Recent field and herbarium studies have yielded three vascular plant taxa of the family Poaceae that have been documented in Korea. All of the three species, collected from Jeolla-do and adjacent areas, were introduced and naturalized. Three species are identified as Vulpia bromoides (L.) Gray, Agrostis capillaris L. and Eragrostis pectinacea (Michx.) Nees. We provide the descriptions and descriptive photos of these species. Keys to the newly recorded species and related taxa are also provided.

Vulpia octoflora (Walter) Rydb., a newly identified invasive alien species, was found in Gangcheon-ri, Yeoju-si, Gyeonggi-do, South Korea. It is native to North America and has been reported to be an invasive alien plant in Japan, Australia, and Ukraine. Vulpia octoflora is a weed that grows mainly in dry sandy or rocky soil and is frequently found along the roadside in open areas or in artificially disturbed sites. This species is similar to the recently confirmed alert alien species, V. bromoides (L.) Gray, but is readily distinguishable due to more florets per spikelet and a short awn of the lemma. A detailed species description, the geographical distribution, illustrations, photographs, and an identification key for all species of Vulpia that occur in Korea are provided.

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