Alyssopsis deflexa Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 58. 1842 [nom. illeg.].

 Nasturtium sagittatum (Aiton) W.T. Aiton, Hort. Kew. ed. 2, 4: 111. 1812.

= Alyssopsis mollis (Jacq.) O.E. Schulz in Engl., Pflanzenr. 86: 186. 1924.

Notes. – Alyssopsis deflexa is illegitimate because BOISSIER (1842a) listed the earlier published Nasturtium sagittatum (Aiton) W.T. Aiton as a synonym.

Boissier then reduced in Flora Orientalis A. deflexa to synonymy of A. sagittata (Aiton) Boiss., but his combination is illegitimate also because he listed Sisymbrium molle Jacq. (1787) as a synonym, a name that predates S. sagittatum Aiton (1789) .
