 lower ones deeply pinnatifid ; the superior ones linear, and 

 almost entire. Silirpies smooth, pendulous, three-celled, long- 

 taper beaked ; seeds white. 



From Nepal, where the plant is cultivated, Dr. Buchanan 

 sent seeds to the Botanic garden at Calcutta in 1802, where 

 the plants thrive luxuriantly, and blossom and ripen their 

 seeds durino- the cold season. 



Stem annual, erect, smooth, Mith smooth, erect branches; 

 whole height about three or four i'eet. Leaves, all stem-clasp-

 and somewhat glaucous. Racemes terminal, and axillary. 

 Flowers large, erect, yellow. Siliques long-pedicelled ; im- 

 mediately after the decay of the flowers, the pedicels become 

 perfectly recurved, and the siliques pendidous; they are all 

 smooth, three-celled, and on that account much larger and 

 broader than those of many other species. Beak long, half 

 the length of the pods, taper. Seeds numerous, large, round, 

 smooth, white.

 thrive well during the cold season. They blossom in March, 

 and ripen their seed in April. 



Root annual, large, white and tapering, subfuciform with nu- 

 merous spreading lateral fibres. Stem erect and smooth, with
