''Eruca'' is a genus of flowering plants in the family Brassicaceae, native to the Mediterranean region. The number of species is disputed, with some authorities only accepting a single species, while others accept up to five species. The following species are accepted by the Med-Checklist:〔Med-Checklist: (''Eruca'' )〕〔Med-Checklist: (''Eruca vesicaria'' aggregate )〕 *''Eruca loncholoma'' (Pomel) O.E.Schulz *''Eruca pinnatifida'' (Desf.) Pomel (syn. ''E. sativa'' subsp. ''pinnatifida'' (Desf.) Batt.; ''E. vesicaria'' subsp. ''pinnatifida'' (Desf.) Emberger & Maire) *''Eruca sativa'' Mill. (syn. ''E. vesicaria'' subsp. ''sativa'' (Mill.) Thell.) *''Eruca setulosa'' Boiss. & Reuter *''Eruca vesicaria'' (L.) Cav. When treated as a monospecific genus, all are included within ''E. vesicaria''.〔Flora of China: (''Eruca'' )〕〔Flora Europaea: (''Eruca'' )〕 They are annual plants growing to 20–100 cm tall. The leaves are deeply pinnately lobed with four to ten small lateral lobes and a large terminal lobe. The flowers are 2–4 cm diameter, arranged in a corymb, with the typical Brassicaceae flower structure; the petals are creamy white with purple veins, and the stamens yellow. The fruit is a siliqua (pod) 12–25 mm long with an apical beak, and containing several seeds.〔Blamey, M. & Grey-Wilson, C. (1989). ''Flora of Britain and Northern Europe''.
