Notes: FNA7: "Of the three subspecies of Sinapis alba recognized in European and North African floras, only subsp. alba is naturalized in the New World. This taxon is an important crop plant, and is occasionally reported as a weedy escape from cultivation. Its seeds are used for the manufacture of condiment mustard (see also 17. Brassica), pickling spice, and production of oils for soap and mayonnaise, lubrication, and cooking (I. A. Al-Shehbaz 1985)."
