A new species, Corydalis bonghwaensis M. Kim & H. Jo, is described here. It is found on a mountain slope in Bongwha-gun, Gyeongsangbuk-do, Korea. Corydalis bonghwaensis shares several characteristics (white flowers, glabrous pedicels, white tubers, and the polygonal stigma) with related species C. namdoensis B. U. Oh & J. G. Kim and C. albipetala B. U. Oh. However, this new species has flowers which change from pale-yellow to white, a mucronated inner-petal apex, linear leaflets, and fusiform capsules with two-rowed seeds. In contrast, C. namdoensis has retuse inner-petal apex, various leaflets, and fusiform capsules with 2-rowed seeds. C. albipetala has retuse inner-petal apex, elliptical leaflets, and linear capsule with 1-rowed seeds. Also C. humilis B. U. Oh & Y. S. Kim has pale-blue purple flowers, elliptical leaflets, inflorescence with 1-5 flowers, and hemispherical lower-outer petal.

A new species of Corydalis sect. Corydalis (Fumariaceae), Corydalis cornupetala Y.H. Kim et J.H. Jeong is described from Gyeongsan-si, Gyeongsangbuk-do in Korea. This new species is distinguished from the other species of the sect. Corydalis by some flower characters such as, purplish white petal with two dark stripes and horn-shaped apex of outer petal. The linear leaflets of C. cornupetala are similar to the lineariloba type of C. remota Fisch. ex Max. or C. namdoensis B.U. Oh et J.G. Kim, but much longer and narrower. The linear or lanceolate bract of C. cornupetala is also distinctive from the elliptical shape of C. remota and C. namdoensis.
