2. Corydalis crystallina (Torr. & A. Gray) Engelm. ex A. Gray (mealy corydalis)

Pl. 418 d, e; Map 1862

Plants green or more commonly gray and glaucous. Stems 10–40 cm long, loosely to strongly ascending, sometimes from a spreading base. Basal and lower stem leaves with the petiole 3–6 cm long, the upper leaves sessile or very short-petiolate. Leaf blades 1.5–8.0 cm long, with mostly 7 or 9 pinnae, these again 1 or 2 times deeply several-lobed, the ultimate segments linear to narrowly oblong or lanceolate. Inflorescences mostly extending past the foliage, all with open flowers, (4–)8–20-flowered racemes. Flower stalks 1–2 mm long, ascending at flowering and fruiting. Corollas bright yellow, the upper outer petal 15–22 mm long, the spur 6–8 mm long, straight or nearly so, the concave apical portion with an irregularly wavy or toothed crest. Fruits 10–20 mm long, straight or slightly curved, moderately to densely pubescent with short, white, bladderlike, inflated hairs, appearing mealy. Seeds 2.0–2.3 mm long, the surface finely pebbled (best observed with magnification), the bluntly to sharply angled rim lacking a marginal ridge. 2n=16. April–June.

Scattered in western Missouri, mostly south of the Missouri River, east locally to Clark County and the city of St. Louis. (Missouri and Kansas south to Oklahoma, Texas, and Arkansas). Glades, upland prairies; also railroads, roadsides, and open disturbed areas.

This distinctive species is most often found growing on acidic substrates.
