Erysimum ochroleucum (Haller fil. ex Schleich.) DC. (Cruciferae), correct name for Erysimum humile Pers., nom. illeg., and the E. duriaei group classification

Abstract

Cheiranthus ochroleucus Haller fil. ex Schleich., basionym of the combination E. ochroleucum (Haller fil. ex Schleich.) DC., is a valid prioritary name over Erysimum humile Pers. It is not possible to differentiate morphologically E. ochroleucum from E. duriaei Boiss., s.l., and consequently the later and close related taxa are included in the former. The new combinations E.ochroleucum subsp. duriaei (Boiss.) G. López & Muñoz Garm., E. ochroleucum subsp. neumannii (Polatschek) G. López & Muñoz Garm. and E. ochroleucum subsp. gorbeanum (Polatschek) G. López & Muñoz Garm. are proposed.
