Here we describe a new species of Corydalis sect. Corydalis (Fumariaceae), namely C. hirtipes B.U. Oh et J.G. Kim. This species, from the central part of Korea, is clearly distinguished from other species of sect. Corydalis by its simple, unicellular hairs that are densely distributed on the stems, peduncles, and petioles. It is also distinctive from its close relative C. albipetala in having ternate leaves, lobate or parted leaflets, dentate or cleft bracts, and broad, fusiform fruits.
