Boiss., Fl. Orient. 1: 199. 1867 .  Cheiranthus crassicaulis Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 45. 1842 . Type: “[Aucher-Eloy] Ispahan absque numero ”. Holotypus : IRAN : “ Ispahan ”, s.d., Aucher-Eloy s .n. ( P [ P02272710] ; iso-: G-BOIS [ G00332133 ], P [ P02272709 ]) . Notes. – Both duplicates at P have the catalogue (not collection) number 1442 . The single material that Boissier examined for the species description was P 02272710 , which he annotated and from which he took a fragment consisting of an upper cauline leaf and three flowering tips. He did not annotate P 02272709 and, most certainly did not examine it. JAFRI (1973: 234) arbitrarily indicated that the type is at G , though he did not examine nor annotate it. By contrast, POLATSCHEK (2010: 251) designated P 02272709 as the lectotype , and one of us (IAS) erroneously annotated it in 2016 as such. However, that sheet is less complete and does not show the inflated and thickened stem as does P 02272710 . In our opinion, no lectotypification is necessary, and P 02272710 ought to be considered as the holotype (see BOISSIER, 1841a ).
