The general habit is characterized by a predominantly erect structure, offering some flexibility to the stems, which gives the plant an airy and dynamic appearance. Varieties such as Corydalis flexuosa can have an upright habit with slightly flexible and drooping branches, spreading for about 20 to 40 cm.\u003c\/p\u003e\n\n \u003cp\u003eTheir underground system consists of a \u003cstrong\u003esolid bulb or tuber\u003c\/strong\u003e , as is the case for Corydalis solida, which is distinguished from tunicate bulbs. This tuber, rounded to ovoid in shape, compact and solid, generally measures between 1 and 3 cm in diameter when mature. Its outer skin is beige to pale brown in color, and its inner flesh is white to cream. This tuber, without a husk or tunic, is particularly sensitive to drying out, requiring rapid planting after receipt to ensure its recovery.

They are generally bipinnate to quadripinnate, composed of numerous leaflets or segments which are themselves divided.
