The inventory of the genus Anabasis L. collection in the herbaria of Kazakhstan and neighboring countries, particularly the specimens of the endemic and relict species Anabasis cretacea Pall., comprised this study. Systematizing and analyzing the herbarium collection focused on species diversity, their morphological characteristics, and ecological implications. The endemic species received special attention, highlighting the need for their conservation and preservation. The studied herbaria included the Institute of Botany and Phytointroduction and Al-Farabi Kazakh National University in Almaty, the Astana Botanical Garden and National Center of Biotechnology in Astana, and the Utemisov West Kazakhstan University in Uralsk. The collection made in Kazakhstan’s own herbaria took place during field research in June-August 2025. Likewise, a visit to the personal herbaria of Prof. S.A. Aipeisova was fruitful. Similarly, virtual tours of herbaria took place in the study. These were Lomonosov Moscow State University; the N.V. Tsitsin State Library of the Russian Academy of Sciences; the V.L. Botanic Institute, Komarova RAS, St. Petersburg; and the Digital Herbarium of the Central Siberian Botanical Garden SB RAS, Novosibirsk. Thus, studying the various herbaria resulted in the 13 different species of the genus Anabasis L. found in Kazakhstan, five of which were in the Aktobe Region. Moreover, the location of the species Anabasis cretacea Pall succeeded in its identification in the study area at the Aktobe Region, Kazakhstan.

Analysis of the genus Anabasis L. collection revealed the species diversity, distribution ranges, and ecological preferences, including relict and endemic types with the highest tolerance to salinity and drought. The results were of scientific and conservation values, providing insights into soil and environmental conditions, aridization processes, and speciation. The identification of the genus Anabasis L. species was successful in the study area at the Aktobe Region, Kazakhstan.
