It was defined that on its territory there are 5,355 examples of trees and shrubs out of 95 taxa from 79 genera and 41 families. Tree species dominate, there are 61 species of them, and there are 34 species of shrubs. 523 examples of 4 tree species from the Crimean Red Book grow there. 131 tree examples are valuable and secular ones.

The estimation results of the nature-conservation value of the south-eastern Crimea erosional and denuded landscapes have been presented. The synopsis of the biotopes, which require specific conservation measures, has been given. It includes 41 units, 29 of which have the international conservation status in accordance with Resolution No. 4 of Bern Convention. Forty biotopes are the habitats of the rare plant species listed in the Red Lists of different levels. The information about the distribution of the endangered biotopes and their occurrence on the specially protected natural areas has been provided. The great phytosozological significance of the natural landscapes of the region has been confirmed.

The data on the yield and component composition of essential oil Santolina chamaecyparissus L. and Santolina rosmarinifolia L. from the collection of the Nikitsky Botanical Garden (the Southern Coast of the Crimea) are given. The yield of the essential oil in the aerial mass of Santolina chamaecyparissus is 0.35% of the Wet weight, S. rosmarinifolia - 0.2%, in the inflorescences S. chamaecyparissus - traces (0.08%), in the inflorescences S. rosmarinifolia - 0.91% . The main components of Santolina chamaecyparissus essential oil are α + β-santolinenone (41.6%), terpeniol-4-ol (6.67%), borneol (4.78%), α-terpineol (4.39%), α -fellandren (3.98%), S. rosmarinifolia -α + β-santolinenone (21.34%), terpineol-4-ol (11.19%), α-fellandrene (7.57%), linalol (4.14%), borneol (3.3%), limonene (3.01%).

The article presents the research results of the genesis of the elements of the male generative sphere Asphodeline lutea (L.) Rchb. The types of formation of the microsporangium wall and the male gametophyte of asphodelinous fierce (centripetal type, successive type of microsporogenesis, 2-cell of pollen grains) are shown. The morphophysiological features of the male gametophyte, indicating their high potential for pollination and fertilization under natural habitat conditions, have been established.

The results of the study of anther and male gametophyte formation are presented. The wall microsporangium is developed centrifugally and it was shown while analyzing permanent preparations of buds. In the formed state of the wall anther is composed of epidermis, endothecium, a middle layer and 2 - 3 layers of cells of tapetum of a secrеtory type. Sporogenous tissue is formed with a single layer of cells. The wall of a maturе anther is represented with two layers of cells: epidermis and irregular double layer endothecium. Microsporogenesis runs on a simultaneous type. Mature pollen grains of J. officinale are three-cells. In the middle samples of pollen morphologically normal pollen grains dominate, their amount is around 80%.

Present in literature soils’ classifications according to the measure of their skeletal peculiarities and bedding of rocks' depth are reviewed. A betterment necessity of a universal scientific classification and of an applicative one working out is shown.

A detailed soil survey of plots under the grove of Lebanon cedars ( Cedrus livani A. Rich) was carried out. The relationship between the edaphic factors and the state of trees was studied. The soil suitability of plots has been determined and the recommendations of their improvement for essential oils and medicinal plants were given.

The intrinsic-thoughtful characteristics of estimation procedure for the results of an intellectual activity obtained in a scientific institution has been given in the article.
