African turnip weed - eastern (Sisymbrium thellungii)



African turnip is a weedy brassicaceous species. Brassicaceous weeds belong to the Brassicaceae (mustard/turnip) family (formerly called Cruciferae) which comprises about 338 genera and 3709 species. In Australia, there are about 215 brassicaceous species belonging to 57 genera. Over half of these species are native and several of the introduced species are the source of important vegetable crops and oils. However, most of the exotic species have become weeds and many of these are significant problems in Australia’s cropping zone.


African turnip weed has limited distribution within northern NSW yet has the potential for further spread to areas with heavy soils.
