This bright yellow-flowered Corydalis blossoms earlier than the Pink species, and is found along rocky woodland banks and in recent clearings from Quebec to Mackenzie, and south to Oregon, Arizona, Texas, Missouri, Wisconsin, and Pennsylvania. It is commonly low and spreading. The leaves are mostly short-stemmed, and are finely cut and divided, with the leaflets more wedge-shaped or broader than those of the latter species. The conspicuously spurred and nearly horizontal flowers are about half an inch long. They are golden yellow in colour, and the outer petals are ridged on the back. The seed pods are curved and spreading, and not erect and straight, like those of its pink sister. Corydalis is from an ancient Greek word, Korydalos, a lark, and alludes to the spur of the flower as resembling that of the lark. It is found from March to May.
