G.L. Nesom. New localities have been identified for 10 sparsely distributed alien species: Abutilon theophrastii Medik., Celtis caucasica Willd., Consolida orientalis (J. Gay ex Gren. & Godr.) Schroedinger, Echinocystis lobata (Michx.) Torr. & A. Gray, Elodea canadensis Michx., Impatiens parviflora DС., Phytolacca americana L., Sisymbrium irio L., Solanum zelenetzkii Pojark., Symphoricarpos albus (L.) S.F. Blake.
