System

This species was in 1753 under the name Brassica vesicaria by Carl Linnaeus in Species Plantarum, Volume 2, page 668, published first. She was commissioned in 1802 by Antonio José Cavanilles in Descripción de las Plantas, page 426 in the genus Eruca. The genus name Eruca 1754, first published by Philip Miller in The Gardeners Dictionary ..., 4th Edition, Volume 1. A synonym for Eruca is Velleruca Pomel. The botanical genus name Eruca is derived from the Latin word uro for burning and refers to the burning taste of the seeds.

The genus Eruca Mill belongs to the tribe Brassicaceae in the family Brassicaceae. Many erucic species have been published, but is only a species name valid.

There are in the genus Eruca just the way Eruca vesicaria (L.) Cav. with two subspecies:

  • Eruca vesicaria (L.) Cav. subsp. vesicaria
  • Garden Senfrauke ( Eruca sativa subsp vesicaria (Mill.) Thellung. ): She is a also known as rocket, widespread crop.
