Biennials; short-lived; sexual; caudex not evident. Stems usually 1 per plant, arising from center of rosette near ground surface, 2–7.5 dm, sparsely pubescent proximally, trichomes simple, to 0.5 mm, or glabrous throughout. Basal leaves: blade oblanceolate, 5–18 mm wide, margins lyrate-pinnatifid, often ciliate-mucronate on lobes, trichomes minute, surfaces glabrous or sparsely pubescent, trichomes simple, 0.1–0.5 mm. Cauline leaves: 10–45, often concealing stem proximally; blade auricles 1–5 mm, surfaces glabrous. Racemes 18–47-flowered, sometimes branched. Fruiting pedicels suberect to divaricate-ascending, straight or slightly curved, 5–13 mm, glabrous. Flowers ascending at anthesis; sepals glabrous; petals white, 5–10 × 1–1.5 mm, glabrous; pollen ellipsoid. Fruits ascending to divaricate-ascending, not appressed to rachis, not secund, curved, edges parallel, 6–11 cm × 1.5–2 mm; valves glabrous; ovules 60–86 per ovary; style 0.1–1 mm. Seeds uniseriate, 1.2–2 × 1–1.2 mm; wing continuous, 0.1–0.4 mm wide.
Phenology: Flowering Mar–Jun.
Habitat: Rocky bluffs, wooded slopes, valley bottoms
Elevation: 50-300 m
Distribution
Ark., Conn., Ga., Ill., Ky., Mass., Mich., Minn., Mo., N.Y., N.C., Okla., S.C., Wis.
Discussion
Boechera missouriensis occasionally has been treated as a variety of B. laevigata. With its significantly longer petals (5–10 versus 3–5 mm) and distinctive, lyrate-pinnatifid basal leaves that persist well beyond anthesis, it warrants recognition as a species.
