A new species of Eranthis (Ranunculaceae), E. pungdoensis B.U. Oh is described from Pung-do, Ansan-si, Gyeonggi-do in Korea. The new species is distinct from E. byunsanensis, its closely relative species, in having broad funnelform petals, 2.5-3.7 mm long, 2.4-3.5 mm wide and restricted distributional area.

This study was carried out to find specific characters of the seed morphology and anatomy of Korean Eranthis in Ranunculaceae. As a result, E. byunsanensis differs with E. stellata on the basis of presence of unicellular hairs on the seed surface. E. stellata has no unicellular hairs on its seed surface. On the other hand, E. byunsanensis bears such unicellular hairs derived from epidermal cells of the seed surface. Besides other morphological characters used when it was published as a new species, the presence of unicellular hairs on the seed surface strongly supports it as an endemic species of Korea. In addition, to compare the seed morphology of E. pinnatifida and E. pungdoensis, for which mature seeds were not available at this time, an additional study should be conducted in near future.
