The cultivation of this mustard is chiefly confined to the Sub- 

 Himalayan districts, where it is usually grown alone. In the Doab it is 

 cultivated generally as a subordinate crop in native vegetable gardens 

 mixed with carrotsjand other minor crops. There are two rather 

 distinct forms ; a tall later kind, 2-4 ft. high, is the var. dichotoma of F. 

 & G. Crops t. xl ; the other, a dwarf and earlier kind, is the var. 'i oria 

 of F. & G. Crops t. xla. The latter is largely grown on the Hima- 

 laya, and up to considerable elevations.
