3. Corydalis flavula (Raf.) DC. (pale corydalis, yellow fumewort, yellow harlequin)

Pl. 418 g, h; Map 1863

Plants green or sometimes dull gray and more or less glaucous. Stems 5–30 cm long, mostly loosely ascending from a spreading base. Basal and lower stem leaves with the petiole 4–8 cm long, the upper leaves usually sessile. Leaf blades 1–4 cm long, with 5 or 7 pinnae, these deeply several-lobed, the ultimate segments linear to narrowly oblong or less commonly broadly elliptic. Inflorescences mostly not extending past the foliage, those with open flowers (3–)6–12-flowered racemes, those with cleistogamous flowers 1–5-flowered clusters. Flower stalks (except sometimes in cleistogamous flowers) (6–)9–22 mm long, ascending at flowering, often pendant at fruiting. Corollas pale yellow or less commonly brighter yellow, the upper outer petal 7–9 mm long, the spur (except in cleistogamous flowers) 1.5–2.0 mm long, incurved, the concave apical portion usually with an irregular, wavy or toothed crest. Fruits 14–25 mm long, relatively straight, glabrous, not appearing mealy. Seeds 1.9–2.1 mm long, the surface finely pebbled, the sharply angled rim with a minute marginal ridge. 2n=16. March–May.

Scattered, mostly south of the Missouri River (eastern [mostly northeastern] U.S. west to Nebraska and Oklahoma; Canada). Bottomland forests, mesic upland forests in ravines, bases of bluffs, banks of streams and rivers; also shaded roadsides.

This is the most abundant species of Corydalis in the state. It is a relatively inconspicuous wildflower. Some or all of the flowers on a plant often are cleistogamous.
