Annotation: This article describes an analysis of the genus Astragalus L., which was stored in the herbarium fund of the Department of Biology of Kokand State University (KD). Analysis revealed that 57 herbarium specimens from 11 species of the genus Astragalus were stored. Keyword: Astragalus ferganensis, herbarium, flora, Middle Asia, Ferghana valley. Introduction.In recent years, targeted research has been conducted on certain families, genera, and species stored in various large herbarium collections worldwide, and inventories of herbarium collections have been conducted. Because of the inventories of certain families, genera, and species stored in the herbarium funds of the National Herbarium of Uzbekistan (TASH), the largest herbarium fund in Middle Asia, and Samarkand State University (SAMDU), research is being conducted on specimens stored in these herbarium funds, and the results have been published [3,4]. In 2024, the smallest herbarium fund in Uzbekistan was established at the Department of Biology (KD) of the Kokand State Pedagogical Institute, which contributed to the study of Uzbekistan and global biodiversity [8]. From 2024 to the present, analysis of the Fabaceae, Lamiaceae, and Boraginaceae families has been conducted in the KD herbarium fund. In particular, the herbarium fund contained 35 herbarium specimens belonging to 8 genera of the Lamiaceae family, 87 belonging to 13 genera of the Fabaceae family, and 116 belonging to 8 genera of the Boraginaceae family [6,7,8].

Herbariums stored in the KD fund are used in floristic research of specific regions and in the study of rare and endemic plant species [7].

The works ‘Conspectus Florae Asiae Mediae’ (1981), ‘Flora of Uzbekistan’ (1961), and the taxon name databases POWO (2025) and IPNI (2025) were used to identify herbarium specimens [1,5,9,10]. Results and discussion.Establishing a herbarium fund for the Department of Biology (KD) of Kokand State University is an important step in the study of the flora of Uzbekistan. The newly established herbarium fund is considered important for the formation of the flora composition of the Ferghana Valley for the study of rare and endemic plant species. Herbarium specimens belonging to the genus Astragalus L. were stored in the herbarium fund (KD) of the Department of Biology of Kokand State University. As a result, 57 herbarium specimens belonging to 10 species of the genus Astragalus were stored (Table).

Fedtsch. ex Korol. and A. rubellus Gontsch. It is a rare endemic species in the Ferghana Valley (Fig.1-2). Conclusion. As a result of the analysis of herbarium specimens stored in the KD herbarium fund, it is necessary to enrich the herbarium specimens of rarely collected and uncollected species of the genus Astragalus. This is important for university students studying biodiversity and mastering botany science. Figure 1. Astragalus ophiocarpus Benth. ex Boiss. (KD)
