Lepidium erinaceum Boiss., Diagn. Pl. Orient. 6: 17. 1846.

 Aethionema erinaceum (Boiss.) Khosravi & Mumm. in Nordic J. Bot. 26: 29. 2008.

Type: “Hab. in alpe Kuh-Daëna Persiae australis Kotschy No. 701”.

Holotypus: IRAN: “In alpe Kuh-Daëna”, 20.VII.1842, Kotschy 701 (G-BOIS [G00154026]; iso-: B [B100241671], BM [BM001172147], CAS [CAS00123206], E [E00077261], FI [FI 005689], K [K000642707], KW [KW000127997], LE, MO [MO1926529], P [P05330964, P05330965, P05330966], PR [PR 375027], PRC [PRC455628], W [W18890020395], WAG [WAG0004278], WU [WU0059756, WU0101802], Z [Z00078596]) .

Notes. – The isotypes have printed label with same information as in the holotype but with phrase “Habitu siliculisque lineari-oblongis distinct species”.

THELLUNG (1906a) placed Lepidium erinaceum in a monospecific Acanthocardamum Thell., where it remained accepted by all subsequent works, including HEDGE (1968), APPEL & AL-SHEHBAZ (2003), and AL-SHEHBAZ et al. (2006). However, KHOSRAVI et al. (2008a) have established beyond a doubt that the species is perfectly nested within Aethionema . Their listing of the holotype in G-BOIS is correct because Boissier based the species description on that specimen alone.
