“…Ряд представителей семейства (Asteraceae, Fabaceae, Tamaricaceae и др. ), являясь доминантами и эдификаторами многих пустынных сообществ, играют важную роль в сложении растительного покрова (Курочкина, Оспанова, 1973;Курочкина, 1978;Курочкина и др., 1984;Осмонали, 2021;Osmonali et al, 2022).…”

The purpose of the research was to identify the features of the floristic composition of rammunities with representatives of the genus Salsola L. (North-Western (Aksai), Southem, South-Eastem regions of Kazakhstan). Traditional methods of field geobotanical researches were used in the process of studying. As a result of expedition works, 24 studied plant communities (with predominance and participation of various Salsola) were described. Communities differed from each other by species composition, which is caused by a variety of combination of habitat factors. The analysis of the floristic composition of the described rommunities resulted in the identification of two groups: 1) rommunities dominated by species of the genus Salsola; 2) rommunities in which the presence of species of the genus Salsola was insignificant. During the research, it was revealed that annual species S. nitraria Pall. and S. tragus L. are well adapted to the habitat conditions of desert and semi-desert regions and it was roncluded that they can be used for reclamation of disturbed lands.

The article discusses the results of comparative analysis of morphological, anatomical and molecular-genetic structure of species Arthrophytum longibracteatum, Arthrophytum balchaschense, Haloxylon aphyllum). Morphological-anatomical and molecular-genetic methods were used during the study. Transverse sections were viewed using a Levenhuk Zoom&Joy microscope (China), images of transverse sections were taken with a Levenhuk D740T 5.1 camera, using the LevenhukLite programme. To clarify the correctness of species identification, the collected specimens were compared with the Type specimen of Arthrophytum balchaschense stored at the Institute of Botany and Phytointroduction (AA). Other herbarium specimens of this species stored in the AA Herbarium (Almaty, Kazakhstan) and herbarium collections: MW (Moscow, Russia), LE (St. Petersburg, Russia), TASH (Tashkent, Uzbekistan) were also reviewed. With the help of QGIS programme, a map of the location points of the studied specimens was made. The conducted studies allowed to form a proof base of clear belonging of Arthrophytum balchaschense to the genus Haloxylon. This circumstance became the reason for the necessity of nomenclatural changes consisting in assignment of Arthrophytum balchaschense to the genus Haloxylon under the name Haloxylon balchaschense (Iljin) Osmonali, Veselova & Kudab. This species has a central-eastern-North Turanian distribution, being endemic to the flora of Kazakhstan.

We compiled a checklist of endemic vascular plants occurring in Kazakhstan, employing an exhaustive examination of literature sources, herbarium collections, databases and field observations. Our study reveals that 451 taxa can be considered endemic to Kazakhstan, constituting 7.97% of the total vascular plant diversity in the country. These endemic taxa, originating from 139 genera and 34 families, predominantly thrive in the southern regions of Kazakhstan, specifically in the mountain ridges of the Kazakh part of the Tian Shan, including Karatau (123 taxa), Dzungarian Alatau (80 taxa) and Trans-Ili and Kungey Alatau (50 taxa). Notably, 107 endemic species are granted legal protection. Detailed information regarding life form, life cycle, conservation status and geographical distribution across floristic regions was meticulously compiled for each endemic taxon. Of the six groups of life forms, herbs include the highest part of endemic taxa (367 taxa), followed by dwarf semishrubs (25 taxa), shrubs (23 taxa), subshrubs (20 taxa), undershrubs (13 taxa) and trees (3 taxa). The observed life cycles are perennials (408 taxa), annuals (33 taxa) and biennials (10 taxa). This paper serves as a fundamental groundwork for prospective investigations aimed at assessing population sizes and hotspots of plant endemism throughout Kazakhstan, crucial for determining conservation status of endemic plants.
