In its wild state this is an erect, sim- 

 ple, or scarcely branched annual, 1 to 

 2 feet high. Lower leaves green and 

 slighly glaucous, more or less pinnately 

 divided, with a large terminal lobe, and 

 rough with stiff hairs, which are some- 

 times very copious, and rarely entirely 

 wanting ; upper leaves narrow-oblong 

 or lanceolate, clasping the stem with 

 rounded projecting auricles. Flowers 

 and pods much like those of the Cabbage, 

 but the petals are usually of a brighter 

 yellow. 



On borders of fields, and waste places, 

 throughout Europe and Russian Asia. 

 A frequent weed of cultivation in Britain. 

 Fl. spring and summer. The cultivated 

 varieties include the Turnip (B. Napus), 

 the Bapeseed or Colza (B. Bapa), and 

 probably also the Swedish Turnip.
