Sinapis arvensis. Fl. Dan. t. 678 ! 



In corn fields, a troublesome weed. 



Annual. June, July. 



Root tapering, slender. Herb rough with minute bristles. Stem 

 \\ or 2 feet high, glaucous, branched, leafy 3 its bristles pro- 

 minent and pungent. Leaves simply lyrate, bluntly toothed, 

 their terminal lobe rounded j upper ones oblong, or lanceolate, 

 acute, undivided, coarsely serrated. Fl. corymbose, numerous, 

 larger than in most of our common cruciform plants, either 

 straw-coloured, fading to white, or white from the beginning, 

 strongly veined with purple. Cal. a little spreading at the tips 

 only, generally bristly. Pods in long clusters, upright, knobbed 

 or apparently jointed, smooth, striated lengthwise when ripe, 

 terminating in the long, permanent, awl-shaped style, tipped 

 with the small stigma. The germen is divided into 2 cells, but 

 the partition is obliterated, and confounded in one spongy mass 

 as the pod ripens. Seeds large, globular, solitary in each joint. 



The plate in Ft. Dan. could here have been named from a most 

 slight inspection only j see Cardamine hirsuta. 



2. R. ?narih?Jius. Sea Radish. 



Pods jointed, deeply furrowed, of one cell. Radical leaves 

 interruptedly lyrate, serrated.
