 1987) was being written. They were collected from trees blown down in the stonn of October 1987, which uprooted over 15 million trees in the south and east of England. All but one (Tetracentron sinensis) are from the Royal Botanic Gardens, Kew, or Wakehurst Place.

Investigations of woody plants introduction, which have been conducted in Siberia and Mongolia, areanalyzed. It is noted that further investigations require complex study of trees and shrubs in the conditions of primaryintroduction. The aim is to introduce new trees and shrubs into the culture for various purpose artificial stands creation.The scientific tasks for development of woody plants introduction in Southern Siberia and Mongolia are outlined.

The genus Robinia is a small group of about 10 species of trees and shrubs indigenous only to NorthAmerica. Two species are endemic to Mexico, one being confined to south-western part of the country, while the rest are endemic to the south-eastern part of USA. Of the most important species and varieties of genus Robinia, Robinia x ambigua Poir.(Robinia viscosa x R. pseudo-acacia)-pink locust can be considered as the most significant one for bee-forage and decorative planting. In this paper a generative propagation method is presented for pink locust.

The Kalahari Gemsbok National Park exhibits some six major habitats. Away from the river beds the tree savanna is limited to the northern corner of the park, consisting of Acacia girajfae woodland and scattered dunes. The Nossob and Auobriverbeds and adjacent areas also harbour A. girqffae except in the south where A. haematoxylon becomes dominant, and where the Karoo flora increases. The dunes covered with trees and shrubs usually support Boscia albitrunca, A. mellifera and an occasional A. girqffae. Where the dunes are superficially without shrub vegetation, Stipagrostis amabilis is dominant, although low, shrub-like A. haematoxylon also occurs. The plains also contain low A. haematoxylon shrub and several dominant grasses. Pans are abundantand their vegetation is usually characterized by stands of Rhigozum trichotomum and Monechma incanum.

The South-East Coast of the Crimea has been developing as recreational region. Green planting is one of the factors that improve its recreational attraction. So it is important to study cultivated here arboreal trees and shrubs for perfection their assortment for landscape gardening. We analyzed taxonomy and biomorphological structure, botanicgeographical origin of dendroflora, the history of introduction, and the present state of cultivated arboreal plants. At present cultivated dendroflora totals 229 species belonging to 107 genus of 27 families. Magnoliophyta occupies 86,0 % of species diversity and the leading role among them belongs to Rosaceae (27,4 %), Oleaceae (6,6%), Leguminosae (5,6%). Pinophyta occupies 14,0 % of species diversity and the leading role belongs to Cupressaceae (50,0 %). Species of Mediterranean flora dominate (31,4 %). The most of them are well adapted to local climatic and soil conditions and provide “Mediterranean” appearance to cultural landscapes. More than a half (62,9 %) of the species diversity are deciduous trees (38,4 %) and shrubs (24,5 %). The proportion of evergreen plants is lower: coniferous trees – 13,5 %, and evergreen shrubs – 13,1 %. Selecting assortment of ornamental arboreal trees and shrubs should correspond to their ability to withstand summer drought and winter low temperatures.

The results of research of green areas in localities Malorechenskoye and Rybachye (South-Eastern Crimea) are presented. Large-scale landscaping of the studied territory was carried out in the 60-80-ies of the XX century. Modern structure of green spaces is typical for coastal settlements – basically, these are parks of recreational complexes, with high concentration of diversity of trees and shrubs species. A historical park (the oldest one) in the South-Eastern Crimea (late 50s – early 60s of the XIXth century) is also located in Malorechenskoye. The researches made taxonomic, botanical-geographical and biomorphological analysis of dendroflora. The frequency of occurrence of species, the condition of plants, as well as the degree of their drought and frost were assessed. The studied dendroflora includes 106 species belonging to 75 genera from 43 families. The species diversity of trees and shrubs in Rybachye is higher than in Malorechenskoye (89 and 67, respectively). At the same time, 13 species are widely distributed in both settlements, the most numerous of which is Cupressus sempervirens. It was revealed that species of the Mediterranean floristic region predominate (31.1 %), and representatives of native Crimean flora take a significant place (34.9 %). The leading position in the biomorphological structure of the dendroflora belongs to deciduous trees (25.5 %), followed by deciduous and evergreen deciduous shrubs (19.8 % each), and coniferous trees (17.0 %). The species diversity of deciduous shrubs and coniferous trees is significantly higher in Rybachye than in Malorechenskoye. Most plants are adapted to local climatic conditions: 57.5 % of species are not damaged by drought, the rest suffer from it in different degrees; 78.3% of species are frost-resistant, others are periodically damaged by low temperatures and need better protected from frost and cold winds planting sites. The absolute majority of species (95.3 %) are in good condition. Plants Aesculus hippocastanum, Buxus balearica, B. sempervirens, Euonimus japonica are more or less affected by pests and diseases. Special attention should be paid to the preserve the historical park in Malorechenskoye and to give it a protected status.
