New and rare adventitious species of vascular plants in the Sverdlovsk Region

The article provides an information about the finds of six adventitious plant species in the Sverdlovsk Region, two of them are new to the flora of the region (Hesperis pycnotricha Borbás et Degen., Nepeta sibirica L.). Four species (Lotus corniculatus L., Silene dichotoma Ehrh., Urtica cannabina L., Vicia amoena Fisch.) were previously known from 1–2 localities in the Sverdlovsk Region and are rare adventitious species not only in the region, but also in adjacent territories. The presented information about new localities of adventitious species will become the basis for monitoring their distribution in the studied region in particular, and in the Urals as a whole.
