Anatomical Review of Certain Carnations of North Caucasus

The article provides an anatomical review of 32 species of the genus Dianthus L. representatives шт Caucasus, i.e. information about the anatomy of their stem. Most of the studied species have a narrow ecology and are confined to different altitudinal zones. The experience of the introduction of these species in the botanical garden of the Chechen State Pedagogical University of Grozny in the conditions of the steppe climate indicates wide ecological amplitude and potential adaptive capabilities of the species. The main limiting factor in the distribution of these species in natural conditions is probably their low competitiveness. Anatomical signs, apparently, do not have any taxonomic significance. The similarity of the anatomical structure of the stems of the Caucasus carnations is evident even in species that are well differentiated morphologically. Anatomical differences between them are mainly quantitative. The smallest taxonomic values for the anatomical features of carnations are the radial dimensions of the epidermal cells, the mechanical (sclerenchymal) ring, conducting system. The most significant for these purposes are the morphological features: the size of the calyx and capsule, the shape and degree of dissection of the lobule plate, the shape and size of the chaffs

Orchidaceae Juss. in Flora of Chechnya and Their Protection

For the first time, perennial materials on the Orchidacaeae Juss. family of Chechnya are summarizedб consisting of 15 families and 29 species. The largest genus in the family – Orchis L. is represented by 8 species. The article presents information that all members of the family are protected plants listed in the Red Book of Chechnya, Ingushetia, Dagestan, and the Stavropol Territory. Some species are not included in the list of plants to be protected, including those species that have underground tuberoids and can serve as a source of salep (for instance, Platanthera bifolia, P. chlorantha, Herminium monorchis, Traunsteinera sphaerica, Dactylorhisa incarnata, D. salina, D. urvilleana). In this connection, data on the resources of family members and the potential possibilities of their use as a medicinal raw material are of interest. We have carried out resource studies of the most common species of Orchis tridentata Scop, within the North Caucasus. The obtained data allow us to expand our understanding of the species role of Orchidaceae Juss family.

Floristic Research of the Biological Reserve “Bragunsky”

Flora of the biological reserve “Bragunsky” of republican significance, located on the territory of three districts of the Chechen Republic (area of 17,000 hectares, forest land – 10.2 thousand hectares) is studied. Its boundaries are indicated. Preliminary studies in the summer-autumn flora of the reserve have revealed 237 species from 175 genera and 53 families, among which more than 15 endemics are of different statuses, 25 relict species are of different geological eras. Dominant by the number of family species are indicated (Asteraceae, Lamiaceae, Rosaceae, Poaceae, Fabaceae, Caryophyllaceae, Apiaceae, Brassicaceae, Cyperaceae, Scrophyliaceae, Orchidaceae), Geographic elements are considered. The general-holarctic and boreal nature of the flora is noted with a significant participation of ancient Mediterranean and binding elements. The prevalence of hemicryptophytes in the reserve flora has been noted – 115 (49.78 %) species, 48 therophytes (20.25 %) and 40 phanerophytes (10 %) and a slight presence of cryptophytes – 4.21 %. The economically and scientifically valuable, as well as rare, red book and protected species are listed
