Erysimum filifolium Boiss. & Hausskn. in Boiss., Fl. Orient. Suppl.: 41. 1888 [nom. illeg.] [non F. Muell.].

 Erysimum boissieri Polatschek in Phyton (Horn) 34: 200. 1994.

Type: “Hab. in rupestribus calcareis montis Avroman Kurdistaniae Persicae 5–6000' (Haussk.!)”.

Holotypus: IRAN-IRAQ: “In rup. calc. m. Avroman”, 5000'–6000' [1520 –1830 m], VII.1867, Haussknecht 72 (G-BOIS [G 00154037]; iso-: B [B 100068744], JE [JE 00002737], K [K 000075623], W [W 0026674]).

Notes. – The G-BOIS holotype is a collection folder of three sheets, of which one has the full collection data listed above on a printed label with “Montes Avroman et Schahu” indicated, another has only Mesopotamia written on the same printed label and was annotated by Polatschek in 2005 as isotype, and the third is unlabeled.

POLATSCHEK (1994) renamed Boissier’s illegitimate name as E. boissieri, but he later (POLATSCHEK, 2011) erroneously indicated the JE00002737 as the lectotype.
