Herbs, perennial, with small short vertical rhizome with apical leaf rosette. Stems ascending to erect or procumbent at base, leafy, usually branched, arising from below leaf rosette; lower bract leaflike, upper much smaller. Flowers pale yellow, purple, blue or white. Capsule pendent from straight pedicel, explosively dehiscent.
Seven species: Bhutan, China, India (Assam), Myanmar; seven species (five endemic) in China.
The sectional epithet is derived from the initial letters of the specific epithets of the seven included species.
Corydalis kiukiangensis (species no. 176) might be better placed here than in C. sect. Asterostigma.
