Geranium purpureum Vill.: A new casual alien plant in Korea
Naturalization centers are hotspots where accidently introduced seeds first germinate and grow. Railways play important roles as corridors for movement, having positive effects on species dispersal and persistence, though they can also be invasion routes for undesirable plants. Geranium purpureum Vill., a new alien species in Korea, was found at the Bumil Railway Station, Busan, Gyeongsangnam-do, Korea. Most native Geranium species in Korea belong to the subgenus Geranium and section Geranium, but G. purpureum belongs to the subgenus Robertium and section Ruberta, with the “carpel-projection” method of seed dispersal. In other countries, G. purpureum is often compared with G. robertianum L., which is an ornamental plant in Korea. We assume that G. purpureum is a casual alien plant and that it is not likely to spread to other provinces, as it scarcely survives when the mean temperature in January is below 4°C. Moreover, it has not been found further north than Busan. We provide a key of allied taxa, information about the habitat, a description of the morphological characters, illustrations, and photographs.
