Erysimum crassicaule (Boiss.) Boiss., Fl. View in CoL View at ENA Orient. 1: 199. 1867.

 Cheiranthus crassicaulis Boiss. View in CoL 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).
