The materials presented in the article supplement the information of “Flora of the middle zone of the European part of Russia” (Maevskiy, 2014) for the floras of Voronezh and Lipetsk Regions. The materials were collected in the period 2007–2020 on the protected areas of Usmansky Bor: in the Voronezhsky State Reserve, its protected zone and in the Federal Preserve “Voronezhsky”. The flora of the Lipetsk Region is supplemented by 9 species: Alchemilla argutiserrata, Aronia mitschurinii, Carex remota, C. tomentosa, Centaurea majorovii, Cotoneaster lucidus, Hieracium sylvularum, Scirpoides holoschoenus, Symphoricarpos albus. The data on 11 new taxa are given for the Voronezh Region flora: Cotoneaster lucidus, Crataegus ucrainica, Hieracium sylvularum, Nymphaea × marliacea, Phytolacca acinosa, Philadelphus latifolius, P. serotina, Spiraea chamaedryfolia, Thuja occidentalis, Veronica polita, Wolffia globosa. The article reports on new finds of Carex bohemica and Prunus cerasifera, species that were previously noted in the region, but not included in “Flora ...” (Maevskiy, 2014). Among the 20 marked species, 11 taxa are alien ornamental plants and fruit trees and shrubs noted outside of cultivation areas. Leaving the places of cultivation by alien plants and naturalization in natural communities is a modern problem of protected areas in the European part of Russia.
