Eruca vesicaria is a species of Eruca native to the western Mediterranean region, in Morocco, Algeria, Spain and Portugal. It is closely related to Eruca sativa, which is included in E. vesicaria by some botanists either as a subspecies E. vesicaria subsp. sativa or not distinguished at all. E. vesicaria can be distinguished from E. sativa by its persistent sepals. Both plants are referred to by the same common names as E. sativa.
