Erucastrum arabicum Fisch. & C.A. Mey., Index Sem. Hort. Petrop. 5: 35. 1839.

 Brassica schimperi Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 86. 1842 [nom. illeg.].

Note. – Brassica schimperi is illegitimate because BOISSIER (1842a) listed the earlier published Erucastrum arabicum as a synonym. Later Boissier in Flora Orientalis reversed the assignment and placed the former species in the synonymy of the latter.
