Abstract

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.

紫色天竺葵:韩国一种新的外来植物
归化中心是偶然引入的种子首先发芽和生长的热点。铁路作为迁徙的走廊发挥着重要作用,对物种的扩散和持久性产生了积极影响,尽管它们也可能是不良植物的入侵路线。紫天竺葵。,在韩国庆尚南道釜山Bumil火车站发现了一种新的外来物种。韩国本土的大多数天竺葵属物种都属于天竺葵亚属和天竺葵科,但紫色天竺葵属Robertium亚属和Ruberta亚属,采用种子传播的“心皮投影”方法。在其他国家,人们经常将紫丁香与韩国的观赏植物robertianum L.进行比较。我们假设紫丁香是一种偶然的外来植物,它不太可能传播到其他省份,因为当1月份的平均温度低于4°C时,它几乎无法存活。此外,在釜山以北的地方还没有发现过它。我们提供了相关分类群的关键、栖息地的信息、形态特征的描述、插图和照片。
