Erysimum gladiiferum Boiss. & Hausskn. in Boiss., Fl. Orient. Suppl.: 40. 1888. Type: “Hab. in graminosis calcareis montis Pir Omar Gudrun Kurdistaniae Persicae 3–6000' (Haussk.!)”. Holotypus: IRAQ: “In gramin. calc. Pir Omar Gudrun”, 3000'– 6000' [910 – 1820 m], VI.1867, Haussknecht 71 (G-BOIS [G00154039]; iso-: B [B100068654], BM [BM000522227], BP, JE [JE00002774, JE00002775, JE00002776], K [K000075621], P [P5354979, P05354980], W [W0026710]). Note. – The G-BOIS holotype is a collection folder of five sheets, of which two have the exact collection data, another two lack the printed label, and the fifth has the same printed label with Mesopotamia handwritten on it and with Polatschek annotation in 2005. Erysimum boryanum Boiss. & Spruner in Boiss., Diagn. Pl. Orient. 1: 71. 1843. Type: “Hab. in rupestribus montanis, Pentelicus, Parnes in Atticâ, montes Arcadiae (Boiss. Sprunner), in Messeniâ (Bory)”. Lectotypus (designated by POLATSCHEK & SNOGERUP, 2002: 133): GREECE: “Sommet et flancs du Pentélique”, IV.s.a., Spruner s.n. (G-BOIS [G00332150]; isolecto-: LD [LD1064662]). Syntypus: GREECE: “Pentelicus”, V.1842, Boissier s.n. (G [G00446064, G00446065, G000446066], KW [KW000127964], W [W0077277]). Notes. – POLATSCHEK & SNOGERUP (2002) indicated an isolectotype at W, but that specimen was collected by Boissier not Spruner. All three syntypes at G belong to the Reuter-Barbey herbarium, and despite search in several major herbaria, Bory’s collection from Messenia was not found. Erysimum boryanum var. atticum (Boiss.) Boiss., Fl. Orient. 1: 205. 1867.  Erysimum atticum Boiss., Diagn. Pl. Orient. ser. 2, 1: 25. 1854. Type: “Hab. in faucibus Hymetti meridionalis et in monte Corydalo Atticae (Heldr. et Sartori)”. Holotypus: GREECE: “in faucibus Hymetti meridionalis”, VI.1844, Satori & Heldreich 1838 (G-BOIS [G00332149]). Notes. – No duplicates of this type collection are found in the major herbaria consulted, and the G-BOIS sheet ought to be recognized as the holotype. Therefore, the designation of that sheet by POLATSCHEK & SNOGERUP (2002: 132) as a lectotype was unnecessary.
