초록

We performed taxonomic reviews and habitat circumstances survey for 41 un-introduced environmentallyharmful plants (as designated by the Ministry of Environment, Korea in 2016). For this purpose, we investigated plantspecimens from several herbaria and performed a field survey in the southeastern region of the United States. Base on theresult, we presented the most comprehensive results of weed risk evaluation and taxonomic description up to now as well asclassification keys for 11 species to apply the regulation management of putative invasive alien species – Centaureamaculosa Lam., Centaurea diffusa Lam., Mikania micrantha Kunth. (Asteraceae), Cenchrus echinatus L., Neyraudiareynaudiana (Kunth) Keng ex Hitchcock, Brachiaria mutica (Forsskål) Stapf, Vulpia bromoides (L.) Gray, Loliumpersicum Boissier & Hohennacker, Setaria palmifolia (J. Konig) Stapf (Poaceae), Prosopis glandulosa Torr. (Fabaceae),Fallopia baldschuanica (Regel) Hobub. (Polygonaceae).
