In fields, waste ground, and on banks by road sides. 



Annual. June, July. 



A taller plant, with round smooth branches, more spreading than 

 either of the foregoing. Lower leaves large, lyrate, rough, va- 

 riously lobed and toothed ; upper ones stalked, smooth, narrow, 

 entire, spreading or dependent. Fl. smaller than in the two 

 former. Cal. yellowish, widely spreading, but not quite liori- 

 zontal. Pet. obovate. Pods small, obtusely quadrangular, 

 nearly even, and smooth, tipped with the permanent, quadran- 

 gular, somewhat elongated, style, and capitate stigma; but want- 

 ing the proper, often seed-bearing, beak of this genus, though 

 the style finally becomes tumid at the base. Seeds several, 

 brown, sufficiently known for their domestic use, and stimulating- 

 medical properties. 



All the figures of the old authors, J. Bauhin's excepted, are copies 

 of Matthiolus, and are all defective, as wanting the narrow, en- 

 tire, more or less pendulous^ upper leaves, so characteristic of 

 the present species. 



4. S. tenidfolia. Narrow-leaved Wall Mustard. 



Pods erect, on s])reading stalks, linear, compressed, slightly 

 beaked. Seeds two-ranked. Leaves once or twice pin- 

 natifid; the uppermost undivided. Stem smooth.
