Records of new alien species of vascular plants in the Yamalo-Nenets autonomous region (Russia).

Abstract

In the course of floristic researches in Priuralsky district of Yamalo-Nenets Autonomous Region (YANAR) we have made new findings complementing the species composition of vascular flora in the territory of the Region. Below we present the data on 10 new species of alien vascular plants for the YANAR flora collected by us in 2016 year - Carduus crispus L., Leucanthemum ircutianum Turcz. ex DC., Picris hieracioides L., Euphorbia virgata Waldst. et Kit., Lupinus polyphyllus Lindl., Trifolium arvense L., T. montanum L., Phacelia tanacetifolia Benth., Plantago uliginosa F. W. Schmidt and Sorbaria sorbifolia (L.) A. Br. To clarify the status of the alien species, the following criteria were used: a large separation of the findings from the main area, the mention of its introduction to the neighboring region, as well as the presence only in disturbed habitats. Only the status of Plantago uliginosa remains unclear, as it was collected on the banks of Ob' river and may be wild in YANAR, unlike P. major s. str.
