NEWS - Researchers from Chungbuk National University in Cheongju and the National Institute of Biological Resources in Incheon report Impatiens jangjeonense (Balsaminaceae) as a new species from the mountainous region of Gangwon-do Province in South Korea. The new species inhabits mountainous habitats at elevations of 400–1200 meters and is often found in shaded valleys near streams. I. jangjeonense coexists with I. hambaeksanensis on Mount Hambaeksan, Gangwon-do. However, populations of both species are completely isolated from each other, making gene flow between the two species unlikely. The genus Impatiens exhibits great variation in morphology. Flower color and morphology vary greatly, along with diverse capsule and seed shapes. In particular, a variety of organ colors, shapes, and sizes are observed within the same species or the same population. Partly because of this variability, the taxonomy of Impatiens has proven challenging. I. jangjeonense is morphologically similar to
