Alyssum macrostylum Boiss. & A. Huet in Boiss., Fl. Orient. 1: 279. 1867 [nom. illeg.].

 Alyssum xanthocarpum Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 154. 1842.

Type: “Hab. in incultis Armeniae ad Erzeroum (Auch. exs. 4098 A!, Huet!), ad Baibout (Bourg. sub. A. montano), in monte Akdagh Syriae bor. (Auch. exs. 263!), in montibus Ciliciae Kurdicae (Ky exs. 130!) [Aucher Eloy] N. 263 Akdag; [Aucher Eloy] 4098 A. Erzeroum”.

Lectotypus: see Alyssum xanthocarpum Boiss. entry above.

Note. – Under Alyssum macrostylum, Boissier in Flora Orientalis cited both syntypes (Aucher-Eloy 263 from Akdag and Aucher-Eloy 4098A from Erzeroum) of the earlier published A. xanthocarpum and erroneously placed the latter in the synonymy of the former (see above).
