Subspecies recurvata was first recorded from North America in 1880 on ballast in New Jersey (R. C. Rollins 1961, 1981, 1993; I. A. Al-Shehbaz 1985); it was first reported from North Carolina (as Brassica erucastrum) in 1958 from Yancey County and in 1968 from Jackson County (H. E. Ahles and A. E. Radford 1964; Al-Shehbaz).
