2. Sisymbrium loeselii L. (tall hedge mustard)

Pl. 328 h–j; Map 1392

Stems (20–)35–120(–175) cm long, usually sparsely to densely hairy, especially near the base, sometimes glabrous near the tip. Leaves 2–15 cm long, petiolate, lanceolate to lanceolate-triangular in outline, pinnately lobed or divided into 3–9 lobes, these entire to irregularly toothed or lobed, hairy or those of the uppermost leaves glabrous. Sepals 3–4 mm long. Petals 6–8 mm long. Style 0.5–0.7 mm long at fruiting. Fruits 2.0–3.5(–5.0) cm long, spreading or ascending at maturity, not appressed to the inflorescence axis, the stalk slender, noticeably narrower than the fruit. Seeds 40–60 per fruit, 0.7–1.0 mm long. 2n=14. May–October.

Introduced, widely scattered in mostly central Missouri (native of Europe, Asia; introduced widely in the U.S., Canada). Banks of streams and rivers; also levees, pastures, railroads, roadsides, and open, disturbed areas.

This species has become increasingly common during the past 35 years, but it remains restricted to mostly along railroads.
