Alyssum suffrutescens Boiss., Fl. Orient. 1: 275. 1867 [nom. illeg.].

 Alyssum erosulum Gennari & Pestal. ex Clementi in Mem. Reale Accad. Sci. Torino ser. 2, 16: 248. 1855.

Note. – Alyssum suffrutescens is illegitimate because Boissier in Flora Orientalis listed the earlier published Alyssum erosulum Gennari & Pestal. ex Clementi as a synonym and indicated that it is a “nomen improprium”.
