Erysimum thyrsoideum Boiss. View in CoL in Ann. Sci. Nat., Bot. ser. 2, 17: 79. March 1842 [nom. illeg.].

 Erysimum pycnophyllum J. Gay, Erysim. View in CoL Nov.: 3. January 1842.

Type: “Habitat in Armeniae monte Mouziourdag (Montbret! et Auch! in herb. mus. Par. et Webb.)”.

Lectotypus (designated here): TURKEY: “Armenia, Monzourdag ”, 1835, Aucher-Eloy 163 ( P [ P02272777 ]; isolecto-: FI [ 009694 ], G-BOIS [ G00154058 ], K [ K000075626 ]) .

Notes. – Boissier’s name is illegitimate because its holotype is a syntype of E. pycnophyllum .

The fragmentary G-BOIS duplicate was taken from the P specimen that was annotated by Boissier.

As indicated above, GAY (1842) cited two collections under his E. pycnophyllum . POLATSCHEK (2011) listed Aucher-Eloy 163 [P 02272777] as the holotype, thus failing to typify the name by overlooking Montbret’s syntype. Therefore, both E. pycnophyllum and illegitimate E. thyrsoideum are formally lectotypified here on the same sheet. An image of the Montbret syntype from Webb’s herbarium (#009694), which was annotated by J. Gay, was kindly sent by D. A. German.
