Semiaquilegia adoxoides is a species of perennial flowering plant in the family Ranunculaceae. The species is native to Japan, Korea, and China, Now often considered the sole member of the genus Semiaquilegia, it bears similarities to members of the genus Aquilegia. S. adoxoides is native to China, Korea, and Japan and has an introduced population on Taiwan.
S. adoxoides can grow to about tall. The plant produces flowers that are usually white with purple tinging. Blooms occurs in March and April.

Taxonomy

The species was first described as a member of the genus Isopyrum by the Swiss botanist Augustin Pyramus de Candolle in 1818. In 1902, the Japanese botanist Tomitaro Makino segregated the genus Semiaquilegia and reclassified the species as Semiaquilegia adoxoides. In 1946, the American botanist Philip A. Munz rejected Makino's identification of Semiaquilegia as a distinct genus and reassigned the species to Isopyrum. Despite this, S. adoxoides remains accepted as the name for the species and is sometimes considered the sole example of the genus.

Distribution

Semiaquilegia adoxoides is considered native to central and southeastern China, Korea, and Japan. The species has an introduced population on Taiwan.

Cultivation

In 1946, Munz observed that S. adoxoides was occasionally sold by nurseymen for cultivation in the United States, though these plants were erroneously labeled as Aquilegia ecalcarata.
