Abstract

A new species, Asarum koreanum (Aristolochiaceae), is described from Mount Gaseopsan, in Eumseong-gun, Chungcheongbuk-do, Korea. It is differentiated from the morphologically similar A. sieboldii, by the purple or light green leaves without white variegation, large flowers, and deep purple calyx lobes with dense multicellular glandular trichomes. In addition, this species only occurs in the Baekdudaegan mountain range of the central part of Korea (Chungcheongbuk-do), whereas A. sieboldii is extensively distributed throughout Korea, Japan, and China.
