Chrysosplenium aureobracteatum Y. I. Kim & Y. D. Kim (Saxifragaceae) is described as a new species from Gangwon Province in central Korea. The new taxonomic entity, which was uncovered previously by molecular systematic study, resembles C. sphaerospermum Maxim. but is readily distinguishable by its golden bracteal leaves and by the long internodal distances of the distal leaf pairs on sterile branches such that leaf pairs are not clustered. Further, the two species exhibit clear differences in their seed coat morphology, which is considered an important diagnostic character in the genus.
