Semiaquilegia quelpaertensis (Ranunculaceae), a new species from the Republic of Korea

Abstract

Semiaquilegia quelpaertensis sp. nov., a new species belonging to the family Ranunculaceae, from Hallasan National Park in Jeju-do, Republic of Korea, is described and illustrated. The new species is similar to Semiaquilegia adoxoides (DC.) Makino, but can be readily distinguished by a thick underground stem, shallowly lobed leaflets, larger flowers, (4–)6 staminodes and conspicuously rugose tuberculate seed surface.
