Biennial. May. 



Root spindle-shaped, more or less tumid under the crown, and in 

 the variety /3 considerably large and fleshy, either white or yel- 

 lowish, more used in French cookery than with us. Stein erect, 

 branched, spreading, leafy, striated, 1^ or 2 feet high. Leaves 

 all smooth, most glaucous beneath ; radical ones lyrate, usually 

 disappearing before the plant blossoms ; those of the stem nu- 

 merous, the uppermost lanceolate and entire, lower ones gra- 

 dually broader, blunter, and more toothed, as they approach the 

 root, but all clasping, dilated and rounded at their insertion. 

 FL bright yellow, smaller than in the following species. Cul. 

 somewhat coloured ; the upper half spreading. Pods on slender 

 spreading stalks, at length often deflexed, round, with a beaded 

 appearance from the projection of the seeds ,- the beak angular, 

 barren. 



Cultivated in England chiefly for the sake of the abundant ex- 

 pressed oil of the seeds, the cake which remains serving for ma- 

 nure. 



2. B. Bapa. Common Turnip. 



Root stem-like, fleshy, orbicular, depressed. Radical leaves 



lyrate, rough ; those of the stem smooth ; the uppermost 



entire.
