Semiaquilegia adoxoides (DC.) Makino, a native species of the Ranunculaceae distributed in mainland China, western Japan, and South Korea, has recently been found in central Taiwan, adding a new record for this genus and species to the flora of this island. Semiaquilegia can be easily distinguished from other genera of the Ranunculaceae by its actinomorphic flowers, distinct petals, and free carpels. This paper provides descriptions of the genus and species, line drawing, and color photos.
