Species of the genus Allium (Amaryllidaceae) in the territory of the National Park "Khvalinsky" (Saratov region)

For the period from 1927 to 2024, 90 sheets from the territory of the Khvalynsky National Park, Saratov Region, belonging to 10 species of the genus Allium were collected in the herbarium funds of the Saratov State University (SARAT) and the herbarium of the Khvalynsky National Park. The revision of the herbarium collections contributed to the classification of the species diversity of the onions of the Khvalynsky National Park (references to A. decipiens refer to A. tulipifolium ). However, despite the wide time range of collections on the territory of the park, the presence of the species A. flavum subsp. tauricum and A. sphaerocephalon indicated in the literary sources has not been confirmed.
