ANNOTATION: This article presents a morphological analysis of Astragalus
sieversianus Pall., based on 25 herbarium specimens collected from the Fergana Valley
and preserved at the National Herbarium of Uzbekistan (TASH) between 1938 and
2018. Key traits including leaf morphology, floral structures, fruit shape, and seed
characteristics were examined. Results show a shift in distribution from lowlands to
foothill regions in recent decades, possibly due to anthropogenic impact and
environmental changes. Some morphological variability suggests the existence of local
ecotypes. The study highlights the importance of herbarium data in species monitoring
and indicates the need for further molecular research for conservation planning.
