Corydalis "Gruppe" Curviflorae Fedde, Repert. Spec. Nov. Regni Veg. 16: 197. 1919.

Herbs, perennial; stems and petioles of radical leaves attenuate to filiform underground base. Rhizome small, with fascicle of spindle-shaped to almost linear storage roots, apically with small pale bulblike bud; sometimes with thin stolons. Stems erect, slender, simple. Radical leaves small, ternate to biternate. Cauline leaves sessile, palmate. Fruiting pedicel erect. Corolla blue, yellow, or purple; upper petal with broad obtuse usually upturned spur; inner petals broad, with upper lateral wing conspicuous; dorsal crest broad, rounded, conspicuously overtopping petal apex. Stigma emarginate, with shortly stipitate apical papillae; geminate papillae usually only in basal corners. Capsule explosively dehiscent.
