Flower/Fruit: Fl. Per.: March-May.
Type: Type: Described from Asia.
Distribution: Distribution: Probably wild in C. Asia (Asiatic origin) ; cultivated extensively and introduced in most parts of the world. Often found as an escape from cultivation.
Comment/Acknowledgements: Some authors recognize three varieties, glabrous, sparsely hispid, and hispid (Blatter in J. Bombay Nat. Hist. Soc., 34 (3) : 299, 1930) which are of doubtful taxonomic value, as it is impossible to draw a definite line between these indumen¬tum characters and their constancy. Much honey is collected by insects from its flowers and seeds are oil producing (both fatty oil and volatile “mustard” oil.
