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.

The species of Corydalis cornupetala Y.H.Kim et J.H.Jeong Which is belong to the Corydaliaceae is only distributed at the Gyaejeong Forest in Gyeongsan. As one of the spring ephemeral plants, this species has limited growing period. The present study is on site characteristics and vegetation structure in the wild habitats of Corydalis cornupetala Y.H.Kim et J.H.Jeong and offers basic information on habitat conservation including recovery plan. The soil texture is silty loam and soil acidity is ranged as pH 5.4~5.9. The electric conductivity was 0.22-0.50 ds/m and soil organic content is ranged as 7.61~15.78 %. Fifty nine vascular plants were identified from 5 quadrats. According to the two way cluster analysis applied by the PC-ORD, the community was classified as Acer ginnala, Vicia amoena and Stellaria aquatica. The habitat of Corydalis cornupetala Y.H.Kim et J.H.Jeong was determined by the dissimilarity indices rather than the species number of appearance. Species diversity was 1.26, and dominance and evenness were found to be 0.08 and 0.92, respectively.
