only R. rugosum has persisted with naturalized populations. Rapistrum perenne (Linnaeus) Allioni was first collected in 1922 from southeastern Saskatchewan but has not been seen or collected from there since 1932. It can be distinguished by being a perennial with a conical style shorter than the strongly 8-ribbed terminal segment, whereas R. rugosum is an annual with a slender, filiform style longer than the slightly ribbed terminal segment.</p> |tables= |references= }}<!-- --><!-- -->{{#Taxon: name=Rapistrum |author=Suzanne I.
